Erosion occurs based on the movement of water, wind, or ice over a surface and typically moves on the downward-creep slope because of Gravity.

Explanation:

Erosions have several stages, depending on the level of depth and the severity of their occurrence. Generally, they begin with the process of surface washing of the soils, also called leaching or laminar erosion; then, they intensify with the process of action of the rains and the winds, appearing some holes and marked "lines" on the earth, the erosions in furrows or erosive furrows.

Severe erosion occurs in mountainous areas with steep declivity. In some cases, when the relief is very steep, earth mass movement may occur, a phenomenon that can be intensified by the saturation of the soils by rainwater.

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
