A. The rate of photosynthesis must be greater than the rate of respiration
Mesosphere is the layer after stratosphere, which is after troposphere, as seen from Earth in the direction of Space.
It starts at 60 km and ends at 120 km, after which comes the termosphere.
So we're looking for a line that's closest to 100 km, and this is the shortest line, A.
Answer:
D. Solar radiation heats the asphalt; the air immediately above is heated through conduction; the warm air rises in free convection.
Explanation:
As the parking lot is exposed to the sun, on a sunny afternoon, we can consider that the sun is radiating with high intensity in this environment, causing the asphalt to be strongly heated. In this case, the air that comes in contact with the asphalt ends up being heated, because the heat of the asphalt is transmitted by the air through the process called conduction, which is the heat transmitted by the agitation of the molecules.
The heated air becomes less dense, that is, it becomes lighter and this causes it to rise, while the cold air is more dense and descends, coming into contact with hot asphalt and also heating up. In that case, a heat transfer called convection occurred.
