A lab experiment designed to observe and record the effects of weathering on sand and pebbles using wind, water, and chemical reactions. Students will build sand mountains, simulate rain, and create a chemical weathering chamber to study the differences between weathering and erosion.

Name _____________________________________ Date _______
The atmosphere of our planet is constantly changing the surface of the Earth. Rocks
are continually weathered down by wind, water, chemicals, and ice. After the rocks are broken down into smaller pieces we call sediment, they are eroded away and deposited
in lake beds and on the ocean floor. Wind erosion is the process by which wind moves
sand or soil from one location to another. Wind erosion changes the environment,
especially if there is nothing to block its effects. Water erosion is the process by which
water moves sand or soil from one location to another. Water erosion may change the
environment, especially if there is nothing to support the sand or soil. Chemical
weathering is the process by which chemicals in water wear away the surface of the earth by reacting with rocks and minerals.
Weathering : The process by which water, wind, and ice wear down rocks and other
exposed surfaces.
Erosion : The movement of weathered rock by wind, water, ice, or gravity.
