Why is the exosphere hotter than the troposphere? A. The exosphere is closer to earth's surface b. The troposphere loses its heat to the outer layers of earth's atmosphere c. The exosphere absorbs high-frequency, high-energy EMS waves d. The troposphere heats up the exosphere, causing it to have higher temperatures

clumped distribution, because you'de have all of the population gathered in a relatively small are.

it's the most common because it provides protection and a mate for reproduction

example: humans, seeweed, cattles, etc.

the answer is c because it is most logical.

the circled areas are referred to   as sunspots.   the sunspots are cooler than the   surrounding area.

sunspots are temporary phenomena on the photosphere of the sun that appear visibly as dark spots compared to surrounding regions. they correspond to concentrations of magnetic field flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
