Heat (infrared radiation) rises from the earth into the air. Greenhouse gases in the atmosphere hold onto this heat and become warm. (So the heat doesn't escape into space.) This warmth spreads out in all directions, including back down to earth, where it warms the land even more.

BeauLand surfaces heat up more quickly than water surfaces, leading to differences in temperature. This temperature contrast causes air to flow from areas of land to water and vice versa, creating breezes. Additionally, land surfaces tend to create more turbulence and local circulations in the atmosphere compared to smooth water surfaces.

What is the difference in albedo between water and land surfaces?
The difference in albedo between water and land surfaces is that water has a lower albedo, meaning it reflects less sunlight and absorbs more heat compared to land surfaces. Land surfaces have a higher albedo, reflecting more sunlight and absorbing less heat.
What factors affect water runoff?
Factors that affect water runoff include the slope of the land, soil type, land cover (such as vegetation or impervious surfaces), amount of precipitation, and human activities like urbanization or deforestation. These factors can influence how quickly water moves across the land surface and how much is absorbed by the ground.
Why are land surfaces heated more quickly?
Land surfaces heat up more quickly than water surfaces because soil has a lower heat capacity than water, meaning it requires less energy to raise its temperature. Additionally, land surfaces have a lower albedo, meaning they absorb more sunlight and convert it into heat. This combination of lower heat capacity and higher absorption of sunlight leads to land surfaces heating up more rapidly than water surfaces.
What are factors that affect runoff?
Factors that affect runoff include the amount and intensity of precipitation, soil type and permeability, slope of the land, land cover (such as impervious surfaces like pavement), and human activities such as urbanization and deforestation. These factors can influence how quickly water flows across the land surface and how much is absorbed into the ground versus becoming runoff.
What two types of surface on Earth are most important for absorbing solar energy and keeping the planet warm?
The two types of surfaces on Earth that are most important for absorbing solar energy and keeping the planet warm are land and water. Land surfaces absorb and release heat quickly, while water surfaces have a higher heat capacity and can store more heat, regulating temperatures and influencing weather patterns.
