Explanation / Answer

Amswer 87.

a- go into the ocean and sediments. The ocean is the world's largest sink (a place where Co2 is dissolved). The oceans can dissolve nearly 30 percent of the anthropoligical CO2. However if we can plant more trees then the avaible CO2 will decrease and hence the oceans will need to absorb less CO2 -slowing down the rate of global warming.

Answer 88:

b- decrease and warmer. Albedo is the amount of radiation reflected back.. the albedo of darker surfaces is always lower than of lighter surfaces since darker surfaces absorb more light and radiation. In this case the white snow will melt to make way for a darker surface (water) and absorb much more radiation causing the temperature to rise.

Answer 61:

d- energy from the earth has a different wavelenght than sunlight. The eart emits energy with a longer wavelenght. However, this answer is not compete since earth's energy does pass through the atmosphere since the radiation emitted by the earth are reflected to the atmosphere and space but it is just not comparable to the amount of radiation from the sun.
