jolli1 [7]

Answer:

Refer to explanation

Explanation:

Weather is the main cause behind most short term environmental changes

For example, a period of heavy rain may lead to a pond overflowing, and flooding the nearby shrubbery

Animals in the area would adapt to this by trying to keep away from the flooded area until it dries out, once the rain ends
