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.
In case of a two dimensional plane, two intersecting lines are said to be perpendicular lines if they intersect at right angles. In the figure, the lines $\overleftrightarrow{AB}$ and $\overleftrightarrow{CD}$ are perpendicular to each other intersecting at the point P. We can write.ase 3: Two lines are parallel and there is no intersection. Case 4: The two lines are not parallel, but there is no intersection. Such lines are called skew lines. If P(x, y, Z) is the intersecting point of the two line segments, it will be on both the line segments.
