Plate Tectonics and Earth's Structure

What is the theory that explains how the Earth's lithosphere is divided into several large and small plates that move and interact with each other?

• Continental Drift

• Pangaea

• Plate Tectonics

• Seafloor Spreading

Who proposed the theory of continental drift?

• Alfred Wegener

• Isaac Newton

• Marie Curie

• Charles Darwin

What is the name of the supercontinent that existed about 300 million years ago, which later broke apart to form the current continents?

• Atlantis

• Laurasia

• Gondwana

• Pangaea

What are the three types of plate boundaries?

• Divergent boundaries, convergent boundaries, and transform boundaries

• Subduction boundaries, collision boundaries, and sliding boundaries

• Tectonic boundaries, fault boundaries, and rift boundaries

• Oceanic boundaries, continental boundaries, and island boundaries

Which type of plate boundary occurs when two plates move away from each other?

• Transform plate boundary

• Convergent plate boundary

• Subduction plate boundary

Which type of plate boundary occurs when two plates collide and one is forced beneath the other?

• Subduction plate boundary

• Convergent plate boundary

• Transform plate boundary

• Divergent plate boundary

Which type of plate boundary occurs when two plates slide past each other horizontally?

• convergent plate boundary

• divergent plate boundary

What is the term for the shaking or trembling of the Earth's surface caused by the sudden release of energy in the Earth's crust?

• ground shaking

• tremor

• seismic activity

• earthquake

Which best describes the relationship between depth into the earth and temperature/density/pressure?

• As depth into the earth increases temperature, density, and pressure decrease.

• As depth into the earth increases temperature, density, and pressure increase.

• As depth into the earth decreases temperature, density, and pressure increase.

• As depth into the earth increases temperature and density increases but pressure decreases.

Which layers of the earth make up the lithosphere?

• Upper mantle and crust

• continental and oceanic crust

• Mantle, crust, outer core

• Inner core and outer core
