Do coastal areas get more rain than inland areas?

So on average coastal areas get more rain than inland areas. Most of the moisture in the air gets there by way of evaporation of sea water. Some moisture does result from the evaporation of fresh water on the land of course, but not a lot, compared to the amount that comes from the oceans.

Why does it rain on land but not on the ocean?

Some moisture does result from the evaporation of fresh water on the land of course, but not a lot, compared to the amount that comes from the oceans. When warm moist air moves from over the sea onto land by the wind, the closer to the coast, the more moisture available to condense and fall as rain.

Why do different regions of the world have different rainfall patterns?

There are a range of reasons for differing rainfall patterns: Desert areas (most lie between 15° and 35° north and south of the equator) have limited rainfall as they receive sinking, dry air from high pressure systems.

What happens to the rain when it moves inland?

When moist, humid air moves in from a large body of water like an ocean, it moves inland and rains itself out over one half. Then, when it travels over a mountain range, it dries itself out. As a result, once it passes into the other half, all the rain is gone and the winds are dry.
