|
What are the three types of rock? |
Sedimentary, Igneous, Metamorphic |
|
|
What are Sedimentary rocks? |
Fragments of sand, shells, and particles that come together and harden |
|
|
In which rocks are most fossils found? |
In Sedimentary rocks |

|
How do Metamorphic rocks form? |
They form under the Earth's surface when the pressure pushing down on earth brings the minerals together and harden over time. |
