Energy Resources and Storage Questions
-
Solar energy
-
Hydroelectric energy
-
Wind energy
-
Nuclear energy
B
Correct answer
Explanation
Hydroelectric energy causes the lowest carbon dioxide emission.
-
Generator
-
Transformer
-
Solar cell
-
Rheostat
-
Battery
D
Correct answer
Explanation
Rheostat is the variable resistance, i.e. we can vary the value of resistor using rheostat. Rheostat is not energy source. It is used only to increase or decrease the given voltage value in lab experiments. Option 4 is correct.
-
solar panels
-
windmills
-
dams
-
coal
D
Correct answer
Explanation
Coal is a fossil fuel that takes millions of years to form and cannot be replenished on a human timescale, making it a non-renewable energy source.
-
Natural gas
-
Petroleum
-
Coal
-
Wind
D
Correct answer
Explanation
Wind is a renewable resource because it is naturally replenished by atmospheric processes. Natural gas, petroleum, and coal are fossil fuels that take millions of years to form and are non-renewable.
-
Fish population
-
Natural vegetation
-
Coal deposits
-
Corn crops
C
Correct answer
Explanation
Coal is a fossil fuel formed over millions of years and cannot be replenished on a human timescale, making it a non-renewable resource. Fish, vegetation, and crops can reproduce and replenish themselves.
-
hydroelectric energy
-
geothermal energy
-
solar energy
-
biofuel energy
C
Correct answer
Explanation
Energy that comes from the sun is known as solar energy. Hydroelectric energy comes from water, and geothermal energy comes from the Earth's internal heat.
-
geothermal energy
-
hydroelectric energy
-
gasoline
-
biofuel
D
Correct answer
Explanation
Biofuel is a renewable energy source derived from organic matter (like plants) that can be used as a substitute for gasoline in vehicles. Geothermal and hydroelectric energy are not typically used to power individual cars.
-
biofuel
-
wind
-
petroleum
-
solar
C
Correct answer
Explanation
Petroleum is a fossil fuel and is considered a traditional, non-renewable energy resource. Biofuel, wind, and solar are all examples of alternative or renewable energy resources.
-
geothermal energy
-
natural gas
-
sunlight
-
wind energy
B
Correct answer
Explanation
Nonrenewable resources exist in finite amounts and cannot be replaced on a human timescale. Natural gas is a fossil fuel that takes millions of years to form, unlike sunlight, wind, or geothermal energy which are renewable.
-
Geothermal
-
Wind
-
The Sun
-
Gas
D
Correct answer
Explanation
Fossil fuels are formed from the remains of ancient organisms. Natural gas (often referred to as 'gas') is a fossil fuel, whereas wind, solar, and geothermal are renewable energy sources.
-
batteries
-
wind
-
water
-
the sun
D
Correct answer
Explanation
The sun provides the light energy that plants use for photosynthesis, which is the base of almost all food chains on Earth.
The most common sources of energy are:
-
wood and coal
-
petroleum and coal
-
LPG and cow dung
-
natural gas and wood
B
Correct answer
Explanation
Fossil energy like coal, lignite, petroleum and natural gas are most common sources of energy. These sources of energy are used to produce electricity, cook food, heat thermal engines etc.
From below which is the type of energy from sea?
-
Tidal Energy
-
Wave Energy
-
Ocean Thermal Energy
-
All of above
D
Correct answer
Explanation
Energy from the sea can be classified into three types:
1. Tidal energy - This energy is harnessed by building a dam and placing a turbine near the opening of the dam. By using the turbine, tidal energy of the sea is used to produce electricity.
2. Wave energy - Kinetic energy of the wave is used in generation of electricity.
3. Ocean thermal energy - Thermal difference between the cold ocean water and warm tropical surface water is used to generate electricity.
Waves are used to rotate ____________ to generate electricity. Fill in the gap.
-
Rotor of Dynamo
-
Turbine of dam
-
Wheel of wind mill
-
Armature of motor
A
Correct answer
Explanation
Waves are made to fall from a height on to the rotor of a turbine or dynamo to make them rotate. This mechanical energy is then converted to electrical energy.
The two different ways of harnessing energy from ocean are :
-
Tidal Wave, OTEC
-
Geothermal, wave energy device
-
Solar energy, point wave absorber
-
All of the above
A
Correct answer
Explanation
The two different ways of harnessing energy from ocean is Tidal wave and Ocean Thermal Energy Conversion (OTEC).
Answer (A) Tidal Wave, OTEC
