Final answer:
Coastal areas in the continental United States generally have a more moderate climate compared to the interior due to the influence of warmer air from the oceans, coastal upwellings, and higher elevation in the interior.
Step-by-step explanation:
The reason that coastal areas in the continental United States generally have a more moderate climate than areas in the interior of the country can be attributed to several factors. One important reason is that coastal areas are influenced by warmer air from the oceans. The oceans collect and store vast amounts of solar energy, which moderates the climate along the coast. The slower heating and cooling of water compared to land also contributes to the more moderate climate.
Another factor is that coastal areas benefit from coastal upwellings, which influence the land along all the coasts. Upwellings bring cold, nutrient-rich waters from the ocean depths to the surface, which can impact temperature and precipitation patterns in coastal regions.
Additionally, interior areas being at a higher elevation plays a role in the differences in climate. Higher elevations tend to have cooler climates due to decreased air pressure and the associated drop in temperature.
