Meera Rana answered |
Explanation: While it's true that rice is grown in the plains of the north, the reason isn't solely due to high rainfall. Rice cultivation requires a lot of water, but it also depends on temperature, soil type, and availability of labor. Moreover, rice is also grown in regions with less rainfall with the help of irrigation. Therefore, while rainfall is a factor, it's not the sole or primary reason for rice cultivation in the northern plains.

Anisha kapoor answered |
Explanation:
Airways is not a land means of transport. Here is the detailed explanation:
Land means of transport:
Land means of transport refer to the various modes of transportation that operate on land. These modes are used to transport people, goods, and materials from one place to another within the same country or region. The main land means of transport are:
1. Roadways: Roadways refer to the system of roads and highways that are used for transportation by vehicles like cars, buses, trucks, and motorcycles. Roadways are the most common and widely used means of land transport.
2. Railways: Railways are a mode of transport consisting of a network of tracks along which trains travel. Railways are used for both passenger and freight transport. Trains run on tracks and are powered by locomotives.
3. Pipelines: Pipelines are used to transport liquids or gases. They are long, cylindrical structures that transport materials through them. Pipelines are commonly used for transporting oil, gas, and water over long distances.
Airways:
Airways, on the other hand, are not a land means of transport. Airways refer to the system of transportation by aircraft. Airplanes and helicopters are used for transporting people and goods through the air. Unlike roadways, railways, and pipelines, airways do not operate on land but in the air.
Summary:
In summary, the correct answer is option 'B' - Airways. Airways are not a land means of transport as they operate in the air rather than on land. Roadways, railways, and pipelines are all examples of land means of transport.

Kiran Mehta answered |
soil conservation include crop rotation, cover crops, conservation tillage and planted windbreaks and affect both erosion and fertility. When plants, especially trees, die, they decay and become part of the soil.
Conservation Trees are an integral part of production agriculture as they improve crop yields and preserve topsoil for future abundant harvests. Planted along streams and wetlands, they prevent erosion and clean the water. Planting Conservation Trees in marginal areas of agricultural land attracts wildlife, sequesters carbon, and helps with flood control.

Industrial Effluents as the Main Cause of Land and Water Pollution in India
Introduction:
Land and water pollution are major environmental issues in India, affecting human health, animals, and plants. Various factors contribute to these problems, but the main cause in recent years is industrial effluents.
Industrial Effluents:
Industrial effluents are liquid, solid, or gaseous wastes generated by manufacturing and processing industries. These wastes contain harmful substances such as heavy metals, chemicals, and organic compounds that can pollute the land and water.
Sources of Industrial Effluents:
There are many industries in India that release their effluents into the environment, including textile, leather, chemical, pharmaceutical, and food processing industries. These industries generate huge amounts of waste that are often discharged into nearby rivers, lakes, and groundwater sources, leading to land and water pollution.
Effects of Industrial Effluents:
The discharge of industrial effluents into the environment has several negative impacts on the ecosystem, including:
1. Health Effects: The harmful substances in industrial effluents can cause various health problems, including skin diseases, respiratory issues, and cancer.
2. Environmental Effects: The land and water pollution caused by industrial effluents can harm the environment, including soil degradation, water contamination, and loss of biodiversity.
3. Economic Effects: The cost of treating polluted water and soil is high, and the pollution can also impact the tourism and fishing industries.
Conclusion:
In conclusion, industrial effluents are the main cause of land and water pollution in India in recent years. To address this issue, the government needs to enforce strict regulations on industries to prevent them from discharging harmful substances into the environment. The industries themselves must also adopt sustainable practices and invest in technologies that reduce waste and pollution.
Introduction:
Land and water pollution are major environmental issues in India, affecting human health, animals, and plants. Various factors contribute to these problems, but the main cause in recent years is industrial effluents.
Industrial Effluents:
Industrial effluents are liquid, solid, or gaseous wastes generated by manufacturing and processing industries. These wastes contain harmful substances such as heavy metals, chemicals, and organic compounds that can pollute the land and water.
Sources of Industrial Effluents:
There are many industries in India that release their effluents into the environment, including textile, leather, chemical, pharmaceutical, and food processing industries. These industries generate huge amounts of waste that are often discharged into nearby rivers, lakes, and groundwater sources, leading to land and water pollution.
Effects of Industrial Effluents:
The discharge of industrial effluents into the environment has several negative impacts on the ecosystem, including:
1. Health Effects: The harmful substances in industrial effluents can cause various health problems, including skin diseases, respiratory issues, and cancer.
2. Environmental Effects: The land and water pollution caused by industrial effluents can harm the environment, including soil degradation, water contamination, and loss of biodiversity.
3. Economic Effects: The cost of treating polluted water and soil is high, and the pollution can also impact the tourism and fishing industries.
Conclusion:
In conclusion, industrial effluents are the main cause of land and water pollution in India in recent years. To address this issue, the government needs to enforce strict regulations on industries to prevent them from discharging harmful substances into the environment. The industries themselves must also adopt sustainable practices and invest in technologies that reduce waste and pollution.

Meera Kapoor answered |
Resources are vital for human survival as well as for maintaining quality of life. It was believed that resources are free gifts of nature. As a result, human beings used them indiscriminately. This led to the following major problems:-
- Depletion of resources for the greed of few.
- Accumulation of resources in a few hands which in turn, divided the society into rich and poor.
- Indiscriminate use of resources causing various global ecological crises such as global warming, depletion of the ozone layer, environmental pollution & land degradation.

Neha Joshi answered |
Afforestation is the establishment of a forest or stand of trees in an area where there was no previous tree cover. Many government and non-governmental organizations directly engage in programs of afforestation to create forests, increase carbon capture.Afforestation is the process of planting trees, or sowing seeds, in a barren land devoid of any trees to create a forest. The term should not be confused with reforestation, which is the process of specifically planting native trees into a forest that has decreasing numbers of trees.As plant roots hold the soil, Afforestation prevents soil erosion and enables better retention of water.
