What type of climate is characterized by a small annual temperature range and high precipitation levels?

A maritime climate is characterized by a small annual temperature range and high levels of precipitation. This climate typically occurs in coastal regions where the influence of the ocean moderates temperature extremes. As a result, these areas experience milder winters and cooler summers compared to continental climates, which are influenced more strongly by land. The proximity to large bodies of water contributes to greater humidity and more consistent precipitation throughout the year.

In maritime climates, the consistent moisture and reduced temperature fluctuations create a conducive environment for diverse ecosystems. This characteristic stands in contrast to other climate types such as continental, which has a larger temperature variation due to its distance from oceans, or desert climates that are defined by low precipitation and can have extreme temperature swings. Tropical climates, while also having high precipitation, exhibit high temperature ranges that do not align with the characteristics of maritime climates. Therefore, the defining traits of a maritime climate make it the correct answer.
