What is/are the energy available from sea in the below options?
Report Question
0%
Tidal energy
0%
Wave energy
0%
Ocean thermal energy
0%
All of above
Explanation
Tidal energy - Tides form in the ocean due to the gravitation pull of the moon. Tidal energy is a form of hydropower that utilizes energy from tides to produce electricity.
Wave energy - Waves in the sea are used to run the turbines to generate electricity.
Ocean thermal energy - Water at the sea surface is hotter than the water at its depth. This temperature difference is used to produce energy.
Hence, A, B, and C all the energies are available from the sea.
So, the correct option is D.
Find odd one out:
Report Question

Hydroelectric
0%
Nuclear
0%
Solar
0%
Geothermal
Explanation
Geothermal energy is described from heated ground water.
Choose the correct statement.
Report Question
0%
Biomass energy causes no pollution.
0%
Biomass energy causes heavy pollution.
0%
Biomass energy causes less pollution as compared to conventional sources of energy.
0%
Biomass energy is costly.
Explanation
Bio-mass is the source of fuels coming from plant and animal products like wood and cow-dung. Decomposition of bio-mass gives bio-gas which
does not produce pollutants like coal and petroleum do.
Bio-gas is an excellent fuel as it contains up to 75% methane. It burns without smoke, leaves no residue like ash in wood, charcoal and coal burning. Its heating capacity is high.
However, its combustion still produces some pollutants, though they are less than those produced by burning fossil fuels.
Tidal energy works using:
Report Question
0%
average of sea levels of high and low tides.
0%
resisting the formation of tides.
0%
difference in sea levels between high and low tides.
0%
using heat energy in tides.
Explanation
Due to gravitational pull of the Moon (and the Sun), sea level changes and high tides and low tides are formed. Difference in sea levels between high tides and low tides gives us tidal energy.
Electricity production from wave energy requires:
Report Question
0%
Strong waves
0%
Mild waves
0%
Either (A) or (B)
0%
None of the above
Explanation
Wave energy would be a viable proposition only where waves are very strong.
Wave power is the capture of energy of wind waves to do useful work, for example, electricity generation, water desalination, or pumping water. Wave-power generation is not a widely employed commercial technology compared to other established renewable energy sources such as wind power, hydropower, and solar power.
State True or False :
Geothermal energy can be used to produce electricity.
Report Question
0%
True
0%
False
Explanation
Geothermal power plants use steam to produce electricity. The steam comes from reservoirs of hot water found a few miles or more below the earth's surface. The steam rotates a turbine that activates a generator, which produces electricity.
The biggest drawback of tidal energy is:
Report Question
0%
it causes excessive pollution in oceans
0%
locations where it can be harnessed are limited
0%
the height difference of tides is low and much energy is not produced
0%
it needs a lot of manpower
Explanation
Tidal energy can be harnessed only at very limited locations.
Some of the disadvantages of tidal energy are:
1. High tidal power plant construction cost.
2. Negative influence on marine life forms.
3. Location limits.
Ocean thermal energy is based on:
Report Question
0%
Temperature difference across the sea.
0%
Temperature difference between surface and depths of sea.
0%
High temperature at depth of sea water.
0%
Temperature rise in climate caused by sea water.
Explanation
The water at the surface of the sea or ocean is heated by the Sun while the water in deeper sections is relatively cold. This difference in temperature is exploited to obtain energy in ocean-thermal-energy conversion plants.
Common source of energy used for cooking in rural parts of India is:
Report Question
0%
Sun
0%
Coal
0%
Wood and animal dung
0%
None of the above
Explanation
Wood and animal dung are the major sources of energy for cooking in rural areas. It is readily available and is a cheap form of energy, while solar energy is not abundantly used because it's difficult to harness solar energy and coal has not cost-efficient.
What are the disadvantages of thermal power plants?
Report Question
0%
Heavy environmental pollution
0%
They need to be set up near coal or oil fields
0%
Depletion of ground natural reserves and fossil fuels
0%
All of the above
Explanation
Thermal power plants:
1. Burns huge amounts of coal to produce steam by boiling water causing pollution.
2. Transportation of coal is costlier than transmission of electricity.
3. Extraction of coal and oil depletes ground natural reserves.
Tidal energy is harnessed by:
Report Question
0%
transporting sea water to a close dam.
0%
constructing a submerged dam.
0%
constructing a dam across a narrow opening to the sea.
0%
constructing an overhead dam.
Explanation
Difference in sea-levels due to tides during different times of day gives us tidal energy. Tidal energy is harnessed by constructing a dam across a narrow opening to the sea. A turbine fixed at the opening of the dam converts tidal energy to electricity.
