'The Desert' — Practice

Question 1

How are desert plants adapted to survive in dry conditions?

Accepted Answer

Desert plants store water in thick stems (like the cactus), reduce water loss with small or spiny leaves and waxy coatings, and reach deep groundwater with long roots (like mesquite). Spines also protect them from thirsty animals. These adaptations let them survive long periods without rain.

Question 2

How are desert animals adapted to survive extreme temperatures?

Accepted Answer

Many desert animals are nocturnal (active at night) to avoid the daytime heat, and they burrow to stay cool. Camels store fat in their humps for energy and water, fennec foxes have large ears to release heat, and kangaroo rats produce concentrated urine to conserve water. These adaptations help them survive heat and scarcity of water.

Question 3

What are two common misconceptions about deserts?

Accepted Answer

That deserts are full of sand (only about 20% are sandy) and that they are lifeless (they actually support varied, well-adapted life). Also that they are always hot (some are cold).

Question 4

What defines a desert?

Accepted Answer

A desert is a region that receives less than 25 cm of rainfall per year.
