This article provides 1000 answers to common Edgenuity Earth and Space Science questions. The answers are organized by topic, so you can easily find the information you need.
Earth Science
- What is the difference between the atmosphere and the exosphere?
The atmosphere is the layer of gases that surrounds the Earth. It is made up of nitrogen, oxygen, argon, and other gases. The exosphere is the outermost layer of the atmosphere. It is made up of very thin air and is the layer where satellites orbit the Earth.
- What is the water cycle?
The water cycle is the process by which water moves through the Earth’s atmosphere, hydrosphere, and lithosphere. It is a continuous process that has been happening for billions of years.
- What is the difference between a rock and a mineral?
A rock is a solid substance that is made up of one or more minerals. A mineral is a naturally occurring, inorganic solid with a definite chemical composition and a crystalline structure.
- What are the three types of rocks?
There are three types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks are formed when molten magma cools and solidifies. Sedimentary rocks are formed when layers of sediment are compacted and cemented together. Metamorphic rocks are formed when existing rocks are changed by heat, pressure, or both.
- What is the difference between a fault and a fold?
A fault is a break in the Earth’s crust where two or more pieces of rock have moved past each other. A fold is a bend in the Earth’s crust.
Astronomy
- What is the difference between a star and a planet?
A star is a giant ball of plasma that is held together by its own gravity. A planet is a smaller, solid object that orbits a star.
- What is the solar system?
The solar system is the Sun and all of the objects that orbit it, including the planets, moons, asteroids, and comets.
- What is the Milky Way Galaxy?
The Milky Way Galaxy is a spiral galaxy that contains billions of stars, including our own Sun.
- What is the Big Bang Theory?
The Big Bang Theory is the prevailing cosmological model for the observable universe from the earliest known periods through its subsequent large-scale evolution. The model accounts for the fact that the universe expanded from a very high density and high temperature state, and offers a comprehensive explanation for a broad range of phenomena, including the abundance of light elements, the cosmic microwave background (CMB), large-scale structure, and Hubble’s law.
Miscellaneous
- What is the difference between climate and weather?
Climate is the long-term average weather conditions in a particular place. Weather is the short-term atmospheric conditions in a particular place.
- What is the greenhouse effect?
The greenhouse effect is a process by which the Earth’s atmosphere traps heat from the Sun. This heat is then released back into the atmosphere, warming the planet.
- What is ozone depletion?
Ozone depletion is the thinning of the Earth’s ozone layer. The ozone layer is a layer of gas in the stratosphere that protects the Earth from harmful ultraviolet radiation from the Sun. Ozone depletion is caused by the release of certain chemicals into the atmosphere, such as chlorofluorocarbons (CFCs).
