Scientists recently discovered that rocks collected from the Franklin Mountains in West Tests and rocks collected from mountains in eastern Antarctica were exactly the same age. Further research showed that the rocks were chemically and geologically the same and came from the same magma source. This discovery provides evidence of--
coastal erosion
plate tectonics
ocean currents
glacial melting
Which statement best describes the geologic process that is most likely responsible for the formation of mountains?
They are along a transform plate boundary that is no longer active, so erosion is creating deep valleys.
They are along a transform plate boundary in which plates are currently moving side by side, causing earthquakes and faults
They are along a plate boundary in which plates are currently converging, causing uplift and steep slopes.
They are along a plate boundary in which plates diverged in the distance past, allowing new rock to build up.
A mid-ocean RIDGE is located at the boundary of two tectonic plates. Which diagram correctly models the relative plate motion on each side of a mid ocean ridge?
Rift valleys can from when fractures in Earth's crust widen. The valley walls slowly move at a rate of only a few millimeters a year. Which of these best describes the type of tectonic activity that forms rift valleys?
Rift valleys from where a continental plate moves under an oceanic plate
Rift valleys form where a plate slides horizontally past another plate
Rift valleys from where two plates move away from each other.
Rift valleys form where an oceanic plate moves under another oceanic plate.

The satellite image below shows a ship channel between South Padre Island and Boca Chica beach on South Texas.

The ship channel would become deeper, and the island would move west toward the mainland.
The ship channel would become shallower, and the beach would become narrower.
The ship channel would become narrower, and the island would become completely covered with water.
The ship channel would become wider, and the island would sink into the Gulf of Mexico.

This picture 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 on 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

be flat and then go up a steep slope
go down a steep slope and then become flatter
