किस कारण से अपक्षयित पदार्थ धीरे-धीरे रेगोलिथ बनाता है?

Why does weathered material gradually form regolith?

Explanation opens after your attempt
Correct Answer

C. क्योंकि टूटे और बदले खनिज मूल चट्टान पर ढीली परत बनाते हैंBecause broken and altered minerals form a loose layer over bedrock

Step 1

Concept

Regolith is the loose layer of weathered material above bedrock. For exams treat it as a base for soil formation.

Step 2

Why this answer is correct

The correct answer is C. क्योंकि टूटे और बदले खनिज मूल चट्टान पर ढीली परत बनाते हैं / Because broken and altered minerals form a loose layer over bedrock. Regolith is the loose layer of weathered material above bedrock. For exams treat it as a base for soil formation.

Step 3

Exam Tip

रेगोलिथ मूल चट्टान के ऊपर ढीले अपक्षयित पदार्थ की परत है। परीक्षा में इसे मिट्टी निर्माण का आधार मानें।

मिट्टी निर्माण के संदर्भ में अपक्षय का सबसे सही महत्व क्या है?

What is the most accurate importance of weathering for soil formation?

Explanation opens after your attempt
Correct Answer

C. यह मूल चट्टान को खनिज कणों और रेगोलिथ में बदलता हैIt converts bedrock into mineral particles and regolith

Step 1

Concept

Weathering prepares the mineral base of soil. For exams remember it as an initial stage of soil formation.

Step 2

Why this answer is correct

The correct answer is C. यह मूल चट्टान को खनिज कणों और रेगोलिथ में बदलता है / It converts bedrock into mineral particles and regolith. Weathering prepares the mineral base of soil. For exams remember it as an initial stage of soil formation.

Step 3

Exam Tip

अपक्षय मिट्टी के खनिज आधार को तैयार करता है। परीक्षा में मृदा निर्माण की प्रथम अवस्था के रूप में इसे याद रखें।

शुष्क क्षेत्र में यांत्रिक अपक्षय के बावजूद मोटी रासायनिक मृदा कम क्यों बनती है?

Why does thick chemically weathered soil form less in dry regions despite mechanical weathering?

Explanation opens after your attempt
Correct Answer

A. क्योंकि जल की कमी रासायनिक परिवर्तन सीमित करती हैBecause lack of water limits chemical alteration

Step 1

Concept

Water is essential for chemical weathering. In exams connect aridity with thinner soils.

Step 2

Why this answer is correct

The correct answer is A. क्योंकि जल की कमी रासायनिक परिवर्तन सीमित करती है / Because lack of water limits chemical alteration. Water is essential for chemical weathering. In exams connect aridity with thinner soils.

Step 3

Exam Tip

रासायनिक अपक्षय के लिए जल अत्यंत आवश्यक है। परीक्षा में शुष्कता को पतली मृदा से जोड़ें।

लैटराइट निर्माण में तीव्र रासायनिक अपक्षय की मुख्य भूमिका क्या होती है?

What is the main role of intense chemical weathering in laterite formation?

Explanation opens after your attempt
Correct Answer

A. सिलिका और क्षारों का लीचिंग द्वारा हटनाRemoval of silica and bases by leaching

Step 1

Concept

Heavy rainfall removes soluble materials by leaching and leaves iron aluminium residues. In exams link laterite with humid tropical weathering.

Step 2

Why this answer is correct

The correct answer is A. सिलिका और क्षारों का लीचिंग द्वारा हटना / Removal of silica and bases by leaching. Heavy rainfall removes soluble materials by leaching and leaves iron aluminium residues. In exams link laterite with humid tropical weathering.

Step 3

Exam Tip

अधिक वर्षा में लीचिंग से घुलनशील तत्व हटते हैं और लौह एल्युमिनियम अवशेष बचते हैं। परीक्षा में लैटराइट को उष्ण आर्द्र अपक्षय से जोड़ें।
