You dig a small hole in the soil and the next day it rains. The hole fills with water, but does not empty even after several days of dry weather. What is the soil mostly made of?

Layers of soil are also known as:

• Soil Profiles
• Soil Horizons

These rocks were made smooth by wind blowing smaller rock particles across their surface.  This is an example of:

• ice wedging
• chemical weathering
• acid rain
• abrasion

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

• ice wedging
• acid rain
• permeability
• abrasion
