Anjali Kumar answered
Percentage of the world's surface used for agriculture

The correct answer is option D, 35%.

Explanation:

Definition of agriculture
Agriculture is the practice of cultivating plants and rearing animals for food, fiber, medicinal plants, and other products used to sustain and enhance human life.

Calculating the percentage
To determine the percentage of the world's surface used for agriculture, we need to consider the total land area dedicated to agricultural practices. According to the Food and Agriculture Organization (FAO) of the United Nations, as of 2020, the total land area used for agriculture globally is approximately 4.9 billion hectares.

Calculating the total surface area of the Earth
The total surface area of the Earth is approximately 510 million square kilometers, which is equivalent to 510 million hectares.

Calculating the percentage
Now, we can calculate the percentage of the world's surface used for agriculture:

Percentage = (Agricultural land area / Total land area) * 100
Percentage = (4.9 billion hectares / 510 million hectares) * 100
Percentage ≈ 35%

Therefore, approximately 35% of the world's surface is used for agriculture in some form.

Importance of agriculture
Agriculture plays a crucial role in sustaining human life and the global economy. It provides food security, employment opportunities, raw materials for various industries, and contributes to the overall development of a nation. Sustainable agricultural practices are essential to ensure the availability of food for a growing global population while preserving natural resources and minimizing environmental impact.

Conclusion
Understanding the percentage of the world's surface used for agriculture helps to highlight the significant impact of agriculture on our planet. With approximately 35% of the Earth's surface dedicated to agricultural practices, it is essential to promote sustainable farming methods and ensure the efficient use of land and resources to meet the growing demands for food and other agricultural products.

Agriculture can cause soil erosion.
  • a)
    True
  • b)
    False
Correct answer is option 'A'. Can you explain this answer?

Chetna Sharma answered
When farmers plow their fields they leave the soil bare and exposed to the elements. As a result, wind and rain can pretty easily sweep soil away into rivers and lakes.

At what rate does soil form naturally?
  • a)
    Moderately slowly
  • b)
    Moderately quickly
  • c)
    Very slowly
  • d)
    Very quickly
Correct answer is option 'C'. Can you explain this answer?

Swati Sharma answered
The correct option is C.
The time needed to form a soil depends on the latitude: in environments characterized by a mild climate, it takes 200-400 years to form 1 cm of soil. In wet tropical areas soil formation is faster, as it takes 200 years. In order to accumulate enough substances to make a soil fertile it takes 3000 years.

About when did agriculture begin?
  • a)

  • d)
    20,000 years ago
Correct answer is option 'B'. Can you explain this answer?

Sanchita Datta answered
Sometime around 10,000-12,000 years ago, our hunter-gatherer ancestors began trying their hand at farming.
First, they grew wild varieties of crops like peas, lentils and barley and herded wild animals like goats and wild oxen. Centuries later, they switched to farming full time, breeding both animals and plants, creating new varieties and breeds. Eventually, they migrated outward, spreading farming to parts of Europe and Asia.

In the questions given below there are two statements marked as Assertion (A) and Reason (R). Read the statements and choose the correct option:
Assertion (A) : A few economists think that Indian farmers have a bleak future if they continue growing foodgrains on the holdings that grow smaller and smaller as the population rises.
Reason (R) : Indian farmers should diversify their cropping pattern from cereals to high-value crops.
  • a)
    Both (A) and (R) are true and (R) is the correct explanation of (A).
  • b)
    Both (A) and (R) are true but (R) is not the correct explanation of (A).
  • c)
    (A) is correct but (R) is wrong.
  • d)
    (A) is wrong but (R) is correct.
Correct answer is option 'B'. Can you explain this answer?

Assertion (A): The statement is true because as the population increases, the size of landholdings per farmer continues to shrink, making it difficult for farmers to sustain themselves by growing only foodgrains. This is due to limited profitability and increasing costs.
Reason (R): This is also true because diversifying cropping patterns from cereals to high-value crops like fruits, vegetables, and cash crops can significantly improve farmers' incomes and make agriculture more sustainable.
Relationship between (A) and (R):  However, while R offers a potential solution, it does not directly explain why A is true. Thus, R is not the correct explanation for A.
