Formation of Landforms

Click on the flashcard to see the answer

What natural process can create mountains?

Mountains can be formed by tectonic plate collisions that push up the earth's surface.

How are valleys commonly formed?

Valleys can form from erosion by rivers over long periods.

What geological activity can lead to plateau formation?

Plateaus form from volcanic activity or tectonic forces that uplift the land.

How are canyons carved?

Canyons are carved primarily by river erosion over long timeframes.

How do glaciers contribute to landform creation?

Glaciers carve through landscapes, forming valleys and shaping mountains.

What causes the formation of deserts?

Deserts form due to low precipitation and evaporation exceeding rainfall.

How do volcanic islands form?

Volcanic islands form from eruptions that build up lava above sea level.

What contributes to the formation of deltas?

Deltas are formed from sediment deposition as rivers meet slower-moving water bodies.

What is the role of wind in dune formation?

Wind moves sand grains which accumulate, forming dunes.

How do erosion and sedimentation shape landforms?

Erosion wears down land while sedimentation builds up land, both shaping landscapes.

What is the process of fjord creation?

Fjords are carved by glacial activity as ice advances and retreats.

How are swamps created?

Swamps form in areas with poor drainage that accumulate water.

What is the main force behind the creation of hills?

Hills can form from erosion that removes surrounding earth or from tectonic activity.

What factors lead to island creation besides volcanic activity?

Islands can also form from rising sea levels covering land or through coral build-up.

How can human activities influence landforms?

Humans alter landforms through construction, mining, and deforestation.
