Class 11 salinity MCQ Questions

Question 1/12 Hard Geography Geomorphic Processes Soil formation processes Class 11 Level 51

यदि वर्षा अधिक हो और वाष्पीकरण कम हो तो लवणता घटने की संभावना क्यों रहती है?

Why is salinity likely to decrease when rainfall is high and evaporation is low?

Explanation opens after your attempt

Correct Answer

C. क्योंकि जल घुलनशील लवणों को नीचे धो सकता हैBecause water can wash soluble salts downward

Step 1

Concept

More water can move salts below the root zone. Exam tip: understand inverse relation of salinity and leaching.

Step 2

Why this answer is correct

The correct answer is C. क्योंकि जल घुलनशील लवणों को नीचे धो सकता है / Because water can wash soluble salts downward. More water can move salts below the root zone. Exam tip: understand inverse relation of salinity and leaching.

Step 3

Exam Tip

अधिक जल लवणों को जड़ क्षेत्र से नीचे ले जा सकता है। परीक्षा में लवणता और लीचिंग का उल्टा संबंध समझें।

शुष्क क्षेत्रों में मृदा में लवण जमा होने का मुख्य कारण क्या है?

What is the main reason for salt accumulation in soils of arid regions?

Explanation opens after your attempt

Correct Answer

A. वाष्पीकरण अधिक और निक्षालन कम होनाHigh evaporation and low leaching

Step 1

Concept

Low rainfall does not wash salts downward and evaporation may bring them upward. Exam tip: link aridity with salinity.

Step 2

Why this answer is correct

The correct answer is A. वाष्पीकरण अधिक और निक्षालन कम होना / High evaporation and low leaching. Low rainfall does not wash salts downward and evaporation may bring them upward. Exam tip: link aridity with salinity.

Topic: Soil formation processes
Difficulty: Easy
Level: 51

Question Hindi:
शुष्क क्षेत्रों में मिट्टी में लवण जमा होने का कारण क्या हो सकता है?

Question English:
What can cause salt accumulation in soil in dry regions?

Options:
A. अधिक वाष्पीकरण और कम धुलाई / High evaporation and low leaching
B. बहुत अधिक हिमपात / Very heavy snowfall
C. पूर्ण छाया / Complete shade
