Foss Earth History Inv. 3-4 Review

Two students are exploring a creek in their neighborhood. The students hope to find some fossils along the way. What kinds of rocks should the students look for on their hike, and why should they look for those kinds of rock?

Answer: The students should look for (a)   rocks like shale, limestone, and sandstone. Fossils form when they are quickly covered by sediments in a basin.

Two students are exploring a creek in their neighborhood. Continuing along the creek, they find some pieces of white sandy rock in the creek. They drip hydrochloric acid on that rock. The rock does not fizz.

Select Yes if the process likely formed the rocks in the creek; select No if the process did not contribute to the rock formation.

Process: Deposition

• Yes

• No

Which statement best describes the principle of uniformitarianism?

• • Deposition occurs faster today than it did in ancient environments.

• • Rocks form by the same processes today as in the past.

• • Weathering and erosion can be fast or slow, depending on the type of rock.

• • Earth's geological features were formed by a few catastrophic events.

Why is uniformitarianism an important principle to consider when making inferences about how Earth's geology has changed over millions of years?

Answer: Uniformitarianism says that the processes that shape Earth are the (a)   throughout time. That means if we see a process shaping Earth today we can assume the same process shaped Earth in the past and will continue to shape Earth in the future.
