- Archipelago
- A cluster, chain, or collection of scattered islands surrounded by a body of water.
- Isthmus
- A narrow strip of land bordered by water on two sides that connects two larger land masses.
- Strait
- A naturally formed, narrow waterway that connects two larger bodies of water.
- Delta
- A wetland landform formed by the deposition of sediment carried by a river at its mouth.
- Plateau
- A broad, elevated land area that rises sharply above the surrounding land on at least one side.
- Peninsula
- A piece of land almost entirely surrounded by water, remaining connected to a mainland.
- Fjord
- A deep, narrow sea inlet with steep sides or cliffs, carved by glacial activity.
- Canyon
- A deep gorge typically flanked by steep cliffs, usually carved over time by a river.
- Tributary
- A freshwater stream or river that flows into a larger stream, main river, or lake.
- Estuary
- A partially enclosed coastal body of water where freshwater from rivers mixes with ocean saltwater.
- Basin
- A depression or dip in the Earth surface, or the entire area drained by a river system.
- Alluvial Plain
- A flat landform created by the deposition of sediment over a long period by rivers coming from highlands.
- Latitude
- The angular distance measured in degrees north or south from the equator.
- Longitude
- The angular distance measured in degrees east or west of the Prime Meridian.
- Equator
- The imaginary line circling Earth at zero degrees latitude, dividing it into Northern and Southern Hemispheres.
- Prime Meridian
- The internationally recognized reference line at zero degrees longitude running through Greenwich, England.
- Topography
- The detailed mapping and description of the physical features, shape, and relief of an area.
- Oasis
- An isolated, fertile area in a desert environment supported by an underground freshwater source.
- Tundra
- A vast, flat, treeless Arctic and subarctic biome with frozen subsoil known as permafrost.
- Taiga
- The extensive subarctic evergreen coniferous forest zone south of the tundra.
- Savanna
- A rolling grassland biome with scattered trees, characterized by distinct wet and dry seasons.
- Steppe
- A dry, grassy, semi-arid plain without trees, typically found in temperate continental interiors.
- Rain Shadow
- A dry area on the leeward side of a mountain range that receives very little precipitation.
- Continental Shelf
- The edge of a continent that lies submerged under relatively shallow ocean waters.
- Atoll
- A ring-shaped coral reef, island, or chain of islands surrounding a central body of water called a lagoon.
- Lagoon
- A shallow body of protected water separated from a larger sea by barrier islands or coral reefs.
- Moraine
- A mass of rocks, soil, and sediment carried and deposited along the margins of a glacier.
- Permafrost
- A layer of soil or rock that remains completely frozen for at least two consecutive years.
- Watershed
- An area of land that channels rainfall and snowmelt into distinct creeks, rivers, and common outlets.
- Meander
- A winding curve, loop, or bend in a river or freshwater stream course.
- Oxbow Lake
- A U-shaped body of water formed when a wide meander from a river is cut off, creating a freestanding lake.
- Cape
- A headland or promontory of large size extending into a body of water, usually the ocean.
- Gulf
- A deep inlet of the sea almost surrounded by land, with a relatively narrow mouth.
- Bay
- A broad, curved inlet of water where the land curves inward, typically smaller than a gulf.
- Mesa
- An isolated flat-topped elevation with steep slopes, larger than a butte but smaller than a plateau.
- Butte
- A solitary, steep-sided hill with a small, flat top, formed by differential erosion.
- Gorge
- A narrow valley with steep, rocky walls, typically narrower and steeper than a canyon.
- Glacier
- A persistent, thick mass of compacted snow and ice that slowly deforms and moves under its own gravity.
- Caldera
- A large depression formed when a volcano erupts and subsequently collapses into its emptied magma chamber.
- Rift Valley
- A lowland region that forms where Earth tectonic plates move apart or rift.
- Tectonic Plate
- A massive, irregularly shaped slab of solid rock composed of continental and oceanic lithosphere.
- Subduction Zone
- A convergent boundary where one tectonic plate sinks beneath another into the Earth mantle.
- Cartography
- The science, art, and technique of compiling, designing, and producing maps and globes.
- Drainage Divide
- An elevated topographic boundary that separates neighboring drainage basins.
- Aquifer
- An underground layer of water-bearing permeable rock, rock fractures, or unconsolidated materials.
- Sound
- A wide sea or ocean inlet that is larger than a bay and deeper than a bight, often separating islands.
- Bight
- A wide, shallow bend, curve, or indentation along a coastline.
- Alluvium
- Loose clay, silt, sand, or gravel deposited by running water in a stream bed or floodplain.
- Karst
- A distinctive topography formed from the dissolution of soluble rocks like limestone, creating sinkholes and caves.
- Sinkhole
- A depression or hole in the ground caused by the collapse of the surface layer over an underground cavity.
- Endorheic Basin
- A closed drainage basin that retains water and allows no outflow to other external bodies like rivers or oceans.
- Coriolis Effect
- The apparent deflection of moving air and water caused by the rotation of the Earth.
