plate boundaries

Front

What is a divergent boundary?

Back

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

Front

What is a convergent boundary?

Back

A convergent boundary is a type of plate boundary where two tectonic plates move towards each other, often leading to subduction or mountain formation.

Front

What is a transform boundary?

Back

A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally, commonly associated with earthquakes.

Front

What geological feature is commonly found at divergent boundaries?

Back

Mid-ocean ridges are commonly found at divergent boundaries, where new oceanic crust is formed.

Front

What geological feature is commonly associated with convergent boundaries?

Back

Mountains, deep ocean trenches, and volcanic arcs are commonly associated with convergent boundaries.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate slides under another, often leading to volcanic activity and the formation of deep ocean trenches.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is created at mid-ocean ridges as tectonic plates diverge.

Front

What are earthquakes?

Back

Earthquakes are sudden releases of energy in the Earth's crust that create seismic waves, often occurring at transform boundaries.

Front

What is continental drift?

Back

Continental drift is the theory that continents move over geological time, which was proposed by Alfred Wegener.

Front

What is a tectonic plate?

Back

A tectonic plate is a large, rigid piece of the Earth's lithosphere that moves and interacts with other plates.
