Description

"Reducing Land Erosion" Earth's Surface and Its Changes PPT Courseware

Flowing water, wind, glaciers, waves and gravity all erode the land, as does rain. Erosion causes soil loss in certain places and changes the topography. It also has a great impact on human production and life. To protect their homes, people look for ways to reduce erosion as much as possible.

What kind of disasters will the various forces of the earth, including humans themselves, cause to us when they change the topography of the earth's surface?

Landslides, debris flows, crustal changes, terrain changes, soil erosion

Design and build our homes

What kind of terrain do we build, and with what materials? Where to choose to build a house?

If a heavy rain is coming, can our homes withstand the storm without being damaged?

Predict what will happen to our homes after the heavy rain?

Experiment: What impact does heavy rain have on our homes?

Each group filled a sprinkler with water to simulate a heavy rain and observed whether their homes could withstand the attack of heavy rain.

Thinking: In a competition experiment, what conditions should remain the same for each group and why?

What should we observe during the experiment:

Has our home withstood the torrential rain? Where did the water go? Are our homes and terrain affected? Find evidence from experimental results.

Use a water collector to catch the outflowing water and observe: Is the runoff turbid? What does this mean?

Compare the experimental results with our predictions. Are the results the same as the predictions? What didn't we think of?

What do our experimental results indicate?
