Landform
A feature on the surface of Earth such as a mountain, hill, dune, ocean, hoodoo, or river.
Delta
A triangular landform where a river empties into another body of water. Caused by deposition.
Canyon
A deep gorge in the surface of Earth formed by the erosion of moving water and sand over millions of years. It has a long and wide top and a narrow base.
Sand Dune
Hills formed by wind blowing and depositing sand.
Weathering
The breaking down of rock into smaller particles from the effects of wind, water, and ice.
Erosion
The movement of sediment causing a gradual wearing down of something by wind, water, ice.
Deposition
The build-up of land by the settlement of sediment and soil in a new location.
TERM
U-shaped Valley
DEFINITION
A type of valley created by ice weathering and erosion (glacier).
LOCATION
V-shaped Valley
A type of valley created by water weathering and erosion (river).
Glacier
A giant slab of moving ice.
Colorado River
The river responsible for carving away the rock in Arizona to create the Grand Canyon.
Fossil Fuels
A natural, non-renewable resource such as coal, oil, or natural gas, formed over millions of years from the remains of living organisms.
Coal
A solid fossil fuel that is formed from the concentrated remains of plants over millions of years.
Oil
Also called petroleum, this is a flammable liquid produced from remains of marine organisms buried under layers of sediments for millions of years.
Natural Gas
A flammable material, without a definite form, produced from remains of marine organisms buried under layers of sediment found near oil deposits.
Pressure
Forced of objects pushing on other objects.
Sedimentary Rock
Layers of rock formed when sediment is deposited and then compacted and cemented over time. Heat and pressure causes the layers to cement together.
Organic Matter
The waste and remains of plants and animals.
Compaction
Bits of rock that are pressed tightly together as layers of rock form on top of each other.
Cementation
Over time, particles of sediment begin to stick to each other or bond to one another.
TERM
Mountain
DEFINITION
An uplift of land that stretches over the land and forms a peak. Can be formed by tectonic plates colliding into each other or a volcano.
