Agv presentation
A convergent boundary occurs when two tectonic plates move toward each other, with one plate subducting under the other. This can create a subduction zone and result in volcanic activity and earthquakes along the boundary. When one plate subducts downward into the mantle, it melts from the heat and pressure, causing volcanoes to form on the other plate above.
How tides work
Tides are caused by the gravitational pull of the moon and sun on Earth's oceans, with the moon having the strongest influence due to its closer proximity. Other factors like strong winds, underwater seismic events, and explosions can also influence tidal patterns and heights to a lesser extent. The regular waxing and waning of the tides is due to Earth's revolution around the sun and the moon's revolution around Earth.
Earthquake Basics
Seismology is the study of earthquakes, which occur when stress causes rocks under the Earth's crust to elastically deform until they break, rebounding and snapping back into their original shape. This elastic rebound releases energy in the form of seismic waves, causing the shaking that defines an earthquake. Faults form from tectonic stresses and are breaks in the Earth's crust. The focus is the point within the earth where an earthquake originates, while the epicenter is the point on the surface directly above the focus.
Our changing earth
Earth is the third planet from the Sun and the only object in the Universe known to harbor life. According to radiometric dating and other sources of evidence, Earth formed over 4 billion years ago.[24][25][26] Earth's gravity interacts with other objects in space, especially the Sun and the Moon, Earth's only natural satellite. Earth revolves around the Sun in 365.26 days, a period known as an Earth year. During this time, Earth rotates about its axis about 366.26 times.[n 5]
Earth's axis of rotation is tilted, producing seasonal variations on the planet's surface.[27] The gravitational interaction between the Earth and Moon causes ocean tides, stabilizes the Earth's orientation on its axis, and gradually slows its rotation.[28] Earth is the densest planet in the Solar System and the largest of the four terrestrial planets.
Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earth's surface is covered with water, mostly by oceans.[29] The remaining 29% is land consisting of continents and islands that together have many lakes, rivers and other sources of water that contribute to the hydrosphere. The majority of Earth's polar regions are covered in ice, including the Antarctic ice sheet and the sea ice of the Arctic ice pack. Earth's interior remains active with a solid iron inner core, a liquid outer core that generates the Earth's magnetic field, and a convecting mantle that drives plate tectonics.
Within the first billion years of Earth's history, life appeared in the oceans and began to affect the Earth's atmosphere and surface, leading to the proliferation of aerobic and anaerobic organisms. Some geological evidence indicates that life may have arisen as much as 4.1 billion years ago. Since then, the combination of Earth's distance from the Sun, physical properties, and geological history have allowed life to evolve and thrive.[30][31] In the history of the Earth, biodiversity has gone through long periods of expansion, occasionally punctuated by mass extinction events. Over 99% of all species[32] that ever lived on Earth are extinct.[33][34] Estimates of the number of species on Earth today vary widely;[35][36][37] most species have not been described.[38] Over 7.4 billion humans live on Earth and depend on its biosphere and natural resources for their survival. Humans have developed diverse societies and cultures; politically, the world has about 200 sovereign states.

The document discusses plate tectonics and how it relates to volcanoes and earthquakes. It explains that volcanoes occur when plates move apart and spew hot lava, while earthquakes happen when plates rub together in opposite directions. Plate tectonics was proposed in the 1960s and suggests that Earth's outer layer is made of plates that float on the asthenosphere, causing volcanic eruptions and earthquakes that can damage homes and infrastructure.
Science 4.3.5
This document discusses how various natural forces shape the Earth's surface through erosion and deposition over long periods of time. It provides examples of how wind erodes rock formations into unique shapes over hundreds of thousands of years. Waves similarly erode cliffs by carrying away tiny pieces. The Grand Canyon was formed by different erosion processes over millions of years. Glaciers can also reshape landscapes by pushing material as they advance and withdraw, leaving gouges that become features like the Great Lakes. The Appalachian Mountains have eroded from their original height due to weathering over extremely long timescales.

