Geological processes change the earth´s surface over time by weathering, erosion, and deposition. Weathering is when parts of something is broken off. Erosion is when the parts of something that were broken from being moved. Deposition is when the stuff that was broken off is dropped somewhere else.

 One geological process was in the station: physical/mechanical weathering. in the station, the sugar cube was placed into a container that had sandpaper on the inside. When you shook the container with the sugar cube inside the edges of the cube weathered off and eventualy becomes a sphere. Another geological process was in the station: wave erosion station. When you took the sponge and made waves go into the sand on the side the water took the sand and flattened at a slant. this was an example of erosion. the final geological process was in the station: deposition station. we made an indent in the soil as a river and we poured water down the ¨river¨ and the water took soil off of the edges of the river and the soil ended at the bottom. this is an example of deposition.

 The evidence supports the claim because it backs up the weathering, erosion, and deposition by explaining how they make the geological processes. The twin sisters mountain (hill) trail has two pillars of rock they have been weathered by the wind and took that form. they will slowly get smaller over many years and will eventualy be nothing.

I infer that the hill trail twin sisters in Washington were formed by the geological processes erosion and glaciers.

the evidence that supports is in the station: soil erosion we poured water in the soil and when the water came out of the bottle of just soil, the water was darker. When the water came out of the bottle with soil and leaves, the water was a lot clearer than the one with just soil. when the water came through the bottle with grass growing in it, the water was almost clear. when the water came through the bottles every time the water brought some dirt. This is like how wind takes rocks and brushes them against something so the rocks break the bigger object only by a little though but breaks the rock at the same time. another way wind weathering objects is how wind takes loose objects off of something. more evidence that supports this inference is, according to www.atlasobscura.com it says “Science tells us that the Twin Sisters formation is the result of erosion sculpting the two spires between 12-15,000 years ago when the area was pounded by a massive flood.” This shows that the hill trail twin sisters Washington were made by erosion and glaciers.

1.water goes down too far for waves to hit but strong wind sill weathers it today.

2.Waves hit the rocks because of a massive flood in the Columbia River that was happening in the 4th picture but the water level got lower and lower.

waves ware down the crack in the center to make two pillars.
