Weathering and Erosion

Weathering Weathering - the process that breaks down rocks into smaller pieces

The 3 types of weathering Physical Weathering (mechanical) Chemical Weathering Biological Weathering

Weathering Physical Weathering (mechanical) - is weathering that is caused by a physical force. This can be caused by water, ice, and wind. Water Ice Wind

Weathering Chemical Weathering - Occurs when there is a chemical reaction between water, air, or another substance and the material in rocks. This can be caused by water and air. Air Water

Weathering Biological Weathering - Weathering (physical or chemical) that is caused by living things. Lichens & Moss Animals Tress and Plants

Erosion Erosion _ the movement of weathered rock material from once place to another Erosion can be fast process or a slow one that occurs over thousands of years

Erosion can be caused by… Glaciers (Ice) Running Water Waves Wind Gravity

Erosion Glaciers (Ice) – A slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near poles. Glaciers move downhill and because their massive size and power they can carve away big chunks of land Glaciers can cause significant DAMEGE!

Erosion Glaciers (Ice) As you can see glaciers can carve away land

Erosion Running Water – As water flows over land it can remove rocks as well as to carve huge chunks of land

Erosion Waves – When waves hits rocks because of the strength and power they have they can break rocks or move rocks. it can cause erosion

Erosion Waves

Erosion Wind – Wind carry's away sediment from one place to another (long distances) When winds stops going fast is when the sediment goes back to the ground

Erosion Wind

Erosion Gravity – Can cause large chucks of land to fall downhill

Erosion

Deposition – The settling of eroded rock material on Earth’s surface

How do they work together to affect rocks? This two work together because at the beginning its a big normal rock then water, ice, wind, and temperature hit the rock and that process makes it brake down into smaller pieces. Days, weeks months, or even year go on a then glaciers, running water, waves wind, and gravity hit the smaller pieces of rock and moves them from one place to another.
