Plate Tectonics

What is plate tectonics?

• The study of landforms

• The movement of the Earth's crust

• The study of earthquakes and volcanoes

• The formation of mountain ranges

How many large plates is the Earth's crust broken into?

• Five

• Seven

• Ten

• Twelve

Which type of plate is denser and thinner?

• Oceanic plate

• Continental plate

• Both are equally dense

• Neither is dense

What usually happens when oceanic plates collide with continental plates?

• Oceanic plates sink under continental plates

• Continental plates sink under oceanic plates

• Both plates sink under each other

• Both plates resist subduction

What patterns can the locations of mountain ranges, deep ocean trenches, ocean floor structures, earthquakes, and volcanoes give us?

• Patterns of climate change

• Patterns of human settlement

• Patterns of plate tectonics

• Patterns of animal migration

Where do major mountain ranges often form?

• Inside continents

• In the middle of oceans

• On small islands

• On the edge of continents

What are the three types of tectonic plates?

• Convergent, divergent, and transform

• Oceanic, continental, and sliding

• Fault, cliff, and volcano

• Earthquake, mountain, and ocean

What occurs along convergent boundaries?

• Plate sliding

• Water or magma filling the space

• Formation of new land

• Earthquakes and volcanoes

What happens when plates move away from each other?

• Earthquakes occur

• Volcanoes form

• Water or magma fills the space

• Continents collide

What are transform boundaries also known as?

• Sliding boundaries

• Colliding boundaries

• Divergent boundaries

• Convergent boundaries
