"Erosion of Land by Rainwater" Earth's Surface and Its Changes PPT Courseware

What is the difference between "runoff" and "rainwater" in a water collector? This shows what?

"Runoff" is turbid, while "rainwater" is clear.

This shows that running water has an erosive effect on the soil.

What we found:

Silt and clay from the land surface are washed away by water.

A ditch forms on the surface of the land

Rainwater is relatively clean, while runoff is turbid.

What are the factors that affect erosion?

The size of the land slope, the presence or absence of plant cover, and the amount of rainfall will affect the degree of soil erosion.

Let’s talk about our speculations and reasons.

Our research plans

Research topic: Effects of plant cover on land on erosion.

Our guess: If there is plant coverage, the land will be eroded to a small extent; if there is no plant cover, the land will be eroded to a large extent.

The same conditions: the slope on both sides is the same, the height of the water spray is the same, and the amount of precipitation must be the same.

Different conditions: one piece of soil with plant cover and one piece of soil without plant cover.
