| Term | Definition |
|---|---|
| Mountain | Large landforms that rise prominently above their surroundings, typically having a peak and steep slopes. They are formed through geological processes such as tectonic plate movements and volcanic activity. |
| Hill | Elevated landforms that are smaller and less steep than mountains. They have a rounded summit and are often formed by erosion or sediment deposition. |
| Desert | Barren, dry regions with very little precipitation, sparse vegetation, and extreme temperature variations. |
| River | A natural watercourse, usually a stream of fresh water, that flows another body of water like an ocean, sea, lake, etc. |
| Gulf | A large area of sea partially enclosed by land, typically with a narrower opening to the ocean. |
| Sea | A large body of saltwater that is smaller than an ocean and is partially enclosed by land. They are often connected to oceans but are distinct in their geographic boundaries. |
| Delta | A landform where a river meets a body of water, such as a sea or lake, and deposits sediment, forming a typically triangular or fan-shaped area. |
| Cataract | A large waterfall or a series of waterfalls, often characterized by a steep drop and turbulent flow. |
| Oasis | A fertile area in a desert where water is available from a natural spring or well, allowing for the growth of vegetation and supporting life. |
| Valley | A low area of land between hills or mountains, often with a river or stream flowing through it. They are typically formed by erosion from glaciers, rivers, or tectonic activity. |
