4th Grade Science › Measure effects of weathering on rate of erosion
Scientists are studying different cliff faces and how their rates of erosion are affected by the slope of the rock formation. Meredith wants to come up with a way to extend the amount of time that it takes for a cliff face to be completely eroded. What can Meridith recommend doing after reviewing the relationship between slope and erosion rate in the table below?
The data table below shows the width of the beach measured every two years.
What natural process is likely causing the beach to become shorter in width each year?
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?
The data table below shows the width of the beach measured every two years.
Based on the pattern, what will the width of the beach most likely be in year 11?
True or False: The effects of weathering on the rate of erosion cannot be measured.
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?
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 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.
What does this data tell you about moving water versus standing water and how it changes the landscape over time?
Which example is NOT a direct cause of erosion?
What is the best scientific method for determining if erosion is taking place?

Does this process take a long time and how does your data show you the evidence?
