Description

"The Effect of Rivers on Land" Earth's Surface and Its Changes PPT Courseware 2

teaching objectives

Name and explain the formation of rivers and how they erode the land.

Name and explain how the erosion and sedimentation of rivers play a role in the formation of Earth's topography and landforms?

The role of rivers in land

The impact of rivers on land

Landforms formed by erosion and sedimentation

Explore the impact of rivers on land

Recall the findings from experiments on sedimentation of soil in water.

Please tell me whether the river will erode the land on both sides? A small river starts from the mountains. What can we see in its path, from its upper, middle and lower river beds? Why?

River flow experiment

—Analyze and explain flowing water, river channels, and where erosion occurs? Where does sedimentation occur? Please mark it in pencil in the book.

Our conclusion

Rivers are also formed by flowing water eroding land.

Erosion and sedimentation occur all the time in nature. Erosion causes soil loss in some raised places on the ground, and sedimentation and fills in some low-lying places. Erosion and sedimentation form different topography and landforms on the earth.

landforms formed by erosion and sedimentation

Besides flowing water, what other natural force can cause erosion and sedimentation of land?

Talk about the erosion and sedimentation effects of wind, glaciers, and waves on land.
