Seafloor Spreading & Plate Tectonics Review

Front

What occurs at a divergent boundary?

Back

Plates pull apart.

Front

Where is the oldest rock typically found in relation to mid-ocean ridges?

Back

The oldest rock is found farthest from the ridge, often at location O.

Front

What type of plate boundary is most likely to form a mountain range?

Back

Convergent Boundary.

Front

Where do most volcanoes and earthquakes occur?

Back

Along tectonic plate boundaries.

Front

What landform can occur at a divergent plate boundary?

Back

Mid-ocean ridge.

Front

What is a convergent boundary?

Back

A tectonic plate boundary where plates move towards each other, often forming mountains or subduction zones.

Front

What is a transform boundary?

Back

A tectonic plate boundary where plates slide past each other horizontally.

Front

What geological feature is formed at a subduction zone?

Back

Ocean trenches and volcanic arcs.

Front

What is the process of seafloor spreading?

Back

The formation of new oceanic crust as magma rises to the surface at mid-ocean ridges.

Front

What is the significance of the mid-ocean ridge?

Back

It is a divergent boundary where new oceanic crust is created.
