Weathering is
breaking down of rocks

the way the Earth constantly recycles rocks
the rock cycle
Similarity of metamorphic and sedimentary rocks
pressure
Plate boundary that forms most volcanoes
convergent
Iowa hundreds of million of years ago
Covered in a sea
Pangea broke apart
movement of plate tectonics
Erosion is
carrying away rocks and minerals
Intrusive igneous rocks cool here
underneath the surface of the Earth
Plate boundary that forms a trench
The reason Iowa has a lot of limestone

continents fit together, similar animal remains, similar rocks
