We are going to have our Earth's Surface Science assessment on FRIDAY! This week I will be giving you homework that will help you with your assessment. I hope that you will take the time to REALLY understand and RESEARCH anything that you may not understand.
For tonight's assignment, you will answer 5 questions in Notability and then put them in your Drop Box folder. If you don't have your iPad, then answer the following questions on paper and turn them in tomorrow.
1. Look at these pictures of canyon floods and then answer the question below the pictures.
If you had to make a model of a canyon flood, which of the following choices would be the best way to demonstrate what the canyon would look like after a flood?
a) a tray of sand with water dripping through it
b) a tray of sand with water pouring through it
c) a tray of sand with a blow dryer set up near by
d) a tray of sand with some plants along the edges
Select your answer, and then EXPLAIN why that is your choice. Why do you think that is the answer? Hint: Think about when we went to Zion and made our canyons and poured water in them.
2. Look at the picture below, then explain how erosion causes river rocks to become smooth and rounded. Use Google and do some research if you need help, or

3. Which type of erosion moves the most rock on earth's surface? Need some help?

4. If I wanted to research what Utah was like 35 million years ago, what would my best source of information be?
a) Ask my teacher what Utah looked like 35 million years ago (certainly she is that old and would know!).
b) Ask my grandpa what Utah looked like 35 million years ago (maybe he is that old).
c) Do a Google search "35 million years ago".
d) Do a Google search "Utah, 35 million years ago".
Explain why your answer choice is correct.
5. U-shaped valleys in Northern Utah were created by glaciers. Glaciers are the type of erosion that causes U-shaped valleys to be formed. Look at the picture of the U-shaped valley below, how long do you think it takes a glacier to make a valley?

Glacial Valley |
a) less than a year
b) 10-20 years
c) a century or more
d) thousands of years
