Modeling Earth and Its Layers + Weathering

Constructive processes tear down features on Earth’s surface.

Destructive processes tear down features on Earth’s surface.

Land form is a combination of what?

Which type of weathering alters (change) the chemical composition of rock?

Which type of weathering is the breaking of rock into pieces, called sediment, without changing the chemical composition of the rock?

Which elements are cause of weathering?

All rocks are made up of the same mineral composition therefore all rock are less resistant to weathering.

The difference in weathering rate can produce unusual landforms.

Which is the removal of weathered material from one location to another?

Which elements are cause of erosion?

Erosion occurs at the same rates.

Which are factors that affect the rate of erosion?

After material has been eroded, a constructive process take place.

Sediment deposited in water will forms layers called ground.

Deposition is the laying down or settling of eroded material.

The crust under oceans is called what?

Earth’s mantle is the thick middle layer in the solid part of Earth, immediately below the crust.

The dense metallic center of Earth is the outer core.

Outer core is made up of mostly iron with small amounts of nickel and other elements that are liquid form.

Scientist learned that the outer core is liquid by analyzing earthquake waves.
