Landform
Large elevation formed by tectonic movement.
Mountain
Land built by river sediment at its mouth.
Delta
Wearing away of rock and soil by wind, water, or ice.
Erosion
Removes rock and minerals, changing land shape.
Mining
What is a delta, and how is it formed?
A delta is a landform made of sediment that builds up where a river meets a larger body of water, forming new land in a triangle or fan shape.
Mountain that erupts lava, rock, and gases.
Volcano
Raised area of land, smaller than a mountain.
Hill
Breaking down of rocks by natural forces.
Weathering
Restoring land after mining or damage.
Reclamation
How do tectonic plates affect the Earth’s surface?
Tectonic plates affect the Earth’s surface by moving and causing earthquakes, volcanoes, and the formation of mountains.
Flat or gently rolling land, often used for farming.
Plain
Dry region with little rainfall and sparse vegetation.
Desert
Dropping of sediment in new areas.
Deposition
Give one example of a natural process that changes landforms.
Erosion is a natural process that changes landforms by wearing away rocks and soil.
Flat elevated land that rises above nearby areas.
Plateau
Land surrounded by water.
Island
Movement of Earth’s plates forming mountains or quakes.
Tectonic Activity
Provide an example of a human process that changes the landform?
Building dams is a human process that changes landforms by flooding areas and creating reservoirs.
Low area between hills or mountains, often with a river.
Valley
Slow-moving river of ice that shapes landforms.
Glacier
DOUBLE: 1. Eruption forming new land 2. Movement of ice shaping valleys.
1. Volcanic Activity 2. Glaciation
What is the difference between erosion and weathering?
Weathering is the breaking down of rocks into smaller pieces by wind, water, ice, or chemicals, while erosion is the movement of those rock pieces from one place to another by wind, water, ice, or gravity.
