Tectonic Plate Movement

What does the lithosphere consist of?

• The upper mantle only

• The layer of the Earth below the lithosphere

• The Earth's crust and the solid outer part of the mantle

• The Earth's core

What are the two types of tectonic plates?

• Continental and Oceanic

• Asthenosphere and Lithosphere

• Upper and Lower

• Mantle and Core

What is the main difference between continental and oceanic plates?

• Oceanic plates are above the continental plates

• Continental plates are thinner but denser

• Oceanic plates are made up of granite

• Continental plates are thicker but less dense

Where are the majority of the world's active volcanoes located?

• Along transform boundaries

• Where two plates meet

• Inside the Earth's core

• In the asthenosphere

What is the Pacific Ring of Fire known for?

• Being the only location with divergent boundaries

• Having approximately 90% of the world's earthquakes

• Being a large area of calm seismic activity

• Having the most oceanic trenches

What happens at transform boundaries?

• Plates grind horizontally past each other

• Plates push toward each other

• Plates pull apart from each other

• Plates melt into each other

What landform is created by divergent oceanic plates?

• Rift valleys

• Volcanic arcs

• Mid-ocean ridges

• Mountain ranges

What is created at divergent boundaries?

• Island arcs

• Earthquakes

• Deep trenches

• New crust

What occurs when an oceanic plate and a continental plate converge?

• A rift valley is formed

• The continental plate is subducted under the oceanic plate

• The oceanic plate is subducted under the continental plate, creating mountains

• Both plates melt completely

What is a 'continental collusion'?

• When two oceanic plates converge

• When two continental plates converge and form large mountain ranges

• A type of transform boundary

• The process of creating new sea floor
