Which is not a piece of evidence that Harry Hess used to support his theory of Sea-Floor Spreading?

• pillow rocks

• drilling samples

• landforms

• magnetic stripes in sea floor

This image shows scratches in bedrock that were caused by a moving glacier. These scratches are called glacial striations. Glacial striations in the bedrock of South Africa indicate that glaciers once moved across the African continent. The presence of glaciers in the surface of Africa is evidence that ____________.

• the tectonic plate under Africa was closer to the South Pole at one time

• the equator was not always where it is currently located

• volcanoes did not exist until after faults occurred in Earth's crust

• the location of the North Pole and the South Pole changed

The San Andreas fault is a transform fault. The map below shows a student's approximation of where the fault line crosses through the United States. Students were asked to make maps predicting which way land would most likely move over thousands of years. Which map best predicts the likely movement of land along the fault line over thousands of years?

The Himalayan mountains are shown in the map. Four students were asked to identify the geologic process that caused this mountain range to form. Which student correctly identified the geologic process that formed the Himalayan mountains?

• Student 1: Two continental plates converging

• Student 2: An earthquake in a subduction zone

• Student 3: A tectonic plate moving over a hot spot

• Student 4: Movement at a transform fault boundary
