isthmus
Isthmus is a narrow strip of land that connects two larger land areas and separates two bodies of water. It acts as a natural bridge between regions. Isthmuses can vary in width and may include hills, plains, or forests. They are often important routes for travel. Isthmuses are found in different parts of the world, […]
fjord
Fjord is a long, narrow inlet of the sea with steep sides or cliffs. It often stretches far inland from the coast. Fjords usually have deep water and are surrounded by high land. The sides can be rocky and rise sharply from the water. Fjords are found mainly in regions such as Norway, Greenland, Canada, […]
watershed
Watershed is an area of land where all water drains to a common river, lake, or ocean. Rain and melted snow flow across the land into streams and rivers within this area. Watersheds can be small or very large, covering wide regions. Every piece of land is part of a watershed. Watersheds are found across […]
basin
Basin is a low area of land where water collects. It can be surrounded by higher land that directs water into it. Basins may hold rivers, lakes, or underground water. Some basins are large regions, while others are smaller and more local. Basins are found worldwide on land and under oceans, such as river basins […]
coastline
Coastline is the boundary where land meets the ocean or sea. It can include features such as beaches, cliffs, bays, and estuaries. Coastlines can be straight or irregular, with many shapes and patterns. Waves and tides often affect the shoreline. Coastlines are found along continents and islands around the world. They change over time due […]
shoreline
Shoreline is the edge where water meets land along oceans, seas, lakes, or rivers. It can include sand, rocks, or soil. Shorelines may be smooth or uneven, depending on the landscape. Waves and currents often shape the edge of the land. Shorelines are found around the world along all types of water bodies. They can […]
cave system
Cave system is a network of connected underground caves and passages. These spaces can include tunnels, chambers, and openings that link together. Some cave systems are very large and extend for many kilometers. They may have features such as rock formations, underground rivers, and hidden pathways. Cave systems are found in many regions, especially in […]
karst landscape
Karst landscape is a type of landform that includes features such as caves, sinkholes, and underground drainage systems. It forms in regions where the rock can be dissolved by water, such as limestone. The surface may have uneven ground, holes, and hidden openings. Water often flows below the surface instead of in rivers. Karst landscapes […]
ice sheet
Ice sheet is a very large, thick layer of ice that covers a wide area of land. It can be several kilometers thick and spread across large regions. Ice sheets are made from layers of snow that have built up and compressed over time. They move slowly across the land beneath them. Ice sheets are […]
gulf
Gulf is a large area of water that is mostly surrounded by land with a narrow opening to a sea or ocean. Gulfs are usually deeper and more enclosed than bays. They can extend far into the land. Gulfs often have important coastal regions around them. Gulfs are found along coastlines worldwide, such as the […]
