The Thar Desert experiences a significant temperature variation due to:

Explanation / व्याख्या:

The Thar Desert in northwestern India is known for its extreme temperature variations—very hot during the day and very cold at night. This is primarily due to:

• Dry conditions: Lack of moisture in the soil and air reduces the ability to retain heat.

• Sparse vegetation: Minimal plant cover means there is little insulation, so the ground heats up quickly during the day and cools rapidly at night.

Other factors like altitude and proximity to the sea have a minor effect; rainfall is very low in this desert.

थार मरूस्थल (उत्तर-पश्चिम भारत) अपने अत्यधिक तापमान भिन्नता के लिए जाना जाता है—दिन में अत्यंत गर्म और रात में बहुत ठंडा। इसका मुख्य कारण हैं:

• शुष्क परिस्थितियाँ: मिट्टी और वायुमंडल में नमी की कमी के कारण गर्मी को रोकने की क्षमता कम होती है।

• दुर्लभ वनस्पति: पौधों की न्यूनतम परत होने के कारण जमीन जल्दी दिन में गर्म और रात में जल्दी ठंडी हो जाती है।

अन्य कारण जैसे ऊँचाई और समुद्र से निकटता का प्रभाव कम है; मरूस्थल में वर्षा भी बहुत कम होती है।

🌟 Extra Facts / अतिरिक्त तथ्य:

1️⃣ Temperature Range

• Summer daytime: 45°C or more

• Winter nighttime: near freezing (0–5°C)

• Difference of 40–45°C between day and night is common.

2️⃣ Reasons for Dryness

• Located in rain shadow region of the Aravalli Hills

• Receives less than 250 mm of rainfall annually

3️⃣ Vegetation in Thar

• Mostly xerophytic plants (adapted to dry conditions)

• Examples: Khejri, Cactus, Ber (Indian Jujube)

4️⃣ Memorization Tip 🧠

• Thar = Hot Days + Cold Nights = Dry + Sparse Vegetation

❌ Why Other Options Are Incorrect:

• High altitude → Thar is mostly low-lying plains (~200–300 m)

• Proximity to the sea → Desert is far from the sea

• Frequent rainfall → Thar is arid, very little rain
