B. Short answer questions:

1. What are the five sources of energy available to us? Give two examples of each source?

Ans: The five sources of energy available to us are:

1. Solar Energy:

Examples: Solar panels converting sunlight into electricity, solar water heaters using sunlight to heat water.

2. Wind Energy:

Examples: Wind turbines generating electricity from wind power, windmills pumping water or grinding grain.

3. Hydropower:

Examples: Hydroelectric dams generating electricity from flowing water, waterwheels historically used to mill grains.

4. Biomass Energy:

Example: Burning wood for heating or cooking, biofuels derived from organic materials like ethanol from corn or biodiesel from vegetable oils.

5. Geothermal Energy:

Examples: Geothermal power plants using heat from beneath the Earth’s surface to generate electricity, geothermal heating systems for buildings.

2. What are the sources of pollution?

Ans: Regarding the sources of pollution, they include:

(i) Air Pollution: Caused by emissions from vehicles, industrial processes, and burning of fossil fuels like coal and oil.

(ii) Water Pollution: Resulting from industrial waste, agricultural runoff, sewage discharge, and oil spills.

(iii) Soil Pollution: Caused by chemicals from agricultural practices, mining activities, and improper disposal of waste.

(iv) Noise Pollution: Generated by urban areas, transportation, industrial machinery, and construction activities.

(v) Light Pollution: Arising from excessive artificial lighting in urban areas, disrupting ecosystems and affecting human health.

(d) Petroleum.

Ans: (b) Solar Energy.

B. Short Answer Questions:

1. Write any three actions which you can take to conserve energy.

Ans: Three ways to conserve energy are as follows:

(i) Switch off lights, fans, TV and other electrical items, when not in use.

(ii) Use tube lights and energy efficient bulbs that save energy rather than bulbs.

(iii) Electric items like air conditioners geysers, heaters and dryers use a lot of electrical power. Use them when necessary.

2. Describe any three methods of water conservation.

Ans: Three methods of water conservation are as follows:

(i) Constructing dams and reservoirs to regulate supply of water to the fields, as well as to enable generation of hydroelectricity.

(ii) Judicious use of water in our day-to-day life.

(iii) Rainwater harvesting should be done by storing rainwater and recharging groundwater.

3. What is the purpose of soil conservation?

Ans: The purpose of soil conservation is to prevent soil erosion, maintain soil fertility, and protect natural resources such as water and biodiversity. It helps sustain agricultural productivity, preserves ecosystems, and mitigates the negative impacts of erosion on land and water quality.

4. State any three ways by which we can save energy.

Ans: Here are three ways to save energy:

(i) Switch to Energy-Efficient Appliances: Upgrading to energy-efficient appliances can significantly reduce energy consumption.

(ii) Use Natural Light: Utilize natural light during the day by opening curtains or blinds instead of relying solely on artificial lighting.

(iii) Unplug Electronics When Not in Use: Even when turned off, many electronics still consume energy. Unplugging them when not in use can help save energy.

A. Multiple Choice Question:
