How can erosion and deposits form a plain?

What do you think?

Yes, that's right.

hmm, maby, say there was a hill and rain hit on it hard for a long period of time and it caused it to be flat? I'm not sure just guessing

Thanks!

You're welcome.

Erosion and deposition together can gradually shape a plain over time. Let's break down the process step by step.

1. Erosion: This refers to the wearing away of the Earth's surface by various agents such as water, wind, ice, or gravity. These agents can transport and remove the loose rock material from one place to another.

2. Weathering: Prior to erosion, weathering occurs when rocks and minerals are broken down into smaller pieces through physical or chemical processes. This prepares the material for transportation by erosive agents.

3. Transportation: Once rocks and sediments have been weathered, they can be transported by moving water (rivers, streams), wind, or ice. The energy of these natural forces moves the materials from higher elevations to lower areas.

4. Deposition: As the erosive agents (water, wind, ice) lose energy, they drop or deposit the sediments they were carrying. Typically, deposition occurs in areas where the agents slow down, such as in a river delta, floodplain, or at the mouth of a river. These deposited sediments settle over time.

5. Plain Formation: Over millions of years, the process of erosion and deposition repeats, continuously building up layers of sediment. These layers gradually spread out to form a relatively flat and low-lying landform known as a plain. However, it's important to note that the formation of a plain can also be influenced by tectonic activity or the presence of glaciers.

In summary, erosion removes and transports sediments, while deposition drops and accumulates them in low-lying areas, ultimately resulting in the gradual formation of a plain over an extensive period of time.
