• erosion

• deposition

• jackhammering

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

• mechanical weathering
• chemical weathering
• erosion weathering
• deposition

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of:

• frost wedging

• acid rain

• permeability

• abrasion

Weeds growing into the cracks in a sidewalk and the sidewalk begins to crumble is an example of:

• mechanical weathering
• chemical weathering

A creep is

• a slow, gradual movement of earth

• a quick movement of earth that behaves like a fluid

• a quick movement of rocks

• a slow, gradual movement of water

Mechanical weathering happens when

• a substance is broken down but not changed

• a substance is transformed into a new substance

• a substance is covered by water

• a substance is transformed by natural means

A soil's texture is determined by its

• water content

• mineral composition

• thickness

• particle sizes
