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.
Perpendicular Lines. Quatr.us Math Geometry Lines. Perpendicular lines. Two lines are perpendicular if they cross at right angles. You can test this by extending the lines until they cross (if they do not cross then they are parallel).erpendicular Lines. Quatr.us Math Geometry Lines. Perpendicular lines.
