Geosphere Test Review

Why are fossils rarely found in metamorphic or igneous rock?

• Chemicals toxic to living things are released while forming

• Heat/Pressure are great enough to destroy fossils inside

• Decay of radioactive isotopes change the fossils

• Magnetic fields found where rocks form keep organisms away

Granite is an igneous rock. Which describes what happen to it after it is weathered?

What has to occur to change igneous rock to sediment?

• Weathering and Erosion

• heat and pressure

• cooling and solidification

• cementation and compaction

Which even will most likely occur at point A?

• an eroded mountain will rise

• Magma will form new crust

• A freshwater lake will develop

• Rivers will form a canyon

Which movement of tectonic plates caused a rift valley to form?
