NCFE Review #2 Lithosphere Part I: Rocks, Soil, Weathering/Eros

How does freezing water cause the weathering of rocks?  The freezing water—

• keeps the rocks in place
• makes the rocks last longer
• expands cracks and breaks rocks
• causes rocks to fall in landslides

The process that breaks down rocks and other materials on Earth's surface is called

• weathering
• erosion
• soil conservation
• decomposition

How does wind abrasion work?

• Sediment is blown off a surface from wind.
• Wind-blown sediment strikes a surface.
• Wind blows large chunks of rock off a surface.
• Sediment falls off of a surface on its own.

What is mechanical weathering?

• Process through which rocks are physically broken into smaller pieces.
• Rocks are broken down through chemical changes.
• Rocks are worn away from acid in plant roots.
• Rocks broken down by machinery.
