Why the temperature of the coastal region is moderate compare to the continental interior?

The temperature of coastal regions is moderate compared to the continental interior due to the influence of large bodies of water, such as oceans and seas. Water has a high specific heat capacity, meaning it can absorb and release heat slowly, leading to more stable temperatures. This results in cooler summers and milder winters in coastal areas, while continental interiors experience greater temperature extremes due to the land's quicker response to heating and cooling. Additionally, coastal breezes can help regulate temperatures further.
