The following is what your student needs to know by the end of September. Please contact me through parent-square if you have any questions or concerns. Thank You.
SS5E1. Obtain, evaluate, and communicate information to identify surface features on the Earth caused by constructive and/or destructive processes.
a. Construct an argument supported by scientific evidence to identify surface features (examples could include deltas, sand dunes, mountains, volcanoes) as being caused by constructive and/or destructive processes (examples could include deposition, weathering, erosion, and impact of organisms).
b. Develop simple interactive models to collect data that illustrate how changes in surface features are/were caused by constructive and/or destructive processes.
c. Ask questions to obtain information on how technology is used to limit and/or predict the impact of constructive and destructive processes. (Clarification statement: Examples could include seismological studies, flood forecasting (GIS maps), engineering/construction methods and materials, and infrared/satellite imagery.)
Weathering, Erosion and Deposition Cycle
Weathering, Erosion and Deposition Cycle
Weathering is when rocks and soil are worn down.
Erosion is when the material that is worn down is carried away by wind, water, living beings or gravity.
Deposition is when those materials stop moving and build up somewhere else.
What is a Delta and how is it formed?
When rain falls and snow melts the water flows downhill and forms a river. As the water is flowing it picks up small pieces of dirt and rock, which is known as sediment. This sediment is what makes rivers look brown. When a river gets close to the ocean the land flattens out and the river slows down. When the river slows down the sediment begins falling to the bottom of the river. Over time the sediment builds up and new land is formed, which forces the river to flow in a different direction. The river spreads out and begins flowing in many different directions forming a triangular type shape.
These sand dunes have moved over time and partially covered some ancient pyramid in Sudan. This photo was taken in 2007. If you were to go back today, the sand dunes would have moved again. Dunes are constantly moving. Check out this site on sand dunes to learn more.
The Power of Earthquakes
The Power of Earthquakes
Earthquakes can be both a constructive and destructive force. When the fault lines move they can cause incredible damage (destructive) and they also can cause new land formations (constructive). Mostly though, earthquakes cause destruction.
