Why do coastal areas have milder, less variable climates than inland areas?
A) Large bodies of water have high salt concentrations, and salt absorbs a large proportion of the light energy that would have warmed the land. B) Coastal areas are concentrated near the equator, which varies less than other parts of the globe in the angle at which the sun's light hits it. C) Because water is a good solvent, it is able to dissolve the photons in light, reducing their ability to heat or cool the land. D) Large bodies of water, especially oceans, can absorb huge amounts of heat from the sun during warm times of the year, reducing temperature increases on the land. Similarly, during cold times of year the ocean slowly cools, giving off heat that reduces the temperature drop on shore. E) There is no known reason why coastal areas have milder, less variable climates than inland areas.
