Answer 1

Answer: Multi-cell Line

Step-by-step explanation:

Multi-cell line storms form in a long, narrow line. While multi-cell lines may be just 10 to 20 miles wide, they can be hundreds of miles long. Multi-cell lines are known as "squall lines."

Answer 2

B. Multi-cell line

Step-by-step explanation:

A multi-cell line, or how it is more commonly known, a squall line, is basically a group of storms forming a line, like a bow, they have been seen to cover hundreds of miles long but usually only 10 or 20 miles wide.

It is theorized that this is because when a cyclone is formed, there are two forces of "wind" one ahead and one behind, concentrating air masses as if the winds were "squishing" them to form a line.
