Plate Tectonics Quiz

What is seafloor spreading?

• The gradual movement of the continents across the Earth's surface

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• An area where plates move away from each other, creating mid ocean ridges

• The region where two tectonic plates are in contact

What is continental drift?

• An area where plates move away from each other, creating mid ocean ridges

• The gradual movement of the continents across the Earth's surface

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• The region where two tectonic plates are in contact

Which of the following is an evidence for continental drift?

• Plant and animal fossils matching, rock layers being the same age and material, and the continents fitting together

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• The region where two tectonic plates are in contact

• An area where plates move away from each other, creating mid ocean ridges

What is plate tectonics?

• The gradual movement of the continents across the Earth's surface

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• A theory stating that the earth's surface is broken into plates that move

• An area where plates move away from each other, creating mid ocean ridges

What are tectonic plates?

• Sections of the Earth's crust that move due to convection currents in the mantle

• An area where plates move away from each other, creating mid ocean ridges

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• The gradual movement of the continents across the Earth's surface

What is a plate boundary?

• The gradual movement of the continents across the Earth's surface

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• An area where plates move away from each other, creating mid ocean ridges

• The region where two tectonic plates are in contact

What is a convergent plate boundary?

• An area where plates move away from each other, creating mid ocean ridges

• An area where plates move toward one another and collide

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• The gradual movement of the continents across the Earth's surface

What is a divergent plate boundary?

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• An area where plates move away from each other, creating mid ocean ridges

• The gradual movement of the continents across the Earth's surface

• The region where two tectonic plates are in contact

What is a transform plate boundary?

• The gradual movement of the continents across the Earth's surface

• The formation of new ocean crust as a result of magma pushing upward and outward from Earth's mantle to the surface

• An areas where two plates grind past each other resulting in faults lines

• An area where plates move toward one another and collide

What is oceanic crust?

• Thicker, less dense, older crust making the continents

• Thinner, more dense, younger crust formed by midocean ridges on the ocean floor

• Waves of energy caused by plate tectonics that travel through the Earth

• The region where an oceanic plate sinks down into the asthenosphere at a convergent boundary, usually between continental and oceanic plates
