What does runoff include
eduard

Answer:

Runoff is one of the ways land water finds its way back to the ocean, so it can join the water cycle again.

Usually, all the water that falls to the land gets soaked in the soil. However, during long rainy periods, or in the spring, when snow and ice glaciers start melting, soil gets oversaturated with water, so this excess water start flowing on the earth's surface. Gravity directs this water from higher to lower areas, where it will flow into some valley river. This river will take the runoff water to another river, then to the sea or the ocean.

Now this water can evaporate and start the water cycle once more.

The negative effects of tilling include _____. A increased soil erosion B reduced soil drainage C reduced need for energy input
Vikentia [17]

Answer:

A

Explanation:

Tilling agitates the topsoil and removes ‘unnecessary’ vegetation so the main crop can grow without competition. Tilling improves soil aeration and drainage for plants to grow well.  Nonetheless, it can lead to other consequences such as soil erosion because it loosens the soil and makes it easy to be carried away by wind and water.
