Weathering

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

• 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.

During chemical weathering, what can happen to the type of rock that has undergone chemical weathering?

• a new rock is produced that is larger than the original rock
• a new rock is produced that is the same as the original rock
• a new rock is produced that is different from the original rock 
• no new rock is created - it is just smaller in size

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.

How do plants weather rocks?

• during photosynthesis
• when roots grow into cracks of rocks and expand the rock
• when the plant moves water from the roots to the leaves
