  In this lesson I learned all about erosion and earth. There is a slow process and a fast process of how erosion affects the earth. For example, the fast process would be tornadoes, volcanoes, earthquakes tsunamis. Because those natural disasters immediately change the environment in just a few moments. The slow process is like fast moving rivers, waterfalls and lakes. They slowly chip away at the rocks by smoothing them out and  shapes the land around them. 

as you see in this picture is was effected by wind

We also learned about wind erosion. Wind erosion by itself does not do much damage but if you get wind erosion and sand  together they chip away on objects and makes their shapes smoother.

1. ‎Astronomy: who studies stars, planets, moons, comets and galaxies, as well as many other celestial objects either in Observational astronomy, in analyzing the data or in theoretical astronomy.

    2. geographers: are historically known as people who make maps, map making is actually the field         of study of cartography(greek word map).

   3. physicist: is a scientist trained to understand the interactions of matter and energy across the                physical universe.

Rapid vs Slow process

Rapid process vs Slow process

Rapid process: volcanos, earthquakes, landslide, tornado, title-wave, fire, cyclone and flash flood

Slow process: wind, stream,

Wind Erosion

Wind Erosion

Wind Erosion is caused when hot wind goes up and air comes to take its

place

Q: what effect will the freeze-thaw cycle have on our rock?

Method : step 1: make it in a ball 

               step 2 :mix water

               step 3 :put it in freezer

observations: it's outside was slimy and soft

"Wadi field Trip"

Wadi field Trip

As Mrs. McGrath said ,we walked into the Wadi not as 5th grade students, but as Earth scientist.I could not believe the Wadi as Dr.Bill said this was once where a big river was. I looked  around all I could see was a big dusty Crevice in the ground and I was in it. Dr.Bill also said that megalodons and basilosaurus lived in this biome. I could not picture a megalodon and basilosaurus swimming above me.

Experiment #1

Experiment 1

1. what happens when water flows over the earth materials?

     2.Will water affect the soil as it flows?

develop a hypothesis : I think the water will change the shape of the soil and the soil will harden

observation:At the start I saw that the water was making a small pool under the bucket then I saw that the water was making a split crevice in the ground from the pool down hill.

     In all I think that water is strong force some times and can be slow and I think that water is amazing...stay........tune.....experiment..1..part..2...is...coming...up...next...on...Prescott's...Science...blog
