The document summarizes the history of Earth based on geological evidence. Scientists have determined that early Earth had a different atmosphere composed of gases from volcanic eruptions. Over millions of years, these gases and precipitation formed oceans. Green plants then produced oxygen through photosynthesis, changing the atmosphere. Scientists use various geological features like rock layers, fossils, and radioactive dating to determine the sequence of events in Earth's history and develop a geological timescale.
This document discusses the exploration and discovery of planets, moons, and dwarf planets within our solar system. It describes findings such as the presence of liquid methane on Titan, Saturn's largest moon, and sedimentary rocks on Mars that indicate ancient water. It outlines plans for human colonization of Mars by 2027 through the Mars One program. Additionally, it provides details on dwarf planets such as Ceres, Haumea, Makemake, and Eris, and discusses the first exoplanet discovered in the habitable zone of a sun-like star, Kepler-22b.
The document discusses the causes of car collisions in Canada in 2012. It identifies the main causes as equipment failure, roadway design and maintenance issues, and driver behavior. Equipment failures like issues with brakes, tires, and suspension can be reduced through regular inspections. Roadway design problems involve hazards, surfaces, traffic controls, and signs, which transportation agencies aim to improve. However, over 95% of accidents involve unsafe driver behavior such as distracted driving, fatigue, drunk driving, speeding, and aggression. Changing driver behavior is key to reducing collisions.
The document provides information about various natural disasters including earthquakes, tornadoes, landslides, volcanoes, floods, droughts, hurricanes, famines, tsunamis, forest fires and cyclones. It defines each disaster and provides some key details and examples of significant events for some of the disasters.
Light is electromagnetic radiation that stimulates sight and makes objects visible. It is classified based on how it interacts with different materials. Transparent materials allow light to pass through clearly, translucent materials allow some light to pass through, and opaque materials do not allow any light to pass through. The visible light spectrum refers to the portion of the electromagnetic spectrum detectable by the human eye, ranging from infrared to violet. Within this spectrum, colors are arranged from long to short wavelengths as red, orange, yellow, green, blue, and violet.
Light travels in straight lines. Shadows are formed when light is blocked by an object. The size and shape of shadows can change depending on the position of the light source and object. Reflection of light allows us to see objects when light bounces off their surfaces and into our eyes. Common examples of reflection include mirrors, water surfaces, and other shiny materials.
Until we know that large wind turbines/mills to generate electricity. But the technology advanced such that these wind turbines came to our home for our domestical use. In this ppt I discussed about new small residential wind turbines by which we can reduce our electrical bills and more. Have a look!
This presentation introduces the characteristics of light and the electromagnetic spectrum. It discusses the different types of electromagnetic waves including their frequencies and wavelengths. It describes the parts of a wave like amplitude, frequency, period, and wavelength. It explains that light travels at a finite speed of 299,792,458 meters per second. It also covers how the brightness of light decreases with the inverse square of the distance from the source.

The document discusses momentum and impulse, which are important factors in understanding how force affects the motion of objects. It states that more force is needed to quickly stop objects that have greater momentum, whether due to higher mass or velocity. Momentum is defined as the product of an object's mass and velocity, and can change if either variable changes or if a net external force is applied. Impulse is equal to the change in an object's momentum due to a force applied over a time interval. Applying a force over a longer period of time results in the same change in momentum but with a smaller average force.
This document discusses projectile motion, beginning with an overview of the objectives and definitions. It explains that a projectile experiences only gravity and air resistance, and its motion can be analyzed as independent vertical and horizontal components. Horizontal projectiles follow the simplest case where velocity is constant horizontally but follows parabolic free fall vertically. Non-horizontal projectiles require calculating initial velocity components and analyzing changes in vertical velocity over time. Solving projectile motion problems generally involves drawing diagrams, choosing a coordinate system, and applying the independent kinematic equations along each axis. Air resistance decreases a projectile's range from the ideal parabolic trajectory.
This document defines projectile motion and its key components. It discusses:
1) A projectile is any object that continues to move under the influence of gravity alone after being thrown or dropped. Projectile motion follows a parabolic path due to constant horizontal velocity and changing vertical velocity from gravity.
2) Types of projectile motion include horizontal, vertical, and parabolic. Examples are cannonballs and objects thrown from moving vehicles.
3) Derivations show the relationships between initial velocity, acceleration, velocity, displacement, maximum height, range, launch angle, and time for projectile motion. The two main factors affecting projectile motion are the initial launch angle and velocity.
The document summarizes key events in Earth's history from the formation of the solar system to the present. It describes the origin of life beginning with simple prokaryotes over 3 billion years ago. The first complex eukaryotic cells emerged around 1.7 billion years ago, followed by multicellular organisms over 700 million years ago. The development of land plants and animals is outlined through the Precambrian, Paleozoic, Mesozoic and Cenozoic eras, along with changing climates and configurations of the Earth's continents and oceans. Absolute and relative dating methods are also summarized that are used to determine the age of geological features and fossils.
The document provides information about various natural disasters including avalanches, earthquakes, hurricanes, landslides, thunderstorms, tornados, tsunamis, and volcanoes. For each type of disaster, it describes what causes it and includes one or more relevant images. It also provides additional resources and links for further information. The document was written by Ben Darin, a 19-year-old studying elementary education, who included his contact information.
