Rock cycle
What are the three different types of rocks
Sedimentary, Metamorphic and Igneous
What are rocks made out?
Sediments
How many types of plate boundaries are there?
Transform, Divergent, Convergent
At which plate boundary is new ocean crust formed
Divergent plate boundaries
How can the same mineral deposits be on different continents
They were once connected
Name the two most common types of weathering
Wind and water
How do new rocks get made?
Through magma or sedimentation.
What plate boundary forms mountains?
Convergent plate boundary
Where is the oldest Ocean crust located?
Where the ocean crust meets the continental crust
What two continents used to be connected in the past?
South American and Africa
Name the process for when larger rocks are broken down into smaller and smaller peieces
Weathering
Where is most of the new rock on earth formed
What direction do convergent plates move?
Towards each other
Why does continental crust not get recycled?
It is lighter than ocean crust
What two forces are responsible for the making metamorphic rocks?
Heat and pressure
Name some forces that change rocks into other rocks
Heat and pressure
At which plate boundary does subduction occur
Ocean, continent boundaries
No it isn't because it get recycled
How do the tectonic plates move.
Through the energy of the earth
As Magma cools to form Igneous rocks, colder temperatures cause what to happen?
Larger crystals to form
Can rocks form by sediments being squeezed together
Yes they can
At which plate boundaries do earthquakes occur most often
Transform plate boundaries
What happens to crust when it goes into a subduction zone?
It gets recycled into the earth
Does mountain formation cause earthquakes?
No it does not
