Changes In Earth's surface
Tornadoes
This map shows where tornadoes mostly hit.
|
A tornado is formed when a funnel cloud touches the ground.Then the wind causes the tornado to spin.There are high winds during a tornado.Tornadoes damage houses,cars,
buildings,and other things.A tornado rates 1-5 which is is called the EF tornado scale.They rate a tornado by estimated wind speeds.Texas gets the most tornadoes each year.Texas gets about 125.Oklahoma comes next with 57 tornadoes and Kansas and Florida following close behind with 55 each year. |
Hurricanes
A hurricane is a tropical storm caused by the warm weather.The water evaporates more than any other time of the year.This causes more rain and sometimes very high wind speeds.The eye of a tornado is the calmest part.For more information on tornadoes click here.
Glacier
A glacier is a large piece of snow and ice.A glacier is formed when more sow falls in the winter than it melts in the summer.A glacier can form a glacial or hanging valley.A glacier carves away the stone and land beneath it.Glaciers move very slowly.
Landslides
A landslide and a mudslide is basically the same.A landslide is formed when movement people and animals or by tectonic plates.The movement shakes the land and causes some of it to fall like a avalanche.Mudslides are the same.Normally a landslide happens on a steep surface like a mountain or hill.
Tsunamis
A tsunami causes great damage to the Earth.A tsunami is formed in many different ways:
1.A earthquake could cause a tsunami
2.A landslide might fall into the ocean
3.A underwater volcano could erupt and cause a tsunami.

Volcanoes
A volcano is formed when magma works its way up from the upper mantle and it reaches the surface.Then when it reaches the surface the lava erupts.Over time the volcano will erupt and it will grow bigger Because of the igneous rock.There are many types of volcanoes to.
Earthquakes
A earthquake is formed when the tectonic plates move and break away.A fault is a break in the Earth's surface caused by the movement of the tectonic plates.A seismic waves are vibrations along faults.A seismic wave is the result of a earthquake.Earthquakes cause great damage if it is just right.
