Explain Earth's Rotation and Revolution
-What is it?
-How long does it take?
-What does it cause?
Rotation: Spinning on its axis. Takes the Earth 24 hours/1 day. Causes Day & Night Cycle and Shadows.
Revolution: To orbit or go around. Take the Earth 365 days/ 1 year to orbit around the Sun. Tilt of the Earth causes the Season.

Which of these are most likely formed by the process shown?
A. Glaciers
B. Mountains
C. Sand dunes
D. Sedimentary Rocks

In the Carbon-Oxygen Cycle, what do plants release from their leaves that we absorb and what do we release that plants take in?
Plants release oxygen and we release carbon dioxide
Objects that blow into a swimming pool or that are dropped into the pool by swimmers need to be removed. These objects include foam cups, keys, and coins. What is a useful method for removing the foam cups?

Baby Camdyn is playing with a cup of water with a straw in it. When she sticks her hand in the cup to grab the straw, she isn't able to get it because it appears broken. Why is it that she is struggling to grab the straw that is in the cup.
Refraction. Light is bending or slowing down when it hits the water causing the straw to appear broken or bent.
What are the processes that happen to a rock? Explain each one.
Hint: Wind, Water, Ice & Gravity cause this to happen
