Weathering, Erosion, & Deposition Content-Roberts F24

How can ice change the physical appearance of rocks?

• ice will mix with carbon dioxide and make it acidic but the rock will not change

• Ice can get into the cracks of rock freezing, expanding, and breaking the rock. This is what Mrs. Roberts calls Frost Wedging which is Mechanical/Physical weathering

• ice can mix with oxygen causing oxidation to happen. The rock will go through chemical weathering.

Which type of weathering is happening in the picture? Why?

• Mechanical Weathering. The rock is Frost Wedging because ice is changing its color.

• Chemical Weathering. Because the rock is going through Oxidation. The statue is mixing with Oxygen

• Astronomical Weathering. Because the statue is sad. Just sad!

Rust can happen to rocks that contain iron when they mix with Oxygen. Which type of Weathering is happening?

• chemical: oxidation

• mechanical:plant growth

• thermal expansion and contraction.

This is an example of ____________

• physical or mechanical

• chemical

• no weathering is happening

How do Sand Dunes form?

• Sand is moved by gravity and then eroded away.

• Sand is moved by water and eroded by wind.

• Sand is moved by wind and then deposition happens when its layed down.
