Earth Sci Spring Final Study Guide 2025

What does the law of superposition tell us?

• that rocks are very old

• that rock layers are older on the bottom and younger at the top

• that rocks can become deformed by pressure

• that rocks are about 4 billion years old

The principal of Original Horizontality states that......

• layers of the Earth are made of granite

• sediments are only deposited under the ocean

• layers of sediment are generally deposited in a horizontal position

• layers of sediments are usually deposited in vertical positions

The principal of Cross Cutting Relationships tells us that......

• rock that cuts across established layers is younger than the rocks it is cutting through

• rocks that cut across layers are older than the layers they are cutting through

• rocks are not able to cut across established rock layers because they are too old

• rocks can not contain fossils in the layers that are cut

In rock formations, what are inclusions?

• rocks that are surrounded by older rock formations

• rocks that break off during an intrusion and are embedded in younger rocks

• sediments that have fossils included

• rocks that are mostly granite type rocks

What type of rock do we find fossils embedded?

• granite

• igneous

• sedimentary

• metamorphic

How can we use the law of super position to determine the relative age of a fossil?

• fossils that are found in lower sedimentary rock layers are older than fossils that are found in layers that are above those layers

• the law of superposition can not be used for determining the age of fossils

• fossils that are found in layers of sedimentary rocks are usually older than the rock layers they are found in

• fossils that are found in upper layers of sedimentary rocks are the oldest of all fossils
