The main factors that determine the amount of runoff in an area include the shape of the land, how people use the land, the type of soil, and the amount of rain and vegetation

Explanation:

Runoff is the way water that falls during raining do not stay static in the same place, it moves and affects the land where it lands, the way it moves is directly connected to gravitation rules, besides it is important to take into consideration how the use of land and the kind of vegetation can modify the runoffs, as they can make them move faster or slower at the same time that all elements together define how the land will be after each rainy season.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

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.
