THE SOIL

The action of the wind, water, rain and heat in the soil formation is called:

• humus

• weathering

• loss of vegetation

• ploughing

THE SOIL

This cause of erosion is for cutting down trees:

• deforestation

• rainfall

• overgrazing

• wind

THE SOIL

This cause is when the cattle reduces the vegetation of the soil:

• loss of vegetation

• rainfall

• overgrazing

• wind

SOIL CONSERVATION

This strategy prevents floods and washing away of rich fertile soil:

• cover crops

• terrace farming

• afforestation

• embankments

SOIL CONSERVATION

This strategy hills are cut in steps along slopes and reduces speed of water:

• cover crops

• terrace farming

• afforestation

• embankments
