What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often resulting in the formation of mountains or volcanic activity.

What is the Continental Drift Theory?

Back

The Continental Drift Theory is the theory that states that continents have moved over geological time and were once joined together in a single landmass.

What causes the movement of tectonic plates?

Back

The movement of tectonic plates is caused by convection currents in the mantle.

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally, often causing earthquakes.

What is the significance of the Himalayas in plate tectonics?

Back

The Himalayas are an example of a continent-to-continent convergent boundary, formed by the collision of the Indian and Eurasian plates.

What evidence did Wegener use to support his theory of continental drift?

Back

Wegener used evidence such as fossil similarities across continents, glacial deposits in warm regions, and the fit of the continents.

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new oceanic crust.

Front

What are convection currents?

Back

Convection currents are the circular movements of molten rock in the mantle caused by heat from the Earth's core, driving plate tectonics.

What is the Moho discontinuity?

Back

The Moho discontinuity is the boundary between the Earth's crust and the underlying mantle.