Light travels in straight lines and very fast, faster than sound. We see objects because they reflect light into our eyes, while shadows are formed when light is blocked. There are two main types of reflection - specular reflection off smooth surfaces like mirrors, and diffuse reflection off rough surfaces. The law of reflection states that the incident ray, reflected ray, and normal to the surface all lie in the same plane, with the angle of incidence equaling the angle of reflection.
The document introduces the concept of linear momentum, which is defined as the product of an object's mass and velocity. Linear momentum depends on both the mass and speed of an object. The linear momentum of a system remains conserved as long as there are no external forces acting, according to the law of conservation of linear momentum. Collisions between objects also conserve linear momentum, with the total momentum before a collision equaling the total momentum after.
This document discusses impulse, momentum, and collisions in physics. It defines impulse as equal to momentum and discusses how impulse is the area under a force-time graph. Collisions are analyzed using the principles that momentum is conserved unless an external force acts, and that equal and opposite forces during a collision lead to equal impulses and momentums between colliding objects. Several examples calculate momentum and velocity values before and after collisions.
The document discusses the four main systems that make up Earth: the atmosphere, hydrosphere, biosphere, and geosphere. It focuses on the hydrosphere, explaining that water covers 70% of the Earth's surface and is essential for life. It then describes the water cycle, in which water is in constant motion between the oceans, atmosphere, and land via evaporation, condensation, precipitation, and collection.
Light is necessary for sight and interacts with the eyes and brain to allow us to see. Reflection occurs when light changes direction at the interface between two different media, following the law that the angle of incidence equals the angle of reflection. Refraction is when a light ray changes direction and speed as it passes from one medium to another due to a change in density.
This document summarizes the key characteristics that indicate the planet Earth is capable of supporting life. It examines Earth's galactic neighborhood, its G2 class star the Sun, its location within the habitable zone allowing liquid water, its size and composition as a terrestrial planet, its magnetic field and atmosphere, and its nearly circular orbit and rotational properties including axial tilt that produces seasons. All of these factors analyzed together demonstrate how Earth meets the known criteria to potentially support life.
The document discusses several key properties of light, including:
- Reflection - Light bounces off surfaces at the same angle it hits.
- Refraction - Light bends as it passes from one medium to another, changing speed. The degree of bending depends on the medium's index of refraction.
- Interference - When two light waves meet, they can constructively or destructively interfere based on how their crests and troughs align.
It explores light's dual nature as both a wave and particle, demonstrated through experiments like Young's double-slit experiment showing light's wave-like interference patterns, and the photoelectric effect showing its particulate properties.
Light is an electromagnetic wave that consists of oscillating electric and magnetic fields and can travel through space. It spreads in straight lines and carries energy. Light sources such as the sun emit light, while objects that do not emit light themselves are called dark bodies. When light hits surfaces, it can be reflected, absorbed, or pass through depending on whether the surface is opaque, translucent, or transparent. The law of reflection states that the angle of incidence equals the angle of reflection. Shadows form when light rays are blocked by an opaque object.
This document discusses natural disasters, including what defines a natural disaster versus a natural hazard. It then lists and provides brief descriptions of common natural disasters such as earthquakes, avalanches, landslides, floods, tsunamis, blizzards, droughts, and wildfires. For earthquakes specifically, it outlines what to do before, during, and after an earthquake occurs. It also notes that earthquakes are among the most likely natural disasters to occur in Chile and lists some active volcanoes in the country.
Light is part of the electromagnetic spectrum that is visible to the human eye. It travels in straight lines called rays. Reflection is when light bounces off a surface, following the laws that the angle of incidence equals the angle of reflection and that the incident, normal, and reflected rays lie in the same plane. Refraction is when light changes speed and direction as it passes from one medium to another due to the different refractive indices, following Snell's law. Total internal reflection occurs when light cannot pass from an optically denser medium to a less dense one if the angle of incidence exceeds the critical angle.
This document discusses key properties of light including reflection, refraction, diffraction, and interference. Reflection occurs when light bounces off a surface, following the law that the angle of incidence equals the angle of reflection. Refraction is the bending of light when passing from one medium to another at different speeds. Diffraction causes light to bend around barriers depending on the wavelength and barrier size. Interference results from the interaction of crests and troughs of light waves, producing constructive or destructive interference.
This document discusses the concept of disaster risk management. It begins by showing pictures of recent disasters in India to illustrate the risks faced. It then defines key terms like hazard, vulnerability, capacity and disaster risk. Disaster risk is explained as being a function of hazard x vulnerability - capacity. Recent examples of disasters across India from 2011-2012 are provided, including earthquakes, floods, cyclones and landslides. The document emphasizes that communities must be aware and prepared in order to minimize losses from disasters. It outlines the disaster management cycle and different approaches like emergency management and disaster risk management.
Disaster management involves preparing for, responding to, and recovering from disasters. A disaster is defined as any event that causes damage, loss of life, or deterioration of health beyond the capacity of local communities. Disaster nursing focuses on meeting physical and emotional needs resulting from disasters. Disasters can be natural or man-made, and affect communities in different ways depending on factors like speed of onset and duration. The phases of disaster management include preparedness, response, rehabilitation, and mitigation. Nurses play an important role in all phases through activities like community assessment, triage, disease surveillance, and psychological support.

Editor's Notes
what you see here is an image taken by the hubble telescope we see stars and galaxies yet, science now tells us, that we started with nothing...? today I will review the big bang theory I will explain how it is modified i will explain how being uncertain is a science, and that uncertainty/confusion/randomness made nothing useful
put it all together.. timeline of the universe, concentric circles.
