Why are small leaves an adaptation in a desert environment?
a. they trap less water.
b. they minimize water loss.
c. they absorb more light.
d. they fall out in the winter.

The correct answer is b. They minimize water loss.

Desert plants such as Acacia, Opuntia are adapted to live in the arid environment. They are adapted in many ways, on such is they have either small leaves or leaves are modified into spines. These adaptation are to conserve water. Small leaves have very small surface area which help to reduce water vapor loss during transpiration. Besides, a small leaf doesn’t reach as high a temperature as a large leaf in the sunlight.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
