how does earths natural greenhouse effect work?
insulating the planet by trapping heat and preventing it from leaving the atmosphere
increasing the amount of heat generated by the earths core
decreasing the amount of solar radiation entering the atmosphere

where do the co2 emissions resulting from human activities go?
30% to the atmosphere and 40% to the oceans and 30% to terrestrial ecosystems
10% to the atmosphere and 40% to the oceans and 50% to terrestrial ecosystem
100% to the atmosphere
50% to the atmosphere and 50% to the oceans
60% to the atmosphere 20% to the ocean and 20% to terrestrial ecosystems

Explanation:

For Question 10, the greenhouse effect works by certain gases in the atmosphere (greenhouse gases) trapping heat radiated from the Earth's surface, insulating the planet. For Question 11, a significant portion of human - generated CO2 emissions (about 30 - 40%) goes to the atmosphere, around 40% to the oceans, and 30% to terrestrial ecosystems.

Answer:

Question 10: Insulating the planet by trapping heat and preventing it from leaving the atmosphere
Question 11: 30% to the atmosphere and 40% to the oceans and 30% to terrestrial ecosystems
