temperatures don't vary.
The sea surface temperature in the equatorial pacific ocean. El Niño is characterized by unusually warm temperatures and la Nina by unusually gets cool temperatures in the equatorial pacific. El Niño can be very destructive and can cause floods, It is very dangerous to cities.
It provided trade routes, and it made Europe very wealthy.
Insolaration (energy of the Sun reaching the ground) and nearness to open water (the ocean).
The reason is because of Ocean/Surface Currents. The cities are in the same hemisphere, but they don't receive the same ocean current. Some ocean currents are warm, while some are cold.The Ocean/Surface Currents have an effect on the air temperatures, too. Another reason is because of latitude. When a city is at a higher latitude the air expands and makes the temperature colder ,while if the latitude is lower the air loses moisture and the temperature heats up.
Ocean temperatures change on a seasonal basis, but there are other factors at play which complicate when, and how, and by how much it changes.
Yes, warmer temperatures and greater ocean acidification (carbonic acid from carbon dioxide) is bleaching and killing the coral reefs.
Because the sun reflects off the ovean and on to the shore, increasing the amount of sun that the land usually gets.
true
Land heats more rapidly and to higher temperatures than water does, and cools quicker to lower temperatures than water. Ocean temperatures are more moderate than land temperatures.
B. Ocean currents affect temperatures on land.
It has to be the Summer. In Winter, the ocean currents are WARM compared to coastal temperatures.
About 34 degrees
