What makes the Gobi Desert of Asia a desert?
a. The growing season there is very short
b. It is hot
c. Temperatures vary little from summer to winter
d. It is dry

Verified step by step guidance

1. Understand the definition of a desert: A desert is typically defined by its low precipitation levels, not necessarily by temperature or other factors.
2. Analyze the options provided: Option (a) refers to the growing season, which is not a defining characteristic of a desert. Option (b) refers to heat, but not all deserts are hot (e.g., cold deserts like Antarctica). Option (c) refers to temperature variation, which is also not a defining factor of a desert. Option (d) refers to dryness, which aligns with the definition of a desert.
3. Recall that the Gobi Desert is classified as a cold desert, meaning it experiences significant temperature fluctuations and is not always hot, further ruling out options (b) and (c).
4. Focus on precipitation: The Gobi Desert receives very little rainfall annually, which is the primary reason it is classified as a desert.
5. Conclude that the correct answer is based on the defining characteristic of deserts, which is their dryness, making option (d) the most accurate choice.

Key Concepts

Desert Definition

A desert is defined as a region that receives very little precipitation, typically less than 250 mm (10 inches) annually. This lack of moisture leads to arid conditions, which are a hallmark of desert ecosystems. Understanding this definition is crucial for identifying the characteristics that classify an area as a desert.

Climate Factors

Climate factors such as temperature, humidity, and precipitation patterns play a significant role in determining the characteristics of a desert. In the case of the Gobi Desert, its dry climate, along with extreme temperature variations between summer and winter, contributes to its classification as a desert. Recognizing these climatic influences helps in understanding the environmental conditions of desert regions.

Growing Season

The growing season refers to the period during which conditions are suitable for plant growth, typically defined by temperature and moisture availability. In deserts like the Gobi, the growing season is often very short due to extreme temperatures and limited rainfall, which affects the types of vegetation that can thrive. This concept is important for understanding the ecological dynamics of desert environments.
