Wind Erosion
Background Information: Wind is caused by changes in pressure and temperature in the Earth’s atmosphere. Wind erosion occurs when rocks and sediments are picked up and moved to another place by ice, water, wind, or gravity. Wind weathering usually occurs during the rainfall. Due to the temperature changes of the sea caused by the sun, the temperature of the surface rises, and the land heats the air above it. This heat causes wind to move faster in different directions.
Purpose: The purpose of the lab is to demonstrate the relationship between particle size and distance of movement caused by wind.
Hypothesis: If the particle increases then the distance will decrease because the …show more content…
The hypothesis was determining the distance of how far the substance traveled when different sized particles were tested. As the particle size grew, the measuring distance decreased. The data that was collected shows that the rocks didn’t move at any speed due to its heavy weight. As well as the sand, it moved 126 cm during trial 1, and 176 cm during trial 2.
Conclusion
Some errors that were found during our lab was that the fan was at different angles when certain substances were being tested. This impacted the lab in many different ways that data numbers were all over the place. If the fan was placed all in the same place for all the substances, the results would’ve been slightly different. The fan should have been set the same position and at normal speed. The main idea of the lab that was tested, was to show that wind picks up different substances and takes some farther than others. It’s good to know about why people study wind erosion because wind isn’t always the same speed. For example, if someone was building something near the ocean it wouldn’t be done fast due to the speed of the wind. Wind always seems to be faster near the
