Plate Tectonics and Earth's Surface Features

The figure shows part of what scientists think is happening in Earth’s mantle.

What process does the figure show occurring in the mantle?

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

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

• Hot rock becomes less dense and moves towards the outer core.

• Hot rock becomes more dense and moves towards the lithosphere.

Fossils of the same plants and animal species have been found on continents that are separated by the Atlantic Ocean. Which of the following statements does this observation support?

• These animals and plants crossed the Atlantic Ocean.

• The Atlantic Ocean was once a large body of freshwater.

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

• The continents that are now separated by the Atlantic Ocean have the same kinds of organisms today as they did millions of years ago.

Earth’s surface features slowly change over time. For example, sharp, jagged mountain ranges become lower and more rounded over time. What factor(s) is responsible for this change in their shape?

• weathering and erosion

• depostion

• movement of continents

• collisions between continental plates

Subduction occurs when one plate slides beneath another plate. The figure below shows the process of subduction. Notice that the oceanic plate slides beneath the continental plate.

What happens when the crustal plates move as shown in the figure?

• An ocean forms.

• Volcanic mountain ranges form.

• Sea-floor spreading occurs as the oceanic plate moves.

• A transform boundary forms where the subduction occurs.

• seafloor spreading

• mountain range formation

• formation of an ocean trench
