• fossils found on different continents

• fit of the continents

• rock type similarities

• ancient glacial features

• the mechanism for how the continents moved

We can use the order of layers of rock to determine their relative ages. This ability is based on which of the following laws?

• Law that states if rock is undisturbed, the oldest layers will be on the bottom and the youngest layers will be on the top. (law of superposition)

• Law that states that sedimentary rock is deposited horizontally. (law of original horizontality)

• Law that states matter cannot be created nor destroyed. (law of conservation of matter)

• Law that states energy cannot be created nor destroyed. (law of conservation of energy)

What principle of geology states that sedimentary rocks are deposited horizontally or nearly horizontally?

• cross-cutting relationships

• original horizontality

• uniformitarianism

• superposition

If an index fossil known to be 300 million years old is found in a layer of rock, which of the following is the best conclusion based on this find?

• the other fossils in that layer are about 500 million years old.

• the other fossils in that layer are about 100 million years old.

• the other fossils in that layer are about 300 million years old.

• the other fossils in that layer are all different ages.

Rock clues were used to support the theory of continental drift because

• Similar rock structures were found on different continents.

• The Appalachian Mountains looked completely different than the mountains on Greenland.

• Fossils were found in the rocks.

Why do we use analogies like the length of a hallway or a 24 hour clock when discussing geologic time?

• Timescales involved in Earth's history cannot be described without an analogy.

• Timescales involved in Earth's history are immensely shorter than the lifetime of a human.

• Timescales involved in Earth's history are immensely longer than the lifetime of a human.

• Timescales involved in Earth's history are very simple to understand and therefore it is easy to construct a scaled analogy to explain them.

The PROCESS by which molten material adds new oceanic crust to the ocean floor is called

• subduction

• continental drift

• seafloor spreading

• convergence
