Which of these is an example of erosion? A light shining onto a mountain B wind blowing away sediment C rain breaking down rock D all of the above

B wind blowing away sediment

Explanation:

Erosion is the process whereby soil, nutrients, particles are transported away from one place to another via agents like water and wind. Generally, erosion exercises its effect on the surface of the soil.

Since erosion can occur as a result of action of water or wind on the surface of the Earth, "wind blowing away sediment" is an example of erosion among the other options listed in the question.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
