Introduction

Deserts are regions that receive very little precipitation, typically less than 250 millimeters (10 inches) of rain per year. They cover about one-third of the Earth’s land surface and are found on every continent.

 Unique Characteristics of Deserts:  

1. Extreme Temperatures:

   • Hot Deserts: These deserts, like the Sahara, can experience scorching daytime temperatures that soar above 50°C (122°F), while nighttime temperatures can plummet dramatically.

   • Cold Deserts: Deserts like Antarctica and the Gobi experience frigid temperatures, often dropping well below freezing.

2. Low Precipitation:

   • Deserts receive minimal rainfall, which can be sporadic and unpredictable. Some deserts may go years without significant rain.

3. Adapted Flora and Fauna:

   • Plants and animals in deserts have evolved unique adaptations to survive the harsh conditions. For example, cacti store water in their thick stems, and animals like the fennec fox have large ears to dissipate heat.

4. Unique Landscapes:

   • Deserts feature diverse landscapes, including sand dunes, rocky plateaus, and salt flats. These formations are shaped by wind and water erosion over time.
