With reference to the features of mountains, consider the following statements: 1. As you go higher in the mountains, the climate becomes colder. 2. The harsh climate attracts a very high population density. 3. Steep slopes provide the most suitable land for large-scale farming. Which of the statements given above is/are correct?

Correct Option The correct option is (a) 1 only. Explanation Mountains are landforms that rise prominently above their surroundings, exhibiting distinct climatic and topographical characteristics. These features significantly influence human settlement patterns and economic activities such as 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, the climate becomes colder as one moves higher up in the mountains. - Statement 2 is Incorrect: Mountains generally have harsh climates, rugged terrain, and limited infrastructure, making life difficult. These factors result in a sparse population rather than a high population density. Most of the world's population is concentrated in plains due to milder climates and ease of construction and transport. - Statement 3 is Incorrect: Steep slopes are prone to soil erosion and lack the flat terrain required for the operation of farm machinery. While terrace farming is practiced in some mountain regions, steep slopes are not the most suitable land for large-scale farming. Plains and river valleys provide the most fertile and suitable land for extensive agriculture. Key Takeaway: Mountainous regions are characterized by decreasing temperatures with altitude, rugged terrain, and harsh living conditions, which naturally limit population density and large-scale agricultural viability compared to plains.

Solution

Correct Option

The correct option is (a) 1 only.

Explanation

Mountains are landforms that rise prominently above their surroundings, exhibiting distinct climatic and topographical characteristics. These features significantly influence human settlement patterns and economic activities such as 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, the climate becomes colder as one moves higher up in the mountains.
Statement 2 is Incorrect: Mountains generally have harsh climates, rugged terrain, and limited infrastructure, making life difficult. These factors result in a sparse population rather than a high population density. Most of the world's population is concentrated in plains due to milder climates and ease of construction and transport.
Statement 3 is Incorrect: Steep slopes are prone to soil erosion and lack the flat terrain required for the operation of farm machinery. While terrace farming is practiced in some mountain regions, steep slopes are not the most suitable land for large-scale farming. Plains and river valleys provide the most fertile and suitable land for extensive agriculture.

Key Takeaway: Mountainous regions are characterized by decreasing temperatures with altitude, rugged terrain, and harsh living conditions, which naturally limit population density and large-scale agricultural viability compared to plains.
