Why is the climate different for locations in the interior as compared to the exterior of a large continent?

The climate in the interior of a large continent tends to be more extreme and variable compared to coastal areas due to the distance from the moderating influence of the ocean. Oceans have a high heat capacity, absorbing and releasing heat slowly, which stabilizes coastal temperatures and creates milder climates. In contrast, inland areas experience greater temperature fluctuations, with hotter summers and colder winters, resulting in a more continental climate. Additionally, coastal regions often benefit from moisture and precipitation brought by ocean winds, while interior regions may be drier.
