What is the upper mantle made up of?
Rock that is fluid and can move
What is Global Warming?
An increase in Earths Atmosphere because of the Green House Effect.
Which sphere contains all the planets living things?

What is Earth System Science?
The study of Earths four spheres and how they interact with the Earth and each other.
Where are Ocean Ridges located?
Between two tectonic plates moving apart, known as divergent Boundary.
How are igneous rocks formed?
They form from cooling of lava
Why are fossil fuels Non-Renewable?

Lava
what is the expulsion of liquids from pores, and the cementation of the pre-existing rock.
Sedimentary rock
What sphere contains all the solid, liquid, and gaseous water of the planet?
Hydrosphere
How does wind create all the ocean currents?

what is layering that occurs when rock is compressed along one axis during recrystallization.
Metamorphic Rock
what is the layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body?
Atmosphere
Why don't the oceans freeze?
seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. At least 15 percent of the ocean is covered by sea ice some part of the year.
How do scientists identify plate boundaries?
By studying data from earthquakes
