Global Warming

Question 1

how do greenhouse gases retain heat?

Answer 1

their molecular polarity makes them lopsided and bounce around; the infrared waves get trapped in between them and warms up the environment.

Question 2

how global warming affects ice

Answer 2

declining sea ice; melting of ice alters the salinity of oceans (land and sea ice mix), impacting density and current. permafrost (frozen rock and soil) melt and release methane gas into the atmosphere.

Question 3

how global warming affects the sea

Answer 3

rising sea levels due to thermal expansion, threatening to low coastal islands. ocean acidification due to increase in carbon dioxide.
