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.
A line segment is a part of a line having two endpoints. A ray is a part of a line with one endpoint and goes on and on in one direction... Parallel lines are lines that never intersect or cross one another. Perpendicular lines cross each other or intersect at right angles. An angle is two lines that meet at an endpoint called a vertex. An angle can be named by the three letters that form it or by the letter that is at its vertex. An acute angle is one that measures less than 90 degrees with a protractor - that is how much the angle is open or the lines diverge from the vertex.
