Answer:
B. Geothermal refers to heat sources on the Earth’s crust
Explanation:
- The geothermal energy is the heat that is derived from the storing of energy that creates by the earth's temperature and the earth's crust is origin for this type of energy along with the radioactive decay of the elements of the crust.
- <u>Thus said to be earth's internal heat and needs to be trapped as it can get lost during the formation stages. </u>
- The temperature that occurs at the earth's core and the metal zone reaches up to 4000°C and thus the high temperature causes the rocks to melt and give rise to the temperature in the plastic mantle to get activated by the convection currents that reach the surface.
- Some examples of this geothermal energy are those of the hot spring and the rising lava or the magmas.
The sum of factors that add up to a community’s quality of life. This can include the built and natural environments, economic prosperity, social stability, educational opportunity, and entertainment and recreation possibilities.
Answer:
There are total 13 countries which equator passes through. Basically two of them are Congo and Brazil.

3. Congo and Brazil, are the countries whose major latitude and longitude go through equator.
Answer: 1- Option (D)
2- Option (A)
Explanation:
The green house gases plays a significant role in the earth's global temperature. In absence of green house gas, the earth would have been very much cold and life would would be difficult to exist. The average global temperature would have been about -15°C to 25°C. So the most favorable answer given here is that the<u> earth's temperature would have decrease by about 60°C</u>.
<u>Carbon dioxide (CO₂) is not the most abundant green house gas</u>. It is the second most abundant. The present composition of CO₂ in the atmosphere is about 0.04% by volume. A small increase in the CO₂ level, can lead to a global rise in the temperature. Hence, <u>the above statement is false.</u>
