Plate Tectonics 24

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, leading to the formation of new crust as magma rises to the surface.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates collide, and one plate may be forced below the other, often resulting in mountain formation or volcanic activity.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle, often leading to volcanic activity.

Front

What geological features are commonly associated with divergent boundaries?

Back

Divergent boundaries are commonly associated with mid-ocean ridges and rift valleys.

Front

What geological features are commonly associated with convergent boundaries?

Back

Convergent boundaries are commonly associated with mountain ranges, deep ocean trenches, and volcanic arcs.

Front

What geological features are commonly associated with transform boundaries?

Back

Transform boundaries are commonly associated with fault lines and earthquakes.

Front

How do fossil records support the theory of continental drift?

Back

Fossil records show that the same species of organisms existed on continents that are now separated by oceans, indicating they were once connected.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic plate movements.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away from the ridge.
