Melting sea ice to reveal darker water.
Replacing tundra with more rapid growth.
Melting glaciers to reveal darker soil.
Changing migration patterns for sea life.
Q; Which are ways in which heat energy leaves the surface of land masses? Select the three correct answers.(2 points)
conduction to air, which then rises in convection
evaporation
plant growth
glacial motion
animal activity
radiation of infrared energy
An asphalt surface absorbs (less/more) solar energy than a cement surface. This difference is chiefly due to differences in (moisture/texture/color).

I have no clue I came for help aswell
can somebody PLS help
A: Melting sea ice to reveal darker water and melting glaciers to reveal darker soil. The Arctic's albedo is altered by these changes in surface coloration.
A: The three correct answers for heat energy leaving the surface of land masses are: conduction to air, which then rises in convection; evaporation; and radiation of infrared energy.
An asphalt surface absorbs more solar energy than a cement surface. This difference is chiefly due to differences in color. So, the answer is "more" solar energy and "color". Asphalt tends to have a darker color than cement, resulting in greater absorption of solar energy.
A: The correct answers for the first question are "Melting sea ice to reveal darker water" and "Melting glaciers to reveal darker soil". Global warming causes the Arctic ice to melt, which leads to the exposure of darker surfaces such as water and soil. These darker surfaces have lower albedo (reflectivity), causing them to absorb more solar radiation and contribute to further warming in the region.
For the second question, the correct answers are:
1. "Conduction to air, which then rises in convection": Heat energy can transfer from the land surface to the surrounding air through conduction, and then rise through convection.
2. "Evaporation": Heat energy can leave the surface through the process of evaporation, where liquid water changes into water vapor.
3. "Radiation of infrared energy": Heat energy can be radiated as infrared energy from the land surface.
An asphalt surface absorbs more solar energy than a cement surface. This difference in absorption is primarily due to differences in color. Asphalt surfaces are typically darker in color compared to cement surfaces, which means they have lower albedo (reflectivity) and tend to absorb more solar energy. Moisture and texture can also play a role, but in this case, color is the main factor.
