Continental drift and plate tectonics

What is the theory that explains how Earth's continents have moved over time?

Continental drift

Plate tectonics

Seafloor spreading

Volcanic activity

Which of the following are evidence for continental drift?

What is the name of the supercontinent that existed around 300 million years ago?

How do tectonic plates move?

They float on a layer of molten lava

They are pushed by ocean currents

They are pulled by gravity

They are driven by convection currents in the mantle

What happens at a convergent plate boundary?

Plates move apart

Plates slide past each other

Plates collide and one is forced beneath the other

Plates rotate around each other

Which tectonic plate is responsible for the formation of the Himalayas?

African Plate

Eurasian Plate

Pacific Plate

Australian Plate

What is the name of the boundary where two plates slide past each other horizontally?

Convergent boundary

Divergent boundary

Transform boundary

Subduction boundary

What is seafloor spreading?

The process of continents drifting apart

The formation of new oceanic crust at mid-ocean ridges

The sinking of one tectonic plate beneath another

The collision of two tectonic plates

What is a hotspot in the context of plate tectonics?

A location where two tectonic plates collide

A region of intense volcanic activity

A point on Earth's surface above a rising plume of hot mantle material

A zone of earthquake activity
