1 Weathering, Erosion, & Soil By: Daniel Cameron

2 What is erosion, weathering, & soil?  Erosion is a process that wears away Earth’s surfaces.  Weathering is the breaking down of Earth's rocks, soils and minerals.  Soil is a natural body of Earth formed from the particles of broken rock

3  It usually occurs due to transport by wind, water, or ice; by down-slope creep of soil and other material under the force of gravity. Erosion of Alaska’s Coast

4 Erosion  Erosion is a natural process, but it has been increased dramatically by human land use.

5 Hurricanes causing erosion

6  Two important classifications of weathering processes exist — physical and chemical weathering.

7 Weathering  Physical and chemical weathering includes the processes of...frost action...thermal expansion...wetting and drying...salt decay.

8  Soil is composed of particles of broken rock.

9 Soil  Soil differs from its parent rock due to interactions between the lithosphere, hydrosphere, atmosphere, and the biosphere.

10  1.What are the two types of weathering? http://www.geography4kids.com/files/land_weathering.html http://www.geography4kids.com/files/land_weathering.html  2.What are the four agents of erosion that wear away Earth’s surface? http://geography.about.com/od/physicalgeography/a/erosion.htm http://geography.about.com/od/physicalgeography/a/erosion.htm  3.Most soils have a density of what? http://en.wikipedia.org/wiki/Soil http://en.wikipedia.org/wiki/Soil  4.Erosion is defined as the removal of what? http://www.physicalgeography.net/fundamentals/10w.html http://www.physicalgeography.net/fundamentals/10w.html

11 Scavenger Hunt continued  5.Where does the energy of erosion come from? http://www.physicalgeography.net/fundamentals/10w.html http://www.physicalgeography.net/fundamentals/10w.html  6.Mineral Weathering that is driven by what? http://courses.soil.ncsu.edu/resources/soil_classification_g enesis/mineral_weathering/mineral_weathering.swf http://courses.soil.ncsu.edu/resources/soil_classification_g enesis/mineral_weathering/mineral_weathering.swf http://courses.soil.ncsu.edu/resources/soil_classification_g enesis/mineral_weathering/mineral_weathering.swf  7.Soil covers a major portion of what? http://42explore.com/dirt.htm http://42explore.com/dirt.htm  8.What is the difference between soil and dirt? http://school.discoveryeducation.com/schooladve ntures/soil/down_dirty.html

12 Scavenger Hunt continued  9.What kind of erosion formed the Grand Canyon? http://www.geography4kids.com/files/land_erosion.html http://www.geography4kids.com/files/land_erosion.html  10. The word erosion comes from what 2 words? http://www.watersheds.org/earth/erosion.htm http://www.watersheds.org/earth/erosion.htm
