Changes to Earth

Slow and Rapid Changes

TermDefinition
Landslide When this occurs, Earth materials, like rock, sand, and soil, on the side of a slope or cliff drop down to a lower location. Water soaking into the ground often makes this happen.
Volcanic Eruption When this occurs, Earth material called lava comes out of the volcano flows down the side of the volcanic mountain (or is sent up into the air and lands nearby) where it hardens.
Flood When this occurs, a lot of water causes rivers and streams to overflow their banks over the surrounding land around them. Heavy rainfall in the area is usually the cause of this.
Earthquake When this occurs, the surface of the ground shakes and rolls causing damage to the Earth’s surface, like cracks and other openings, and damage to roads and buildings.
Weathering When this occurs, Earth materials, for example rocks are being broken apart. Little or big cracks in the rock are evidence that this is taking place.
Erosion When this occurs, Earth materials, like rock, sand, and soil, are being carried away from their original location. Water and wind are often the causes for this.
Deposition When this occurs, Earth materials that have been eroded are put in a new location. When the wind stops blowing, sand and soil may be put down in piles as large as dunes. Water may deposit its material at the end of a river and form a delta.
