Surface runoff happens when, usually a liquid, flows from a high point to a low point because of a driving force in pressure difference as evident in the difference in elevation. In other words, liquid will runoff from the mountains to the plains. Since a low, flat plain has no difference in elevation, it will not cause the fluid to flow. Thus, it is impossible for surface runoff to happen within a low, flat plain.
The properties of parallelograms are contained below:
- They have opposite sides which are congruent to each other. BC = ED
- They have Opposite angles which are congruent also.
- Consecutive angles are known to sum up to 180 degrees. They are supplementary.
- If an angle is right, all other angles are right.
- The diagonals are said to bisect each other.
