What did the white sedimentary rock say when they needed some time alone?

What is the molten rock just below the Earth's crust called after it breaks through to the surface?

I lava you sooooooo much!
What has to happen to molten rock that comes from a volcano for it to form igneous rocks?
it has to cool and harden
What has to happen to layers of sediment for them to form sedimentary rock?
What two forces cause other types of rocks to transform into metamorphic rock?
heat and pressure
Which of the three rock types formed first in Earth's geologic history?
igneous rock, from volcanoes
Why wasn't the metamorphic rock comedian very funny?
They were under too much pressure.

Name one of the two processes that break off sediment from existing rocks and mountains...
weathering and erosion
Why are there fossils at the top of the Sandia Mountains?
Animals and plants died millions of years ago, when the Sandias were at the bottom of an ocean, embedded in sedimentary rock. Then, metamorphic heat and pressure lifted the Sandia Mountains thousands of feet into the air. The fossils rose up with the rock itself.