Plate tectonics
Mantle convection is the driving force behind plate tectonics. Heat rises within the Earth's mantle, causing the lithosphere plates to move over long periods of time. Mantle plumes are abnormally hot regions within the mantle that can partially melt and cause volcanism when they reach the Earth's surface. Hot spots form as oceanic plates move over mantle plumes, creating volcanic island chains. Plate tectonics results in geological structures like folds and faults at plate boundaries and causes the formation of mountain ranges, rift valleys at spreading centers, and deep ocean trenches.

Chapter 12 Volcanoes
Volcanoes form at boundaries where tectonic plates meet, such as at divergent boundaries like the Mid-Atlantic Ridge or at convergent boundaries. The type of eruption depends on the composition of the magma and amount of gases; basaltic magma produces quiet eruptions while magma rich in silica or water causes explosive eruptions. The resulting volcano shape is also influenced by the eruption - shield volcanoes form from fluid basalt lava, cinder cones from tephra ejected in explosions, and composite volcanoes feature layers from both eruption types.
Our Changing Earth (Grade 7)
1. The document discusses the two main types of forces that cause changes on Earth's surface: endogenic (endogenous) forces and exogenic (exogenous) forces.
2. Endogenic forces occur beneath the surface and cause natural disasters like earthquakes, volcanoes, and changes in landforms. They result from plate tectonic activity.
3. Exogenic forces occur above the surface and include the erosional and depositional forces of air, water, ice, and wind. They shape landforms at the Earth's surface like sea caves, sand dunes, and deltas.
Our changing earth
This document provides information about different types of earth movements and landforms. It discusses endogenic and exogenic forces that cause volcanoes and earthquakes from within and outside the earth. Volcanoes form from magma rising through cracks and releasing pressure at plate boundaries. Earthquakes result from vibrations caused by plate movement, with an epicenter and focus point. Weathering and erosion shape the landscape over time, forming features like waterfalls, meanders, and oxbow lakes in rivers and sea caves, arches, and stacks along coastal regions. Wind can also shape the earth, producing mushroom rocks in deserts and sand dunes that accumulate when winds slow.
Earthquakes
Earthquakes occur along fault lines as a result of tectonic plate movement and built up stress being released. They can cause significant damage depending on their magnitude, proximity to populated areas, and local soil and construction practices. Major earthquake zones exist along plate boundaries where tectonic plates converge, diverge, or move past each other. The largest, most destructive quakes occur in subduction zones. To minimize earthquake risk, communities can educate citizens, construct earthquake-resistant buildings, and implement emergency planning and insurance.
Erosional forces
Erosion is the wearing away and movement of surface materials by forces like water, wind, or glaciers. There are several types of erosion including plucking by glaciers, which picks up debris, and abrasion, where wind acts like a sandblaster wearing down rocks. Wind erosion can scatter dust over large areas through deflation and form sand dunes or dust storms in dry, unvegetated regions. Glaciers are powerful erosion agents that can carve U-shaped valleys and leave behind deposits like moraines, eskers, and till when they melt. Erosion shapes the Earth's surface over time.
Liquefaction
An earthquake is caused by the sudden displacement of rock in the Earth's crust due to crustal strain, volcanoes, landslides, or collapsing caverns. Earthquakes can cause ground shaking, landslides, fires, soil liquefaction, tsunamis, floods, and damage human infrastructure. Soil liquefaction occurs when saturated granular soils like silty sands or sandy gravels lose strength during an earthquake or sudden stress change and behave like liquid, which can damage buildings and cause them to sink or tilt.
The rockcycle
The rock cycle describes how rocks are continuously transformed between three main types - igneous, sedimentary, and metamorphic rocks - through geological processes such as erosion, deposition, burial, melting, and crystallization. Igneous rock is weathered into sediment and deposited to form sedimentary rock, which is then buried and altered by heat and pressure into metamorphic rock. Metamorphic rock can be melted into magma and erupt as new igneous rock, restarting the cycle.
Makeup of the earth, lesson 1
The document discusses the different types of landforms found on Earth's surface, which make up 1/4 of the planet not covered by water. It describes mountains, plains, and plateaus as the main landforms. It then focuses on how volcanoes and earthquakes continually change and shape the surface by creating new land features, destroying existing ones, and causing the ground to shake, respectively. Volcanoes form from magma breaking through the crust, while earthquakes are caused by movements along faults in the Earth's tectonic plates.
Weathering and erosion
The document discusses how the Earth's surface is constantly changing through various weathering and erosion processes. It describes three main types of weathering - physical weathering caused by water, wind, and ice, which breaks down rock and sediment. Erosion is then defined as the movement and transport of this weathered material by water, wind, ice, or gravity. Specific examples of erosion by each of these forces are given, such as glacial erosion, water erosion, and landslides caused by gravity. The document concludes by discussing related geologic processes like deposition, which forms new landforms over time like deltas, canyons, meanders, and floodplains through the deposition of eroded sediments.
2.3 - Internal Forces
The document summarizes plate tectonics and its relationship to various geological phenomena. There are three main types of plate boundaries - divergent where plates move apart, convergent where they collide in subduction or collision zones, and transform where they slide past each other. Plate movement is responsible for volcanoes, earthquakes, and mountain building. Earthquakes occur when stress builds up at faults until the plates suddenly slip, releasing energy. Tsunamis are large sea waves generated by earthquakes or landslides that flood coastal areas.

