26
Normal faults
Occur when a body of rock is spilt apart
27
Reverse faults occur when
Two bodies of rock are pushed together
28
Igneous rocks form from
Melted rocks witch have hardened
29
Metamorphic rocks are rocks
That have been changed due to tremendous heat.
30
Sedimentary rocks can form
Can form from biologic accumulation or cementation of pre-exiting pieces of rock
31
Shield volcanos are
Made of lava and have a broad low profile
32
Cinder cones are
Made of larger material blown from larger material blown from the volcano
33
Composite cones are
Made of pyroclastic material and lava
34
The crust and mantle are composed of
Silicates
35
