5th Grade Science-Reshaping Earths Surface
Transcript of 5th Grade Science-Reshaping Earths Surface
Students will understand that volcanoes, earthquakes, uplift, weathering, and erosion reshape Earth's surface. The Earth in Constant Change The Earth’s surface is constantly changing. Some changes happen very slowly over long periods of time, such as weathering, erosion, and uplift. Other changes happen suddenly such as landslides, volcanic eruptions, and earthquakes. All around us, we can see the effects of the building up and breaking down of the Earth’s surface (USOE. 2002). Weathering and Erosion What is Weathering?
-Weathering is the breaking up of surfaces by forces such as the air and water of the atmosphere (edu.pe.ca. (n.d.)). Video on Weathering and Erosion Volcanoes: Create new islands and land.
Provide habitat to pioneer species.
Create economic mineral deposits.
Create beautiful landscapes (Bates 1969).
Earthquakes: Create new faults. When plate tectonics shift, they can create mountains, valleys, volcanoes and much more, reshaping earths surface.
Uplift: The vertical rising of the earths surface in response to natural causes, ie: volcanoes, earthquakes, etc. The land is literally lifted up.
Landslides: The sliding down of a mass, or a huge chunk of earth or rock from a mountain or cliff. Usually caused by heavy rain and unstable slopes. Work Cited Bates, R. (1969).Volcano World. Retrieved from http://volcano.oregonstate.edu/what-are-some-good-things-volcanoes-do

-Erosion is the process by which the surface of the Earth gets worn down. Erosion can be caused by natural elements such as wind and glacial ice (Scholastic. 2008, 12 11). Other Processes
