What layer of the Earth do we walk on?
We walk on the outermost layer called the crust.
200
What happens when pieces of sediment are compacted and glued together?
They form sedimentary rock
300
What type of rock contains fossils?
Sedimentary rock
300
What are two results of a convergent boundary?
A volcano or a mountain
300
What layer of the Earth is the thickest?
The mantle
300
What happens when magma or lava cools and hardens?
It forms igneous rock
400
What is one example of an igneous rock?

400
Where do divergent boundaries usually occur?
In the ocean
400
What are the innermost layers mostly composed of?
Iron and nickel
400
How are metamorphic rocks made?
When pressure and heat is applied to an igneous or sedimentary rock.
500
What are two things you should look for when identifying rocks?
2 of the following: composition (what it's made of), grain size, textural features, color ,or the presence of fossils
500
What causes the tectonic plates to move?
Earth's heat energy
500
What two things increase as you approach the center of the earth?
Temperature and pressure
500
What is the difference between weathering and erosion?
Weathering is the process of breaking down rock because of weather. Erosion is removing rock by wind, ice, running water, and waves.
