What is EROSION?? What is SOIL erosion??

There are two different ways soil can be eroded By Water ‘gully erosion’ and ‘sheet erosion’ By Wind

Use the text book page 180 to write a definition of these words: 1.Soil erosion 2.Sheet erosion 3.Gully erosion 4.Wind erosion

Go Outside!! Although Grand Bahama does not see much wind erosion, you can identify ‘sheet’ and ‘gully’ erosion by water on our campus… Identify two areas on our campus… Draw a sketch of each with labels

Finish in Class or for Homework 1.List 5 human causes of soil erosion using your textbook in your own words (pg )
