The correct answer is - faster.
The rates of erosion in the present are faster than what they have been throughout most of the geologic past. The reason for this increase in the speed of the erosion has primarily been attributed to the human activity. The humans tend to destroy lot of vegetation, be it forests, shrub-lands, or grasslands in order to clear up space for their activities and needs. This leads to much higher exposure of the soil to the process of erosion. The reason for that is that the soil is losing its natural protector form the erosion, the plants and their roots, which are holding the soil tightly and also provide cover for it. Once this natural protection is gone, the soil becomes loos, nothing is holding it, so the natural elements are eroding it very easy and quick.

Answer:
Because the gravity of the Earth is pulling on air molecules and pressing it against the ground, our atmosphere is thinner and thinner the higher up you go.
Explanation:
Earth is a planet that has an active core, thus it has a reasonably strong gravitational pull. Gravity manages to keep all things on the surface of our planet and the ones that are in the atmosphere to pull them down or keep them near. This affects the atmosphere as well.
The atmosphere is composed of gases, all of which are made out of atoms and molecules. They are very light, so Earth is pulling them towards it. This has resulted in a situation where the majority of the gases are close to the surface, in the lowest parts of the atmosphere, and as we go up there is less and less of them, so the atmosphere is thinner and thinner as the elevation increases.
Answer:
A. The angle of repose is the steepest angle at which unconsolidated sediments can sit without slipping downhill
Explanation:
The angle of repose is the steepest angle at which unconsolidated sediment can be piled without sliding downward. The angle is also known as critical angle . At this angle the unconsolidated sediments are at the verge of slumping . The angle between the surface of the piled sediments and the horizontal surface is the angle of the repose. At this angle the unconsolidated sediments have reached it limit of accommodating more materials unless it will slump downward.
The make up of the unconsolidated sediments can affect the angle of repose as rounded and fined gained rocks cannot be piled as rough texture d rock materials. The angle of repose can also be affected by the amount of solvents in the sediment. Various rocks sediments possess different angle of repose. Same sediment material can possess different angle of repose if the water contents varies .Example, the angle of repose for sand varies depending on the water contents. The true statement is option A.
The picture above illustrate the angle of repose.
Answer: not as serious as
Explanation:
The complete sentence will be:
"Ethnic and religious tensions in Central Asia are not as serious as those in the Caucasus.
The main reason which can be attributed to this lesser tensions are due to fact that the role of the Society Union helped in subduing the religion.
Therefore, the correct option is A
