Weathering, Erosion, deposition

8th Grade Science

Last week, we learned

earth Systems

• The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to the lush rainforests and high mountaintops.

• Envelope of gas that keeps the planet warm
• Provides oxygen and carbon dioxide

• Areas of Earth that are covered with enormous amounts of liquid water

• Solid portion of the Earth
• Earth's rocks, minerals, soil, sediment

• Contains huge quantities of ice (mostly found at the poles)

Recall:

How do these spheres interact with each other?

Today, I will be able to:

Explain the difference between weathering, erosion, and deposition

Identify the agents that drive geoscience processes

Weathering

Weathering

The breaking down of rocks and sediment

Chemical

erosion

erosion

The movement of rocks and sediment

Deposition

Deposition

The dropping of rocks and sediment in a new place

your turn!

Take 5 MINUTES to sketch an example in your trifold, then share with your group.
