The document contains answers to questions about plate tectonics and the movement of lithospheric plates. It explains that the stripes on the diagram represent rocks with normal and reverse magnetic polarities. The middle split represents the mid-ocean ridge, where seafloor spreading occurs and new crust is formed. The mid-ocean ridge is where the forces that push the lithospheric plates originate from. Magma rises from below the crust at the ridge and hardens to form new seafloor that moves away from the ridge. Subduction occurs at the side slits. The Earth does not get larger as plates move apart because as new crust is created at ridges, old crust is destroyed elsewhere.

This document provides an overview of the Earth's interior structure based on seismic wave evidence. It discusses how seismic waves like P-waves and S-waves travel through different layers, revealing details about the composition and state of those layers. The existence of an S-wave shadow zone indicated the inner core is solid, while P-wave refraction showed bending consistent with a liquid outer core. Later discoveries of an inner core within the outer liquid core helped establish the current model of a solid inner core within a liquid outer core surrounded by the mantle and crust.

2 Earth_and_Life_Science-Earth Subsystem.pptx
The document discusses the four subsystems that make up the Earth:
1. Atmosphere - The gaseous layer composed primarily of nitrogen and oxygen that supports life.
2. Biosphere - The zone where all life exists on land, in water, and in the sea.
3. Geosphere - The solid portion of the Earth consisting of the core, mantle, and crust.
4. Hydrosphere - The water portion of the Earth found in oceans, glaciers, and the atmosphere, comprising 71% of the Earth's surface.
Matter and energy flow continuously between these four interconnected subsystems.
Q1W1 4 SUBSYSTEMS.pptx
The document discusses the four subsystems of Earth: the atmosphere, biosphere, geosphere, and hydrosphere. It describes the characteristics of each subsystem and how matter and energy flow between them. The four subsystems are interconnected, as described by the John Muir quote that tugging on one subsystem affects the rest. Matter and energy flow across subsystem boundaries, with the atmosphere providing heat and energy to the geosphere and biosphere, while the biosphere receives gases, heat, sunlight and water from other subsystems.
ELS MODULE 2 PPT.pptx
Here are two examples of interactions between Earth's subsystems:
1. Volcanic eruptions (geosphere) release large amounts of gases and ash into the atmosphere. The ash and particles can serve as nuclei for formation of raindrops, influencing precipitation patterns and potentially increasing rainfall (hydrosphere). The changes in rainfall can impact plant growth and ecosystems (biosphere).
2. Photosynthesis by plants (biosphere) releases oxygen and absorbs carbon dioxide from the atmosphere. Plants also take in water and minerals from the soil (geosphere) through their roots. Transpiration by plants releases water vapor into the air (hydrosphere), influencing the water cycle and climate.
The Earth System.pptx
Earth system refers to Earth’s interacting physical, chemical, and biological processes.
The system consists of the land, oceans, atmosphere and poles.
It includes the planet’s natural cycles – the carbon, water, nitrogen, phosphorus, Sulphur and other cycles – and deep Earth processes.

Earth's Sybsystem.pptx
The document discusses the Earth's subsystems which include the cryosphere, atmosphere, hydrosphere, biosphere, and geosphere. It provides details about each subsystem, including that the atmosphere is composed of gases like nitrogen and oxygen and regulates climate. The hydrosphere includes oceans, glaciers, and water in the atmosphere. The biosphere is where all life exists in an ecosystem on land, in water, and the sea. The geosphere is the solid part of Earth, including the core, mantle, and crust. The subsystems interact with each other through the flow of matter and energy across their boundaries.
leccture 1.pptx
The document discusses the factors that make Earth habitable for life. It notes that Earth is the only planet known to support life and identifies some key characteristics, including its distance from the Sun, protective magnetic field, insulating atmosphere, and presence of water and carbon. It then describes Earth's four main subsystems - the atmosphere, geosphere, hydrosphere, and biosphere. It provides details on the layers of the atmosphere and explains how matter and energy flow between the different subsystems in processes like the carbon cycle.
Science Unit 4 (Glencoe Red 2002)
The document summarizes key information about Earth's atmosphere:
1) Earth's atmosphere is composed of nitrogen (78%), oxygen (21%), and trace amounts of other gases like carbon dioxide and argon. It also contains water vapor, solid particles, and liquid droplets.
2) The atmosphere is divided into five main layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere - with varying temperature and air pressure profiles.
3) Air pressure decreases with increasing altitude as there are fewer gas molecules above Earth's surface to exert pressure downward. Atmospheric pressure is greater in the troposphere near Earth than in the exosphere.
Lesson 2 EARTH'S SUBSYSTEMS.pptx
The document discusses the four subsystems of Earth - the atmosphere, geosphere, hydrosphere, and biosphere. It provides details on what each subsystem consists of and its functions. The four subsystems allow Earth to sustain life through the flow of matter and energy across their boundaries. A change in one subsystem affects the others as all are interconnected.
LESSON 1.2.pptx
The document discusses the four main subsystems that make up the Earth: the atmosphere, geosphere, hydrosphere, and biosphere. It provides details on each subsystem, including the composition and layers of the atmosphere. The subsystems interact with each other through flows of matter and energy. For example, the atmosphere provides heat and energy to the geosphere while the biosphere receives gases, heat, sunlight and water from the other subsystems. This dynamic interaction between the subsystems creates a habitable environment for life on Earth.
Earth Science
The document discusses Earth science and the Earth system. It defines Earth science as the study of the Earth's interior, rocks, soil, atmosphere and oceans. It explains that Earth science today focuses on the connections between these different parts. Heat from the Earth's interior and radiation from the sun provide energy for Earth's processes. The Earth system consists of four major interconnected parts: the atmosphere, hydrosphere, geosphere and biosphere.
Summary 0f the earth system, origin...
The document discusses the structure and components of the Earth system. It states that the Earth can be considered a closed system that receives energy from the Sun and exchanges heat with space. It also notes that the universe is around 13.8 billion years old and the diameter of the observable universe is at least 91 billion light years. The Earth system consists of four main interacting subsystems: the lithosphere, hydrosphere, atmosphere, and biosphere. Materials cycle continuously between these subsystems, such as in the carbon, rock, and water cycles. The subsystems also receive and redistribute energy, with the main external energy source being the Sun and internal sources being radioactive decay and gravitational energy.

ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Nucleic Acid-its structural and functional complexity.
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
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.

Cytokines and their role in immune regulation.pptx
This presentation covers the content and information on "Cytokines " and their role in immune regulation .
The binding of cosmological structures by massless topological defects
Assuming spherical symmetry and weak field, it is shown that if one solves the Poisson equation or the Einstein field
equations sourced by a topological defect, i.e. a singularity of a very specific form, the result is a localized gravitational
field capable of driving flat rotation (i.e. Keplerian circular orbits at a constant speed for all radii) of test masses on a thin
spherical shell without any underlying mass. Moreover, a large-scale structure which exploits this solution by assembling
concentrically a number of such topological defects can establish a flat stellar or galactic rotation curve, and can also deflect
light in the same manner as an equipotential (isothermal) sphere. Thus, the need for dark matter or modified gravity theory is
mitigated, at least in part.
Equivariant neural networks and representation theory
Or: Beyond linear.
Abstract: Equivariant neural networks are neural networks that incorporate symmetries. The nonlinear activation functions in these networks result in interesting nonlinear equivariant maps between simple representations, and motivate the key player of this talk: piecewise linear representation theory.
