Soil erosion removes the top soil that is the most valuable part of the soil for agricultural purposes. With this loss of important soil, there is lower yield but higher cost of cultivation.
Soil erosion will work its way downstream that will find its way into the water systems of cities. The top soil may contain pesticides and fertilizers. The soil will also find its way into streams and rivers where it could possibly clog up the natural channels of waterflow.
The cold water observed along the northern California coast in summer is mainly due to: upwelling .
- here Upwelling is a process in which deep, cold water rises toward the surface replaces warm water from the surface.
- Winds blowing across the ocean surface push water away. Water then rises up from beneath the surface to replace the water that was pushed away. This process is known as “upwelling.”
- Upwelling occurs in the open ocean and along coastlines. The reverse process, called “downwelling,” also occurs when wind causes surface water to build up along a coastline and the surface water eventually sinks toward the bottom.
- Water that rises to the surface as a result of upwelling is typically colder and is rich in nutrients. These nutrients “fertilize” surface waters, meaning that these surface waters often have high biological productivity. Therefore, good fishing grounds typically are found where upwelling is common.

Answer:
Total money: $58
percentage of total amount spent on lunches: 30%
30/100 = 0.3
To find money spent each week on lunch, multiply by percentages:
58*.30= 17.4
Total money spent on lunch is $17.40

Answer:
Earth's rotation around its axis results in the alternation of day and night. Earth also moves around the Sun on the ecliptic plane in an elliptical orbit.
Explanation:
This movement along with the fact that its axis is tilted to the ecliptic plane is causing the changing of seasons.
