Understanding the terminology used to describe the Earth’s surface is fundamental to geography. Below is a comprehensive list of key landforms, water bodies, and terrestrial features, along with their precise definitions.

Landforms and Terrestrial Features

  • Mountain

    A large natural elevation of the earth’s surface.

  • Hill

    A naturally raised area of land, smaller than a mountain.

  • Valley

    A low area of land between hills or mountains.

  • Plain

    A large area of flat land.

  • Plateau

    An area of relatively level high ground.

  • Cliff

    A steep rock face, especially at the edge of the sea or a river.

  • Canyon

    A deep gorge, typically one with a river flowing through it.

  • Forest

  • Glacier

    A large mass of ice moving slowly down a slope or valley.

  • Ravine

    A small, narrow, steep-sided valley.

  • Volcano

    An opening in the earth’s crust that allows molten rock and gases to escape.

  • Foothill

    A low hill at the base of a mountain.

  • Gorge

    A narrow valley between hills or mountains, typically with steep rocky walls.

  • Highlands

    An area of high or mountainous land.

  • Lowlands

    Land at low elevation, usually flat.

  • Hillside

    The side of a hill.

  • Pasture

    Land covered with grass for grazing livestock.

  • Woodland

    Land covered with trees, less dense than a forest.

Water Bodies and Coastal Features

  • Coast

    The land next to the sea or ocean.

  • Beach

    A sandy or pebbly shore by the edge of the sea.

  • River

    A large natural stream of water flowing in a channel.

  • Lake

    A large body of water surrounded by land.

  • Waterfall

    A place where water flows over a vertical drop.

  • Swamp

    A wetland area with standing water and trees.

  • Meadow

    A field of grassland often filled with wildflowers.

  • Marsh

    A wetland dominated by herbaceous plants.

  • Archipelago

    A group or chain of islands.

  • Bay

    A broad inlet of the sea where the land curves inward.

  • Peninsula

    A piece of land almost surrounded by water or projecting into a body of water.

  • Watercourse

    A channel through which water flows, such as a river or stream.

  • Swell

    A gentle, rolling movement of the sea.

  • Fjord
