The hill near the playground has been changing over the last few months. During heavy rain, the dirt is being quickly washed off the hill. This is a problem for the class because the students are unable to play in this area since it is unstable and unsafe.
Which solution would be best to prevent the wind and water from changing the hill?

The best option to prevent the hill from continuing to be eroded is to plant new grass. The roots of the grass will absorb water and hold the dirt in place. As wind and rain wear things down and move them away, humans must come up with solutions to prevent it from getting worse. The other answers are not reasonable or will not work. Leaves will not absorb the water and will wash away, leaving it alone will allow the problem to get worse, and putting a slide on the hill is dangerous!

Our land is changed when wind and water break down the soil and wash it away. Hurricanes in the South cause a lot of damage and change the area in very severe ways. Below is a picture of the damage from Hurricane Katrina in New Orleans.
What could the city do to prevent the water from changing the shape of the land and damaging the buildings in the future?

The damage from Hurricane Katrina permanently changed the area and the land of New Orleans. The floodwaters destroyed many buildings, and when the water receded to the ocean, it dragged dirt, rocks, and debris along with it changing the landscape. The city could install barriers or levees to block the water from passing into the city. There were already some in place, but there could be taller levees installed or more of them.

Many times farmers face strong winds, and they can damage crops and change the shape of the land. Below you will see an image of a wheat field on a sunny day and then after a dust storm.
Farmers will often plant tall plants and shrubs alongside their wheat. Why would these plants help prevent the wind from changing the landscape and damaging crops?

Shrubs and tall plants next to fields of wheat, corn, and other crops help act as a windbreak and stop the wind and dust from tearing up the fields. If the soil is very dry, it will get swept up by the strong winds and create a tornado-like force that will bury all of the crops in dust and dirt. The shrubs block the soil from being picked up, and the wind from pushing through the crops the farmers are growing.

This beautiful canyon was formed by years and years of wind and water pushing through the ground and blowing against the sides. Erosion is the movement of broken down Earth to new places, and that is what the river and wind in this area have done. The water races through the canyon, cutting a path while the wind blows tiny particles of soil and sand into the walls breaking it away slowly and moving it to new places. Many times humans get involved and try to prevent wind and water from damaging areas.

The soil around Maddie's farm is becoming very dry and loose. When the wind blows many pieces are picked up and blown around her fields. This process is called desertification. The area is turning into a desert because of the wind and dry soil.

This is a widespread problem on many farms, especially in the mid-West, where it is very dry and can get windy. The best option to prevent the wind and water from changing the land's shape and damaging her farm is to water the soil to keep it wet and less dusty, plant tall shrubs to help block the wind, and rotate the crops, so the nutrients in the ground are not all used up. If farms are left to become very arid and dusty, it can create large dust storms and damage property and change the land over many miles.

The best and most reasonable way to stop wind or water for changing the shape of the land would be to plant shrubs and trees to hold the soil together. Tree roots stabilize and secure the soil helping it from being eroded. This process can help control erosion (the movement of broken-down materials), so there are fewer changes to the Earth.

Our land is changed when wind and water break down the soil and wash it away. Hurricanes and flooding cause damage when rocks, dirt, and sediment are carried away.
A city wants to prevent flooding of this level during the next storm. Which answer choice would NOT be a good way to prevent the land from being changed?

Floodwaters rush into the city and destroy homes, roads, and tear up plants. It would NOT be a good idea to place large umbrellas near the sides of the town to block the rain to stop the land from changing. This would not prevent a flood or keep erosion from taking place.

Beach erosion is widespread and changes the shape of the land forever. The most reasonable and practical way to slow the wind and water would be to bring in sand and plants to rebuild the beach; this will add more shoreline and help to strengthen the coast. This should help slow some of the erosion and stop the land from changing.

These aerial photos allow scientists to make comparisons of the same area over time to look for changes or similarities. In these photos, scientists could see that the shoreline has changed over the years. There is a reduction in the land visible, and more of it is underwater. The coastline has receded and become more narrow.

Erosion is the changing of the land's shape due to the movement of weathered bits of earth to another place. When wind and water pick up bits of rocks, dirt, and debris from the ground, they bring them to new locations. This movement changes the shape of the land and creates new landforms.

Beach erosion is widespread and changes the shape of the land forever. The most reasonable and practical way to slow the wind and water would be to bring in sand to rebuild the beach; this will add more shoreline and help to strengthen the coast. Then they can build barriers in the water to help break some of the waves before they reach the shore, so there isn't as much force pounding into the rocks and sand. This should help slow some of the erosion and stop the land from changing.

This classroom investigation is very much like the real process of erosion that happens in the natural world. The students' production that the "wind" will blow the sand everywhere is correct. The best option to prevent the changing of the landform is to build a wall in front of the hill. Building the wall behind it still leaves the hill exposed and will not help. Also, making a river will not stop the "wind" from blowing, so it is not a good option. A wall would be secure and take the gust of wind instead of the hill, thus saving it from breaking apart.

Many towns face a similar problem to this because moving water is so strong. The force of the water can cause the riverbanks to change shape, which can be dangerous if there are buildings or homes constructed right along the river. The best option would be to build a dam upstream that would stop the water flow downstream. The town could control how much water passes through the dam so that the damage can be limited. This solution could slow the erosion and stop the changing of the land's shape.

London's simple example of eating a lollipop is very much like wind and water, changing the shape of the land. As waves crash into the shore of a beach, they move sand away and expose rocks that change the way the area looks. Rivers often rush through canyons carving the sides into new shapes and sights. Licking the lollipop is wearing it down and changing the shape.

The best and most reasonable choice for slowing wind and water from changing the shape of the land would be to bring in new sand or dirt to fill in areas that have started to wear away. Erosion is the movement of materials that have been broken down, so bringing in new sand or dirt can help slow the water and wind from changing the landform.

All of these listed answer choices are correct. Wind, water, and plants all change the shape of the land through weathering and erosion. When the land changes, it can cause problems for humans and the environment. Sometimes humans have to intervene and help fix what nature has created.

Erosion is widespread and changes the shape of the land forever. The most reasonable and practical way to slow the wind and water would be to add more trees and plants along the bank. The additional trees and plants will help stabilize the soil and keep it from sliding and moving. This should help slow some of the erosion and stop the land from changing.

Weathering is the process of wind, water, and vegetation breaking apart rocks and other natural materials. The house in the example is unstable because the rocks below the foundation have been beaten by rain and wind and broken apart.
