Answers
Answer:
1.Soil conservation is important because it saves the soil through harsh weather and stops erosion. While soil is conservating it's getting more nutrients. The more we conserve soil the more crops grow, then we can sell the crops and get money. So to conserve the soil use biochar fertilizer.
2.From source to mouth. Rivers run from the mountains to the sea. They are fast and narrow at their source (start) and get steadily wider and slower toward the mouth. Flowing through steep mountains, a river is powerful enough to wear away the land underneath, creating V-shaped valleys and steep-sided gorges.
3.As the river enters the plain it twists and turns forming large bends known as meanders. Erosion causes material to get carried away or transported by water, breeze, etc. and eventually deposited. This process of erosion and deposition results into formation of new land-forms.
