Wind Weathering

Background:

Wind weathering is mostly found in a flat, bare, and dry area. It picks up soil, dust, and sand and carries them away as well as breaks them down into smaller and smaller pieces, for example, rocks. The wind erosion usually happens in the summer, spring, and fall. Mechanical Weathering is a physical breakdown of rocks into smaller and smaller pieces. In the picture below, the rock formation is caused from mechanical weathering, the pieces are exactly the same as the whole except smaller. In image 1, it shows a rock being weathered away with the wind, little by little, becoming smaller with the same shape. In Image 2, it shows when the wind hits, the lighter substances goes farther and higher. As the bigger ones roll on the ground. …show more content…
Hypothesis: If the particle size increases then the distance will move and will decrease because the wind can take smaller particles into larger distances and can’t move rocks since they have a bigger mass.

Procedure:
Label start point, where the soil and small particle materials are going to be, and set fan behind start point.
Place the measuring tape on the side of the lab to measure the distance that the small particles travel.
Place soil and small particles at start point and set fan at normal speed.
Calculate the distance each particle traveled in centimeters.
Repeat steps 3 and 4, and gather data for Trial 1 and Trial 2.
Place rocks at start point and set fan at normal speed.
Calculate the distance that rocks travel in centimeters.
Repeat steps 6 and 7, and gather data for Trial 1 and Trial 2.

Materials:
3 speed fan
Soil (35mL)
Sand (35mL)
Rocks (35mL)
Measuring tape

Science Report Abrasion Essay

Abrasion Science Report Purpose: What effect does the length of time of abrasion have on the way rock particles weather? Rocks are constantly changing their size because of the weathering process. Weathering is when rocks are broken down by physical or chemical means. An example of physical weathering is abrasion. Wind, water, and gravity can cause abrasion to happen. For example, in a stream, the current pushes rocks forward, causing them to hit and rub against other rocks. This causes the rocks…
