Coastal communities often experience milder winters and cooler summers than further inland because of which of these factors?
a.
ocean winds blow consistently, providing a cooling effect
b.
they are always located at sea level, where temperatures are milder
c.
oceans absorb heat more slowly, which has a cooling effect on land
d.
oceans absorb heat more quickly, taking heat away from the land

D.  oceans absorb heat more quickly, taking heat away from the land

Explanation:

During summer when heat rises, sea water absorbs heat slowly due to the nature of its heat capacity. The land area around the beaches will warm rapidly. This difference in heat between land area close to the sea and the sea water causes movement of cool sea breeze to move to the land area.

The  reverse is the case during winter. Land area in winter loses heat rapidly and therefore, they cool while the sea becomes warm as it does not lose heat easily. The cold land breeze then moves to the ocean while the warm sea breeze moves to the land as a result of convection.
