When the surface soil is washed away through excessive rains and floods, it is called A. Biodiversity B. Land degradation C. Deforestation D. Soil erosion

The correct answer is - option D. Soil erosion.

Explanation:

Soil erosion is a normally happening process that has an impact on all landforms. In common agriculture soil erosion alludes to the removing or disintegration of a field's top layer by the normal physical powers of water  

Running water is the main source of soil erosion since water is plenty of quantity and has great power. Exercises that eliminate vegetation upset the ground, or permit the ground to dry are exercises that expand disintegration.

Thus, the correct answer is - option D. Soil erosion.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
