Explain why coastal cities are more likely to have moderate temperatures than cities that are in the center of continents.

The coastal cities tend to have more moderate temperatures than the cities in the middle of the continental masses because they are heavily influenced by the sea.

The sea is a very important climatic factor in the coastal areas. It makes the summers cooler, the winters warmer, and the variation of the temperature is much lower. This is due to the thermal properties of the water, which cools of relatively slow, and warms up relatively slow as well.

The parts deeper into the continents are not influenced by the sea, so they are much drier, have very hot summers, and very cold winters. That is due to the thermal properties of the land, which cools off and warms up very quickly.
