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:
verdade
Explicação:
A afirmação é verdadeira de que o estudo dos fundos marinhos trouxe evidências de que as cordilheiras oceânicas são regiões onde a nova crosta oceânica é formada. Essa nova crosta oceânica é formada nas cordilheiras do meio do oceano devido à erupção vulcânica no fundo do mar no processo de propagação do fundo do mar. Nas cordilheiras do meio do oceano, um novo fundo do mar é formado continuamente durante o processo de propagação do fundo do mar.
Answer: The release of methane from thawed permafrost
Explanation:
With increasing global warming, permafrost in the arctic is melting. The carbon and methyl clathrates present in permafrost escape into the atmosphere to form carbon dioxide and methane, both greenhouse gases.
In the Arctic, molecules of methane are trapped in ice crystals as methyl clathrates. When the temperature increases, these crystals release methyl clathrates which become methane when in contact with the atmosphere.
The cause of the increasing atmospheric
is due to the the thawing of dead organisms present in the permafrost. As the permafrost melts, these organisms decay and release
into the atmosphere.
Acid rain from Los Angeles changed the chemistry of the river, resulting in the death of many fish.Due to human activities in Los Angeles, pollution is not anymore shocking. The acid rain would be distributed to the river which would change the environment of the aquatic life.
Explanation:
