The answer is C, cooler by water. Those places in this region that are near the water generally have a Mediterranean climate. Further inland, those areas
adjacent to the Mediterranean climates are usually steppe (Precipitation is 10-25 inches of rain a year, Vegetation grasslands, few trees, can be cold or hot). The remainder of the region is a desert climate (Precipitation less than 10 inches a year, Vegetation from scrub plants and cactus to almost
nothing, can be cold or hot). Around 50% of the region is desert. However, Less than 10% of the land in the desert is sand. The rest of the desert is rocky and gravelly.
