metamorphic
What are fossils, and in what type of rock can they be found?
Fossils are plants, animals and insects, which lived thousands of years ago and have died and been trapped and buried in sedimentary rock.
Rocks move and change on the surface of the earth because of _________and__________.
weathering, erosion
Crystals are formed when Igneous rocks are cooled________.
slowly
Rocks move and change over time because of _______and_________inside the earth.
heat, pressure
Name,and draw, in order, from top to bottom, the three layers of rocks found on and in the earth.
1. Igneous (found on the earth's surface as well as in magma),
2. Sedimentary,
3. Metamorphic

Which two layers of the earth are composed mostly of rocky material ?
