Crust, mantle, core
How is continental crust different from oceanic crust?
Oceanic has twice as much iron, calcium, and magnesium as Continental.
What are the five physical layers of earth?
lithosphere, asthenosphere, mesosphere, outer core, inner core
What is the definition of plate tectonics?

New landforms, climate changes, fertile soil
What is the difference between the inner planets and the outer planets?
The inner planets are solid, rocky, small, close together, and they have less moons. Outer planets are larger, farther from the sun, far apart, and have many moons.
What order are the planet in?
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto.
What are the two differences between rotation and revolution?
Rotation is the spin and the revolution is the time period.
How is a asteroid different from meteoroid?
Meteoroids are smaller than asteroids.
What is a comet?
A small body of rock and cosmic dust that orbits the sun giving of gas and dust as it gets closer to the sun.

Which of the following is a renewable resource? Coal, natural gas, petroleum, or freshwater.
What is strata?
Layers in sedimentary rocks.
What kind of deformation leads to earthquakes?
The deep interior of the earth can be mapped by using (Blank)?
A person who studies earthquakes is called a (Blank)?
What is the area where two tectonic plates meet called?
Some scientist Refer to (Blank) as dirty snowballs because they are composed of ice rock and cosmic dust.
What can a scientist learn about a star from it's spectrum?
Why is the planet Uranus considered a gas giant?
Because it has a deep massive atmosphere.