Slides on our changing earth
The lithospheric plates slowly move due to movement of magma inside the Earth, causing changes on the surface. During an earthquake, safe spots are under sturdy furniture away from fireplaces, windows and falling objects. People should spread awareness about earthquake preparedness among friends and family. A 1999 earthquake in Bhuj, India measured 6.9 on the Richter scale.

Chapter 2 section 3
Internal Forces Shaping the Earth discusses plate tectonics and how the movement of tectonic plates causes earthquakes and volcanic activity. Tectonic plates move in four main ways - spreading, subduction, collision, and shearing - which reshapes the Earth's surface over time. Earthquakes occur when plates suddenly slip or grind past each other at fault lines. Most earthquakes and volcanoes are located at boundaries where tectonic plates meet, such as the Ring of Fire around the Pacific Ocean.
Our earth
The document discusses various geological features formed by different earth processes. It describes lithospheric plates, which are composed of continental and oceanic plates, and how earthquakes and volcanoes commonly occur at their boundaries. It then explains different landforms created by internal forces like volcanoes and earthquakes, and external forces like weathering, erosion, wind and water flow including glaciers, sand dunes, waterfalls and deltas.
Kane's Presentation
Earthquakes occur when tectonic plates shift beneath the Earth's surface, causing the ground to shake and sometimes displace. Large offshore earthquakes can displace the seabed enough to create tsunamis. Earthquakes may also trigger landslides or volcanic eruptions in rare cases. Volcanic eruptions happen when gas and magma build up underground, releasing lava, rocks, and ash during more explosive eruptions. Eruptions with less gas and thicker magma tend to be less dramatic and result in lava flows from the vent.

Earthquake power point
The document discusses earthquakes and their causes and effects. It notes that earthquakes can kill people and damage buildings when they occur. The movement of tectonic plates beneath the earth's surface can cause earthquakes when the plates shift or collide. A specific earthquake that occurred in Beijing in June 2011 is described, where over 1,000 structures were destroyed, at least 25 people were killed, and 250 were injured. Rescue workers helped survivors and orphaned children were taken in by other families.

