Erosion, Weathering, LAND FORMS and bodies of water

EROSION

• After weathering, erosion carry's away the leftovers  of the rocks 

mechanical Weathering

• Mechanical Weathering does not change the chemical structure.
• Types include: Crystal growth, Plant roots, Lightning and Expanding ice
• Plant roots grow and push apart the rocks
•  Ice freezes in cracks of rocks and expands,  breaking it apart into peices
• Mechanical Weathering usually happens close to the Earths surface.

Chemical Weathering

• Chemical Weathering does change the chemical structure.
• When water mixes with carbon dioxide in the air it makes carbonic acid.  
• The carbonic acid reacts with calcite in limestone  to where it away.

landforms

• Mountains are tall hills with pointed tops.
• They have steep sides.
• They are formed when tectonic plates converge.
• They also can be formed when volcanoes erupt and build masses of land.  

a cape

• A cape is a stretch of land made by a volcanic eruption.  
• A cape used  to be a part of a major piece of land.
• Weathering later wears at it and makes it thinner and thinner over time.
