All terms in this list:

Abyssal Plain: Begins where the continental slope flattens. Flat or gently sloping, smooth area of the ocean floor.

Barrier Islands: Islands are pieces of land surrounded by water on all sides. Islands with sandy beaches.

Beaches: The shoreline, or coast, is the area where the land meets the ocean. Some shorelines are rocky. Shorelines made of sand.

Canyon: Canyons have steep walls and are formed by erosion and weathering of soft rock caused by the movement of water in rivers. Deep valley with high, steep sides.

Conservation: The wise use of natural resources is called conservation.

Conservation Efforts: Human activities that help to keep the natural resources of Earth available and clear of pollution are conservation efforts.

Constructive Process: Processes that create landforms.
(deposition, landslides, volcanic eruptions, floods)

Continental Shelf: The edges of the continents slope down from the shore into the ocean. The part of the continent located under the water is known as the continental shelf.

Continental Slope: The steep slope where the continental shelf drops to the bottom of the ocean floor

Currents: A body of water or air moving in a definite direction, especially through a surrounding body of water or air in which there is less movement.
"ocean currents"

Delta: Deltas form from the deposition of the sediment carried by the river as the water flow leaves the mouth of the river. Deltas are shaped like a fan.

Deposition: Deposition is the dropping, or depositing, of sediments by water, wind, or ice.

Destructive Processes: Processes that destroy landforms
(weathering, erosion, landslides, volcanic eruptions, earthquakes, floods)

Drainage Basin: An area of land where all surface water from rain, melting snow, or ice converges to a single point at a lower elevation, usually the exit of the basin, where the waters join another body of water, such as a river, lake, reservoir, estuary, wetland, sea,

Earthquake: Earthquakes are vibrations on Earth’s surface caused by sudden movement along a fault, or a break in Earth’s surface.

Erosion: Erosion is the movement of sediments and soil by wind, water (floods), ice (glaciers), and gravity.

Estuaries: The area where a river meets the ocean and all rivers flow into the oceans. Estuaries have a mixture of freshwater and saltwater.

Floods: Floods occur when a large amount of water covers land that is usually dry

Fossil Fuels: (such as coal, oil, or natural gas) that is formed in the earth from dead plants or animals.

Hurricane: A storm with a violent wind, in particular a tropical cyclone

Inlets: Inlets are the water-filled spaces between the barrier islands.

Landslides: Landslides are mass movements of land due to gravity.

Mid-Ocean Ridge: On the bottom of the ocean, there is a central ridge, or mountain range, that divides the ocean floor into two parts. These underwater volcanic mountains are known as the mid-ocean ridge.

Mountain/ Mountain Range: Land which rises high above the ground

Plains: Wide, flat areas of land

Pollution: Pollution is anything that harms the natural environment.

Rift zone: In the center of the highest part of the mid-ocean ridge is a narrow trench called a rift. Underwater volcanic activity that adds mountains to either side of the mid-ocean ridge occurs at the rift zone.

Seamount/ Volcanic Island: A large underwater mountain

Storm: A violent disturbance of the atmosphere with strong winds and usually rain, thunder, lightning, or snow.

Tides: The alternate rising and falling of the sea, usually twice in each lunar day at a particular place, due to the attraction of the moon and sun.

Trench: Ocean trenches are the deepest part of the ocean basin and are deeper than any valley found on land.

Tsunami: A long high sea wave caused by an earthquake, submarine landslide, or other disturbance.

Valley: V-shaped valleys are formed by the effects of running water.Low land between hills or mountains

Volcanic Eruptions: Volcanoes are mountains with openings in Earth’s crust through which magma, gases, and ash reach Earth’s surface.

Volcano: An opening in the surface from which lava flows.

watershed: All of the land that water flows over or through before reaching a lake or river.

waves: A long body of water curling into an arched form and breaking on the shore. A moving swell or ridge of water that carries energy.

weathering: Weathering is the processes that break down rocks at or near the surface of the earth.
