Erosion Flashcards
What is Erosion?
Is the geological process in which earthen materials get worn away or transported by the natural forces such as wind or water or moving ice.
What is the opposite of Erosion ?
Deposition
What are the main agents of Erosion?
The main agents are liquid water, ice,wind
What is the transported material in erosion called?
Sediment
What is erosion by water?
Erosion by water is when running water like streams or rivers wears away banks and creates larger valleys as the process repeats the valleys get larger and larger.
For example, the Fish River Canyon is the largest canyon in Afrika and is made by Erosion.
How does erosion create coastal landscapes?
The battering forces of ocean waves also erodes seaside cliffs. The action of erosion can take an array of coastal landscape features. Erosion can also make holes that later can form caves and when the water breaks through the back of the cave it can form an arch. Then the continuous waves can cause the arch to fall forming sea stacks and rock columns.
What is coastal erosion?
Coastal erosion by waves of the sea wears away of rocks, pebbles, earth, or sand on the beach this can change the shape of entire coastlines.
How does wind contribute to erosion
Wind is a powerful agent of erosion. Wind-driven processes constantly transport dust, sand, and ash from one place to another. Wind can sometimes blow sand to dunes.
How does moving ice contribute to erosion?
Ice, usually in the form of glaciers can erode the earth and create dramatic landforms.
What are ice ages?
The glacial periods are known as the ice age.
