Answer:
a. standing in a breeze after getting out a pool in summer is an example of evaporative cooling .
Explanation:
As in summer season , the wind will be warm and dry , and after coming out of the pool the body will have a layer of water droplets and these water droplets will come in contact with the warm air , the water droplets will evaporate and in turn causes a cooling effect .
Evaporation causes cooling , because , during the process of evaporation the liquid particles absorb some energy from its surrounding , hence , due to this absorption of energy the surrounding turns cooler.
Answer:
There are three main sources of heat in the deep earth: (1) heat from when the planet formed and accreted, which has not yet been lost; (2) frictional heating, caused by denser core material sinking to the center of the planet; and (3) heat from the decay of radioactive elements.

<u>Answer:
</u>
The process of thick sediment layers to "accumulate" along the "boundaries of continental and oceanic plates" is called Subduction.
<u>Explanation:
</u>
- During a marine transgression, sea level raises high compared to land level resulting in floods. These are triggered during climate changes, ice-age, isostatic movements.
- Subduction occurs at the tectonic plates where one plate is moves under another forcing to sink into Earth’s mantle due to the gravitational force.
- The plates are continental and oceanic in the zone of lithosphere. The rate of subduction is usually seven to 8 centimetres per year.
- Marine regressions are opposite to transgressions where sea levels fall compared to land levels.
- Glaciation is the interval of time within an ice-age. The current glacier period is of Holocene.
There are three mountains: the Sierra Madre Occidental, the Sierra Madre Oriental, and Sierra Madre del Sur.