This document summarizes the key forces that shape the Earth's surface - lithospheric plates, endogenic forces from inside the Earth, and exogenic forces from outside. It provides examples of specific landforms created by these forces, including earthquakes, volcanoes, rivers, sea waves, glaciers, and wind. Rivers form landforms like waterfalls, meanders, ox-bow lakes, deltas, and floodplains. Sea waves create sea caves, arches, stacks, and sea cliffs. Glaciers form lakes and moraines, while wind shapes mushroom rocks, sand dunes, and loess deposits.
Why does it seems that the sun move
The document discusses the motion of the Earth and how it causes day and night as well as apparent motion of the sun. It explains that the Earth rotates on its axis every 24 hours, which causes one side of the Earth to face the sun while the other side faces away, creating day and night. It also discusses how the Earth revolves around the sun over the course of 365 days.

All living things go through life cycles that involve different stages of development. The butterfly's life cycle has four main stages: egg, caterpillar, pupa, and adult butterfly. As a caterpillar, it eats leaves and grows quickly before forming a pupa and undergoing transformation inside until emerging as a young butterfly and finally a mature adult butterfly that can lay new eggs.
How can a simple machine reduce force
Simple machines make work easier by changing the amount or direction of force needed. There are six basic types of simple machines: the lever, pulley, wheel and axle, inclined plane, screw, and wedge. Compound machines combine two or more simple machines; examples include scissors, bicycles, and wheelbarrows.

How does soil affect living things
The document discusses the formation and composition of soil. It explains that soil is formed over long periods of time through the weathering and breakdown of rocks and the decomposition of dead plants and animals. The soil is made up of weathered rocks, humus from decomposed materials, and minerals. It has distinct layers with varying properties including the topsoil, subsoil, and bedrock below. Different types of soil like sand, silt, and clay are determined by the size of particles. Loam is an ideal soil made of a mixture of these. The document emphasizes the importance of protecting soil as a vital natural resource.
How do we use air & water
This document discusses different types of water resources and how water is treated and distributed for human use. It explains that there are two main types of water - fresh water found in rivers, lakes, glaciers etc. and salt water found in oceans. It then outlines several key steps in treating water from rivers and lakes, such as allowing solids to settle, filtering through layers of sand and gravel, adding chemicals to kill harmful organisms, and pumping the clean water for distribution.
Presentation1
Natural disasters and diseases can change environments and affect living organisms. Floods occur when heavy rain falls in a short period, covering land with water, while droughts are long periods without rain that can dry up rivers and lakes, increasing wildfire risks that damage plant and animal habitats. Diseases from mold, bacteria, and mildew also easily spread in environments and harm living things, with one infected tree having the potential to destroy an entire forest.
Plants needs
Plants need five things to survive and grow: oxygen from the air, water, nutrients found in soil, space to grow freely, and sunlight. Fruits were once living parts of plants but become non-living when picked after ripening.
Adaptation
Organisms adapt traits that help them survive in their environments. Some examples of adaptations include camouflage, mimicry, nocturnal behavior, hibernation, and migration. Camouflage allows animals to blend into their surroundings and hide from predators or to ambush prey. Mimicry enables some animals to resemble other organisms for protection. Nocturnal habits, hibernation, and migration are ways animals adapt to changes or shortages in their environments like weather changes or lack of food sources. Plants also exhibit adaptations like deep roots that help them survive in difficult conditions.
Volume
Liquids and gases take the shape of their container, unlike solids which do not. Volume is defined as the space occupied by matter, and can be measured using tools like measuring cups. Common units for measuring volume include liters and milliliters.
How do ecosystems compare
The document compares different ecosystems by describing their climates and key characteristics. Tropical rainforests have hot, wet climates all year and contain the greatest diversity of plants and animals. Temperate forests' climates change with warm summers and cold winters, and they receive less rain than rainforests. Wetlands are covered in water most of the year, found along rivers and coasts, and help absorb flood waters and cleanse dirty water. Oceans are the largest ecosystem and most living things inhabit the sunlit, shallow areas near the surface.
Food chains and food webs
Food chains and food webs show how energy passes from one organism to another as they eat each other. A food chain tracks the flow of energy starting with a plant that gets its energy from the sun, then to an animal that eats the plant, then another animal that eats the first animal. A food web is more complex, showing that organisms can be part of multiple food chains as some animals eat different plants and other animals.
Herbivores, carnivores and omnivores
This document discusses three categories of animals based on their diets: herbivores, which eat only plants; carnivores, which eat only meat; and omnivores, which eat both plants and meat. Herbivores include deer, rabbits, elephants, turtles, monkeys and giraffes. Carnivores include lions, crocodiles, snakes and eagles. Omnivores include bears, raccoons, pigs, and humans.
Ecosystem
An ecosystem is a place where living and non-living things interact, and can exist in various environments from wet to dry and small to large. In an ecosystem, living things depend on each other and non-living things like water, soil and sunlight. Producers like plants make their own food through photosynthesis, while consumers like animals obtain food by eating other organisms, and decomposers like worms break down dead plants and animals and return nutrients to the soil.
Habitat 180115095217
This document discusses habitats and the different animals that live in each one. It explains that a habitat provides all the needs for animals to survive, including food, water and shelter. It then identifies the five main habitats as ocean, forest, desert, grasslands, and Antarctica, and provides some example animals for each one. The habitats differ in their characteristics such as being wet or dry, hot or cold, containing trees, grass or snow.
Frog life cycle
The frog life cycle consists of 5 stages - eggs are laid in water, tadpoles hatch with gills and swim, tadpoles grow legs and lungs and become young frogs, young frogs resemble adult frogs and live on land, frogs undergo complete metamorphosis as each stage looks physically different.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.

