Landslide
The breakdown of rock into smaller pieces from exposure to wind, water, or biological forces.
Weathering
any weathering that's caused by the activities of living organisms.
Biological Weathering
A huge spinning storm that forms over warm ocean water; with strong winds and heavy rains.
Hurricane
Tornado
Process by which weathered rock and soil are moved from one place to another.
Erosion
Process when rocks break down chemically, caused by acids and oxygen
Chemical Weathering
A destructive, rotating column of air that has very high wind speeds and that may be visible as a funnel-shaped cloud
Tornado
Weathering, erosion, deposition and cementation.
_________change
Gradual Change
Process in which sediment is laid down in new locations after being eroded away.
Deposition
Blows silt against exposed rock, which wears away the rock's surface.
Wind weathering
Shaking and vibration at the surface of the lithosphere (top layer or the crust) caused by movement along a fault line of tectonic plates. Scientists use a seismograph to detect the strength.
Earthquake
deltas, canyons, & flood plains
Erosion Landforms
Changes to Earth that take place in an ecosystem over a short period of time, from moments to weeks.
Catastrophic change
breaking down of rock by water in streams, rivers, oceans, rain or ice.
Water weathering
the sliding down of a mass of earth or rock from a mountain or cliff
Landside
This event __________________katrina was one of the worst natural disasters to hit the United States.
Hurricane
A slow change to Earth that occurs over a long period of time.
Gradual change
Weathering as ice and rock interact. They leave unique "U" shape marks on Earths crust.
Glacial weathering
Earthquake that occurs under ocean may cause......
Tsunami
