Geological Features

Question 1

What type of convergence leads to the formation of mountains?

Answer 1

Continental-continental convergence

This process occurs when two continental plates collide, leading to the uplift of mountain ranges.

Question 2

Which geological feature is formed by oceanic-oceanic convergence?

Answer 2

Island Arcs

Island arcs are typically formed from volcanic activity associated with subduction zones where one oceanic plate is forced under another.

Question 3

What geological structures are found at divergent boundaries under the ocean?

Answer 3

Mid-Ocean Ridges

These ridges are formed by the upwelling of magma that creates new oceanic crust as tectonic plates move apart.

Question 4

What are the features formed at continental divergent boundaries?

Answer 4

Rift Valleys

Rift valleys occur when tectonic plates pull apart, creating low-lying areas that can eventually lead to the formation of new ocean basins.

Question 5

What geological feature is associated with subduction zones?

Answer 5

Deep Trenches

Deep trenches are formed when one tectonic plate is forced down into the mantle beneath another plate, often associated with volcanic arcs.
