Question

based on the selection, which two of the following statements are correct about flash floods?
a they can happen when ocean waves cannot reach the coast.
b they are created when heavy rains fall over a short period of time.
c they can occur when a dam suddenly bursts open.
d they can happen when earthquakes occur deep under the ocean.
e they are created when a period of light rain lasts for many days or weeks.

Explanation:

Flash floods are rapid - onset floods. Heavy rain in a short time can cause them, as well as a sudden dam burst. Ocean waves not reaching the coast and long - term light rain are not typical causes, and deep - ocean earthquakes usually lead to tsunamis rather than flash floods.

Answer:

B. They are created when heavy rains fall over a short period of time.
C. They can occur when a dam suddenly bursts open.
