Which term refers to land projections extending into the water that are longer than capes?

The term referring to land projections extending into the water that are longer than capes is "peninsulas." A peninsula is a landform surrounded by water on most sides but still connected to the mainland, typically having a broader stretch of land compared to a cape. Capes are typically narrower projections of land, whereas peninsulas can vary significantly in size and often encompass larger areas.

Islands, while related to land and water, are entirely surrounded by water and do not connect back to the mainland. Bays refer to bodies of water partially enclosed by land but do not describe land projections. Coastlines represent the boundaries of land and water but don’t specifically define any land formations that project out into the water like a peninsula does. Therefore, the definition of a peninsula aligns precisely with the concept of land extending into the water longer than capes do.
