Weather and Erosion Rate - 4th Grade Science
Card 1 of 80
Steven and his sister Sasha are making observations about erosion and the rate of movement of materials. They are looking at different bodies of water and how small rocks are being moved. Sasha took a piece of broken rock about 2 cm and threw it into each body of water to observe what happened. They followed the material if it moved to get a distance of travel. They recorded the data below.

Sasha and Steven are making observations about how different bodies of water move eroded materials. Rivers are a fast-moving flow of water, lakes and ponds are primarily standing water, and streams are slow-moving bodies of water. Based on the data, they measured and observed the river moved the materials the farthest distance. A connection can be made about the rate of running water and how materials will be eroded or carried away. The faster a body of water moves, the further and faster sediment and eroded materials will move.

Weathering and erosion are usually two terms used simultaneously and together, but each has its independent definition and usage. Weathering used in this context means the wearing away or changing the appearance and texture of something that is being worn away and broken down by the wind, water, ice, and vegetation. Water seeps into the rocks and freezes time after time, which slowly breaks the rock into pieces, plant roots grow through cliffsides and rocks, and the wind and rain batter shorelines with tiny fragments of sediments and water drops. All of these actions slowly break the rocks, shorelines, and cliff faces down.

Weathering and erosion are usually heard used together, but each has its definition and essential part of shaping our landscapes over time. Erosion is the process by which the surface of the earth is worn away and moved by the action of water, vegetation, winds, and ice. As fragments of rock or debris are broken off through the process of weathering, the materials are moved and worn away by erosion. A river will carry sediment downstream and move it to new locations as the process of weathering continues.

What type of erosion would occur most frequently in the Mohave Desert?
What type of erosion would occur most frequently in the Mohave Desert?
Tap to reveal answer
The type of erosion most likely to occur in the Mohave Desert would be wind erosion. The desert would not experience glacial erosion because there are no frozen blocks of ice. In the desert, there is limited water and vegetation, so neither of those would be likely to cause erosion. The desert does experience high winds and sandstorms, which would cause movement of the materials and sediment in the area.

Erosion is the movement of materials and broken down debris from the process of weathering. The correct answer choice must address the movement of materials, not just the breaking down of materials. "Wind blowing away sediment" is the right answer because it demonstrates the movement of sediment by the wind; sediment is material that settles in water or on shorelines, so this is a reasonable type of debris that would be picked up and moved.

Rivers are a fast-moving flow of water, lakes, and ponds are primarily standing water, and streams are slow-moving bodies of water. Based on the data, they measured and observed the river moved the materials the farthest distance. A connection can be made about the rate of running water and how materials will be eroded or carried away. The faster a body of water moves, the further and faster sediment and eroded materials will move.

Miranda's class was investigating how weathering affected the rate of erosion. They put chunks of bar soap in an aluminum foil tray and filled it about halfway with water. They measured the soap after soaking for about three hours and then sprayed the bar of soap with a squeeze bottle full of water. They observed bits of soap breaking off and floating in the water. They took final measurements and recorded them in the data chart below.
Based on this data, what had the most significant effect on the soap?

This observation is focused on the effect that weathering has on the rate of erosion. As wind and water break bits of material off, that material is moved to a new location. When looking at the data, there was a 45cm3 difference between the bar of soap at the beginning of the investigation and the end of soaking. When they measured the soap after spraying, it only had a volume of 2cm3, which was a decrease of 78cm3. Using the data from the observations, it can be concluded that spraying the soap has a more significant impact on its size and volume.

They soaked the soap for about three hours and then sprayed the bar of soap with a squeeze bottle full of water. Miranda noticed that when the soap was sitting in the water it was getting smaller but took a very long time. There was barely a change after the three hours. When they sprayed the bars of soap they broke down quickly and bits of soap began breaking off. They repeated the experiment with multiple bars of soap and saw the same results.
Does this process take a long time and how does your data show you the evidence?

The natural process of weathering and erosion happens very slowly, and this investigation was no different. After Miranda's class has placed the soap into the standing water, they waited three hours and barely saw a difference in the size and volume. There was only a 45cm3 difference in the volume after three hours. It was not until moving water by way of the spray bottles did things speed up. Had Miranda's class just left the soap to be eroded, it could have taken more than one school day to complete the process.

Over time the wind, ice, vegetation, and water wear away small bits and pieces of sediment, rock, and other natural materials. Erosion takes these bits of material and moves them to a new location. When reviewing the observations and data from Miranda's investigation, one may notice that running water (the spray bottle) eroded more material in a shorter period. When comparing moving water and standing water, there is a significant difference, and running water would change the landscape more quickly.

Scientists are studying different cliff faces and how their rates of erosion are affected by the slope of the rock formation. DJ thinks that the steeper the cliff, the higher or faster the rate of erosion will be. Matt says it will be the opposite, that the steeper the cliff is, the lower or slower the rate of erosion will be. They know gravity pulls rocks down, and this will have an effect on the cliff's erosion rate. Based on the data chart below, who is correct, and why?

DJ and Matt are both on the right track when they are thinking about rocks being pulled down and affected by gravity, but that is where the commonalities stop. DJ is correct in his thinking related to the steep rock cliffs. The steeper the cliff is, the sooner and faster it will be eroded. The steep slope allows the force of gravity to move more rock more quickly. When looking at the data, a trend can be seen, the higher the slope of the cliffside is, the sooner it will erode. A cliffside with a 30o slope will erode in 61 years compared to an 87o slope eroding in 24 years.

Meredith can use this data table to look for a pattern or connection between the slope of the cliffside and the average erosion rate. Based on the measurements recorded, the lower the slope, the longer it takes for the cliff to erode. Meredith could suggest building the cliffside up to reduce the slope so that scientists could increase the amount of time it would take to erode. The steep slope allows the force of gravity to move more rock faster, so by reducing the slope, the rock will not move as quickly.

The natural process of weathering and erosion happens very slowly. Over time the wind, ice, vegetation, and water wear away small bits and pieces of sediment, rock, and other natural materials. Erosion takes these bits of material and moves them to a new location. In this example, erosion due to the ocean waves crashing onto the beach is washing away sand, causing it to be slowly moved out to sea, and the beach becomes shorter in width.
