Earth's Structure and Plate Tectonics

Front

What process does the figure show occurring in the mantle?

Back

Hot rock expands, becomes less dense, and rises toward the surface of Earth.

Front

Earth’s temperature increases with depth. What results from the motion of materials caused by high temperatures in Earth’s mantle?

Back

earthquakes and volcanoes

Front

Evelyn is making a model of Earth to show how the physical layers correspond to the compositional layers. What should Evelyn show in her model?

Back

The physical layers of the inner core and outer core form a single compositional layer.

Front

Which part of the mantle is also part of the lithosphere?

Back

the rigid upper part

Front

Which process led to the formation of Mount Everest when two tectonic plates collided?

Back

pushed up or uplift

Front

Classify basalt and granite based on their formation: Basalt forms when lava cools on Earth’s surface. Granite forms when magma cools within the Earth.

Back

Basalt and granite are both igneous rocks.

Front

What did the geologist use to determine the relative ages of the rocks? The bottom layer is the oldest, and the top layer is the youngest.

Back

the law of superposition

Front

What is the process that shows the relationship between carbon-14 and nitrogen-14?

Back

radioactive decay

Front

Fossils of the same plants and animal species have been found on continents separated by the Atlantic Ocean. What does this observation support?

Back

The continents that are now separated by the Atlantic Ocean once formed a single landmass.

Front

The figure shows a process that takes place on the ocean floor.
Which of the following is most likely to result from the process shown in this figure? Options: petrification, trace fossil formation, continents moving, glacial melting

Back

continents moving
