The tallest of Earth’s landforms. Have steep slopes and peaks. Can be single or in chain. | Mountains |
Smaller than mountains. Rise above the land around them and have rounded crests. | Hills |
Long, narrow regions of land between mountain ranges or hills | Valleys |
Deep valleys with steep sides. Often have a river that runs along the bottom. | Canyons |
High landforms with fairly flat tops. | Plateau |
Like a plateau but smaller | Mesa |
The floor of a river valley on either side of the river | Flood Plain |
Landforms found on or near a coastline. Ex. beaches, marshlands, and coastal plains | Coastal Landforms |
Ocean landform that forms the edges of a continent. Slopes gradually from sea level. | Continental Shelf |
Where the continental shelf drops steeply to the ocean floor | Continental Slope |
Deep canyon found on the ocean floor | Trench |
A mountain chain that runs through the world ocean | Mid-Ocean Ridge |
Huge, steep sided mountains that rise from the ocean floor | Seamounts |
Shows the shape of landforms and their height above sea level | Topographic Map |
Connects points on a topographic map that have the same elevation (height) | Countour Lines |
The breaking of larger rocks into smaller pieces due to wind, water, ice, and plant roots | Mechanical Weathering |
Small pieces of rock formed by weathering | Sediment |
The changing of rock into other materials caused by small amounts of acid carried by rain water | Chemical Weathering |
The carrying away of water caused by water, wind, or moving ice | Erosion |
The dropping, or releasing, of sediments that have been moved from one place to another | Deposition |
When a river moves across a wide flat region the river begins to wind in smooth curves | Meanders |
Melted rock below the Earth's surface | Magma |
Magma that has made its way to the Earth's surface | Lava |
Rock material deposited by a glacier | Glacial Deposit |
