Plate Tectonics and Continental Drift

Front

What is Plate Tectonics?

Back

The theory that explains the structure and movement of Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What is Continental Drift?

Back

The hypothesis that continents have moved over geological time and were once joined together in a single landmass called Pangaea.

Front

What are tectonic plates?

Back

Large, rigid pieces of the Earth's lithosphere that move and interact at their boundaries, causing geological activity.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where two plates collide, often resulting in mountain formation or subduction.

Front

What is a divergent boundary?

Back

A tectonic plate boundary where two plates move apart, leading to the formation of new crust, such as at mid-ocean ridges.

Front

What is a transform boundary?

Back

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

Front

What is subduction?

Back

The process by which one tectonic plate moves under another plate and sinks into the mantle.

Front

What landform is typically found at a divergent boundary?

Back

Mid-Ocean Ridge, where new oceanic crust is formed.

Front

What geological feature is associated with convergent boundaries?

Back

Mountain ranges, such as the Andes, formed by the collision of tectonic plates.

Front

What is the San Andreas Fault?

Back

A transform boundary in California where the Pacific Plate and the North American Plate slide past each other.
