Answer:
5th worlds largest population
Explanation:
All answers are correct except the option "avoiding soil compaction"
Soil compaction makes the soil cohesively bound and make them less available for erosion.
Crop rotation holds the soil by increasing soil productivity and increasing the plantation that holds the soil
Mulching is the strategy adopted at farmland where straw blend is spread-ed over the soil mass to avoid its erosion.
Wind breaks are used at farmland to avoid or reduce soil erosion
Increasing the vegetation mean increasing the plants which through their roots hold the soil and prevent it form being carried away.
The four spheres of the Earth includes the Geosphere, Hydrosphere, Biosphere and Atmosphere. The sphere that there is interaction in runoff from farming into the local areas is on Hydrosphere. Hydrosphere <span>is the liquid water component of the Earth. It includes the oceans, seas, lakes, ponds, rivers and streams.</span>
The convection drive plates tectonics through a combination of pushing and spreading apart at mid-ocean ridges and pulling and sinking downward at subduction zones. At subduction zones, two tectonic plates meet and one slides beneath the other back into the mantle, the layer underneath the crust.
