Earth's Interior and Plate Tectonics Chapter 1

How do geologists obtain indirect evidence about Earth’s interior?

• By digging deep wells into the mantle

• By using telescopes to observe the Earth's core

• By studying seismic waves and rock samples

• By sending robotic probes into the Earth

Which of the following correctly lists the layers of Earth from the surface to the center?

• Crust, outer core, mantle, inner core

• Crust, mantle, outer core, inner core

• Mantle, crust, inner core, outer core

• Crust, inner core, mantle, outer core

As you travel deeper into Earth, what happens to temperature and pressure?

• Temperature decreases, pressure increases

• Both temperature and pressure increase

• Temperature increases, pressure decreases

• Both temperature and pressure stay the same

Which of the following is NOT a method of heat transfer?

• Radiation

• Conduction

• Condensation

• Convection

In which layer of Earth’s interior do convection currents occur?

• Crust

• Mantle

• Outer Core

• Inner Core

What is Wegener’s theory called?

• Plate Tectonics

• Continental Drift

• Subduction Theory

• Ocean Expansion

What was Pangaea?

• A deep-sea trench

• A type of volcanic eruption

• A supercontinent that existed millions of years ago

• A layer of Earth’s atmosphere

Which of the following was NOT part of Wegener’s evidence for continental drift?

• Matching mountain ranges on different continents

• Similar fossils found on continents now far apart

• Ice sheets covering the entire Earth

• Evidence of tropical plants in Antarctica

Why was Wegener’s theory initially rejected?

• He lacked evidence of past climates

• He could not explain the force that moved continents

• There were no similar fossils on different continents

• The continents never actually moved

What process creates new ocean floor at mid-ocean ridges?

• Subduction

• Sea-floor spreading

• Earthquake activity

• Mantle cooling