Applied Science: Thermodynamics, Laws & Methodology.pdf
When I was asked to give a companion lecture in support of ‘The Philosophy of Science’ (https://shorturl.at/4pUXz) I decided not to walk through the detail of the many methodologies in order of use. Instead, I chose to employ a long standing, and ongoing, scientific development as an exemplar. And so, I chose the ever evolving story of Thermodynamics as a scientific investigation at its best.
Conducted over a period of >200 years, Thermodynamics R&D, and application, benefitted from the highest levels of professionalism, collaboration, and technical thoroughness. New layers of application, methodology, and practice were made possible by the progressive advance of technology. In turn, this has seen measurement and modelling accuracy continually improved at a micro and macro level.
Perhaps most importantly, Thermodynamics rapidly became a primary tool in the advance of applied science/engineering/technology, spanning micro-tech, to aerospace and cosmology. I can think of no better a story to illustrate the breadth of scientific methodologies and applications at their best.

Immersive Learning That Works: Research Grounding and Paths Forward
We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.

The debris of the ‘last major merger’ is dynamically young
The Milky Way’s (MW) inner stellar halo contains an [Fe/H]-rich component with highly eccentric orbits, often referred to as the
‘last major merger.’ Hypotheses for the origin of this component include Gaia-Sausage/Enceladus (GSE), where the progenitor
collided with the MW proto-disc 8–11 Gyr ago, and the Virgo Radial Merger (VRM), where the progenitor collided with the
MW disc within the last 3 Gyr. These two scenarios make different predictions about observable structure in local phase space,
because the morphology of debris depends on how long it has had to phase mix. The recently identified phase-space folds in Gaia
DR3 have positive caustic velocities, making them fundamentally different than the phase-mixed chevrons found in simulations
at late times. Roughly 20 per cent of the stars in the prograde local stellar halo are associated with the observed caustics. Based
on a simple phase-mixing model, the observed number of caustics are consistent with a merger that occurred 1–2 Gyr ago.
We also compare the observed phase-space distribution to FIRE-2 Latte simulations of GSE-like mergers, using a quantitative
measurement of phase mixing (2D causticality). The observed local phase-space distribution best matches the simulated data
1–2 Gyr after collision, and certainly not later than 3 Gyr. This is further evidence that the progenitor of the ‘last major merger’
did not collide with the MW proto-disc at early times, as is thought for the GSE, but instead collided with the MW disc within
the last few Gyr, consistent with the body of work surrounding the VRM.
