a) Deserts are areas with high precipitation ^ Deserts are areas with low precipitation
b) Yes
c) No
d) Deserts occur in both tropics and sub-tropics ^ Deserts only occur in the tropics

Answer 1

A desert is an area with extremely low precipitation, not limited to subtropical regions, and is known for its hot days and cold nights, as exemplified by the Sahara and Namib deserts.

Step-by-step explanation:

A desert is an area with extremely low precipitation, often having less than 30 cm (12 in) annually. Deserts are characterized by low moisture levels, which results in very few plants and a stark landscape. They occur in various regions, including the subtropics, but are not restricted to these areas alone. Subtropical deserts, like the Sahara Desert in northern Africa and the Namib Desert in southwestern Africa, exist between 15° and 30° north and south latitude and are decidedly dry, with evaporation often exceeding precipitation. These deserts can experience extreme temperatures, rising above 60°C (140°F) during the day and approaching 0°C (32°F) at night.

Regarding the question options, the correct answers are:

1. Deserts are areas with low precipitation.
2. No, deserts do not occur only in the subtropics.
3. Deserts occur in both tropics and subtropics.
