EROSION
by Austin
Erosion is when water, wind, and plants eat away at the earth. Do you ever wonder why some rivers are really, really wide? Rivers get wider because their fast moving water makes the dirt on the sides of rivers fall into the river and it gets carried away downstream. Erosion happens almost everywhere, not just in rivers. So I bet if you go into the woods or maybe even in your back yard, you might find erosion.
Here are some examples of erosion that we found behind our school:
Crazy Roots
by Abigail
There is a tree growing on the playground next to the school. Its roots are growing very out of control. The roots are breaking out of the dirt and rather close to the school. I think that if there wasn’t a foundation, in many years, the roots could grow under the school. I predict that if the erosion continues, the plants around the tree will die because the roots will take the water and nutrients from the soil. I also think that the main erosion agent is gravity because , the erosion looks very weighed down. The eroded material is going down the hill, probably from rain, because it is pretty much following the dirt, which is the eroded material. A way to stop the erosion is to pack down some heavy dirt or concrete around it.
Showing Roots
by Liam
You can see the roots of the tree above the ground. I think the erosion happened because water and rocks washed away the dirt above and around the roots. I think the eroded material is going to the nearby river and then that material will get washed away. If the erosion continues then I think the roots will detach from the ground causing the tree to fall. I think a good way to stop the erosion would be to get more dirt and pack it down before the roots show.
The Roots
by Dylan
There are roots showing. The wind is causing dirt to go up in the air. If this keeps happening, the roots will get exposed and the tree will die. The roots are near a tree with the bench attached to it. This is a place were people walk. The wind blows dirt into the air and people trample on the roots which flicks the dirt away which causes erosion. Water carries the dirt away down into the river or other places. Gravity might also eroding it. The dirt gets stuck on the pole of the bench and on peoples shoes. Kids can pat dirt on the roots so the roots will be safe. That’s how we can stop it.

Saving a Tree
By Rian
There used to be sand on the roots and the sand got pushed away because people walked over it. Rain is pushing the sand down the hill. This is causing the erosion. If the erosion keeps happening the tree might die. If people stop walking on it the tree might live and the roots might go underground or the sand will go on it. Another way to stop the erosion is to put sand on it then not touch it.
Tree Roots
By Max
I think the picture of the tree we took is different than other trees because some of its roots are showing. A way that the erosion is happening is from people trampling on the roots. Another way that the erosion is happening is from water carrying it away to a river. A way to stop the erosion is to build a small wall around the tree roots.
Roots Showing
by Zachary
The tree that is growing is different than other trees. Its roots show. The roots are showing because wind is taking away the dirt, exposing the roots. If this keeps happening the roots will not be attached to the ground and the tree will die. The materials will be carried into the nearby river to be swept away by the water currant. To stop the erosion you could put a metal wall above the hill so it will prevent the water and rock from coming in and taking the dirt into the river. Another example of this type of erosion is when wind caries sand to make dunes for the sand on the dunes to be carried away making lots of dunes.
