Understanding Plate Tectonics

What is plate?

• A broken piece of Earth’s crust that floats on top of a mantle

• A solid piece of Earth's core

• A layer of liquid magma

• A type of rock formation

Why do plates move?

• Because they are floating on the top of the liquid mantle

• Due to gravitational pull

• Because of human activities

• Due to the Earth's rotation

What are plate boundaries?

• The boundaries where the plates move

• The edges of the Earth's core

• The lines of latitude

• The borders of continents

What is a destructive plate boundary?

• A plate margin where two plates move towards each other

• A plate margin where two plates move away from each other

• A plate margin where plates slide past each other

• A plate margin that does not exist

What happens when a continental plate and oceanic plate collide?

• The oceanic plate sinks under the continental plate

• Both plates float on the mantle

• They create a new mountain range

• They break apart

What is a constructive plate boundary?

• A boundary where two plates move away from one another

• A boundary where two plates collide

• A boundary where plates slide past each other

• A boundary that does not exist

What is sea-floor spreading?

• The process where new sea floor is formed at divergent boundaries

• The sinking of oceanic plates

• The collision of continental plates

• The movement of tectonic plates

What is a conservative plate boundary?

• A boundary where plate material is neither created nor destroyed

• A boundary where two plates move towards each other

• A boundary where two plates move away from each other

• A boundary that does not exist

What occurs when plates slide past each other?

• It creates a transform fault and can cause earthquakes

• It creates new land

• It causes volcanic eruptions

• It has no effect
