Science
• SC.4.E.6.4 Describe the basic differences between physical weathering
(breaking down of rock by wind, water, ice, temperature change, and
plants) and erosion (movement of rock by gravity, wind, water, and ice).

What is Erosion?
• Erosion is the movement of sediments from one place to
another. Water is the primary agent of erosion, though wind
and glacier ice also contribute .
