Multiple choice evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

To meet energy crisis what other sources can be exploited?

  2. Water

  3. Nuclear

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The wind, water, and nuclear energy are renewable forms of energy resources. These reserves once consumed can be replenished again. When there is an energy crisis, due to the reduction in the number of energy reserves, there will be an increase in the use of renewable resources. These energy resources can be exploited for the production of energy when there are no other resources available. 

Thus, the correct answer is option D. 

Multiple choice evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

Greatest problem in the water conservation is to reduce the amount of

  1. Ground water

  2. Precipitation

  3. Evaporation

  4. Run off water
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Evaporation from water reservoirs in hot arid climates causes a loss of 10 vertical feet a year. This water loss can be controlled by construction of reservoirs with greater water depth and concentration of water into single reservoir. Also wind blowing across the surface of water reservoir causes additional evaporation. A windbreak helps to conserve water. Thus the correct answer is option C.

Multiple choice evs wonderful world of bholu aquatic habitat life inside water animal and habitat

Animals that live in both land and water condition is called as

  1. Terrestrial

  2. Aquatic

  3. Amphibious

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Amphibians spend their lives in water and on land. There are more than 4,000 different kinds of amphibians. Members of this animal class are frogs, toads, salamanders, newts, and caecilians or blindworms.
Before amphibians reach adulthood, they first experience a larval stage, where they breathe primarily through their gills. When they get older, they start to breathe through their lungs, which allows them to live on land. Hence, it is necessary for amphibians to live in both land and water.
So, the correct answer is Amphibious.
