Answers. Best Answer: A delta is formed when a high flow water body meets a low flow one. Meaning, when a river meets a lake or ocean. The river carries sediment because of it's high energy (flow). When it suddenly slows down the sediment drops out all at once and a delta forms.est Answer: A delta is formed when a high flow water body meets a low flow one.

Two lines are said to be intersecting lines if they have a common point. It is to be noted that if two straight lines intersect each other, they can intersect at exactly point and that point is said to be the intersecting point of those two lines. In the figure, there are two lines $\overleftrightarrow{AB}$ and $\overleftrightarrow{CD}$ are two straight lines and P is a common point.
Given two parallel lines and a transversal, alternate interior angles are congruent. The key here is that you are told the two lines are parallel, and you have learned that the relationships between the angles created by the intersection of the transversal line and the two parallel lines. All of the above are true based on the two lines being parallel with a transversal line intersecting.
