What is the lithosphere?

• The outermost layer of Earth, consisting of the crust and upper mantle

• A layer of gases surrounding the Earth

• The innermost layer of Earth, consisting of the core

• A layer of water covering the Earth's surface

How do temperature and pressure change as you go from the crust to the inner core?

• Both temperature and pressure decrease

• Temperature decreases while pressure increases

• Both temperature and pressure increase

• Temperature increases while pressure decreases

What is the definition of CONTINENTAL DRIFT?

• The gradual movement of continents across the earth's surface through geological time.

• The sudden movement of tectonic plates causing earthquakes.

• The process of mountain formation due to tectonic activity.

• The erosion of continental landmasses by natural forces.

Which of the following is NOT a piece of evidence Wegener used to support his hypothesis of continental drift and the existence of Pangea?

• The fit of the continents

• Fossil correlations across continents

• Similar rock formations on different continents

• The presence of ocean currents

What can fossils tell us about Earth’s past?

• Fossils can provide information about past climates and environments.

• Fossils can predict future weather patterns.

• Fossils can tell us about the future of technology.

• Fossils can provide information about modern animal behavior.

How has Earth’s climate and surface changed over time?

• Through natural processes and human activities

• Only through natural processes

• Only through human activities

• It has not changed
