With reference to the climate in mountains, consider the following statements: 1. The climate becomes colder as one goes higher. 2. The harsh climate attracts dense population settlements. 3. Steep slopes result in less land available for farming. Which of the statements given above is/are correct?

Correct Option The correct option is (c) 1 and 3 only. Explanation Mountainous regions are characterized by significant variations in altitude and slope, which directly influence local climate, vegetation, and human activities. The relationship between elevation and temperature, along with the ruggedness of the terrain, determines the suitability of these areas for settlement and agriculture. Statement-wise Analysis - Statement 1 is Correct: In the troposphere, temperature decreases with an increase in altitude. This phenomenon is known as the Normal Lapse Rate, where the temperature drops by approximately 6.5°C for every 1,000 meters of ascent. Consequently, mountain climates become progressively colder at higher elevations compared to the plains at the base. - Statement 2 is Incorrect: Mountainous areas generally experience harsh climatic conditions, including extreme cold, high winds, and lower oxygen levels at high altitudes. Combined with rugged terrain and limited infrastructure, these factors make life difficult. Therefore, mountains typically support sparse populations rather than dense settlements. - Statement 3 is Correct: The topography of mountains includes steep slopes, which are prone to soil erosion and lack the flat terrain necessary for extensive agriculture. This scarcity of arable land limits farming activities, often necessitating specialized techniques such as terrace farming to utilize the available slopes. Key Takeaway: Altitude is inversely proportional to temperature in the troposphere (Normal Lapse Rate). The rugged terrain and harsh climate of mountain regions act as natural constraints on population density and agricultural scalability.

Solution

Correct Option

The correct option is (c) 1 and 3 only.

Explanation

Mountainous regions are characterized by significant variations in altitude and slope, which directly influence local climate, vegetation, and human activities. The relationship between elevation and temperature, along with the ruggedness of the terrain, determines the suitability of these areas for settlement and agriculture.

Statement-wise Analysis

Statement 1 is Correct: In the troposphere, temperature decreases with an increase in altitude. This phenomenon is known as the Normal Lapse Rate, where the temperature drops by approximately 6.5°C for every 1,000 meters of ascent. Consequently, mountain climates become progressively colder at higher elevations compared to the plains at the base.
Statement 2 is Incorrect: Mountainous areas generally experience harsh climatic conditions, including extreme cold, high winds, and lower oxygen levels at high altitudes. Combined with rugged terrain and limited infrastructure, these factors make life difficult. Therefore, mountains typically support sparse populations rather than dense settlements.
Statement 3 is Correct: The topography of mountains includes steep slopes, which are prone to soil erosion and lack the flat terrain necessary for extensive agriculture. This scarcity of arable land limits farming activities, often necessitating specialized techniques such as terrace farming to utilize the available slopes.

Key Takeaway: Altitude is inversely proportional to temperature in the troposphere (Normal Lapse Rate). The rugged terrain and harsh climate of mountain regions act as natural constraints on population density and agricultural scalability.
