Explanations: Arable land is specifically defined as the fraction of the Earth's surface that is suitable for farming and growing crops. This term is commonly used in agriculture and environmental studies to describe the land that can be used for agricultural purposes.

Option Analysis:

Option A: Productive land refers to land that is capable of producing goods or services, but it is not specifically defined as farmable land.
Option B: Ecumene refers to the inhabited portion of the Earth's surface, not specifically the land that is suitable for farming.
Option C: Arable land is the correct term for the portion of the Earth's surface that is suitable for growing crops.
Option D: Populated land refers to areas where people live, not specifically farmable land.
Option E: Carrying capacity capable is not a standard term used in agriculture or environmental studies.

Mnemonic: A for Arable, A for Agriculture.

5. Cultivated rows run sideways, rather than up and down. Slows down water erosion.

Correct Answer: Correct answer is: (D) Contour plowing.

Exam Relevance: AP Environmental Science, GATE, Civil Service Exams

Difficulty: Moderate

Concept notes: Contour plowing involves plowing across the slope of the land, following the contours of the land. This method helps to slow down water erosion by reducing the speed of water runoff.

Common Mistakes: A common misunderstanding is that contour plowing involves plowing up and down the slope, which would not effectively slow down water erosion.

Explanations: Contour plowing is a technique where rows are planted across the slope of the land, rather than up and down. This method helps to slow down water erosion by creating a series of small dams that reduce the speed of water runoff, thereby minimizing soil erosion.

Option Analysis:

Option A: Shelter belts are rows of trees or shrubs planted to protect crops from wind erosion, not water erosion.
Option B: Strip cropping involves alternating strips of different crops to reduce soil erosion, but it does not specifically address water erosion by altering the direction of rows.
Option C: Terracing involves creating flat areas on a slope to reduce water runoff, but it does not involve plowing rows across the slope.
Option D: Contour plowing involves plowing across the slope, which slows down water erosion by reducing the speed of water runoff.

Mnemonic: Contour plowing: "Contour" for "across the slope."

6. Which sector is most vulnerable to climate change in India?

Correct Answer: Correct answer is: (A) Agriculture.

Exam Relevance: UPSC, IAS, Civil Services, Competitive Exams
