REVIEW!!!
What is climate?
general pattern of weather in an area over a long period of time [30 years or more (many decades)]
Why does the sun appear to be moving?
Earth's Rotation
REVIEW!!!
What is a closed circuit?

REVIEW!!!
What is refraction?
the bending of light as it moves through one medium into another
What is the sun mostly composed of?
Gases-Hydrogen and Helium
How many 'Earths' can fit in the Sun?
1,300,000!

It is reflecting the light from the Sun.
Describe the sunrise/sunset cycle.
This is evidence of Earth's rotation! The Sun appears to rise in the east and set in west because the Earth is spinning counter clockwise. As the Sun moves across the sky shadows change in length: becoming shortest near noon (when the Earth is most directly facing the Sun) and getting longer around sunrise and sunset (as the Earth rotates away).
What movement of Earth signifies 'a year'?
One revolution around the sun
REVIEW!!!

How many 'Moons' can fit in the Earth?
50!
REVIEW!!!
What is solubility?
the ability of a substance to dissolve in another substance, such as sugar dissolving in water
Describe the difference between the two movements earth experiences: rotation vs. revolution.
Rotation is spinning in a circle on an axis. Revolution is traveling in a orbit (or complete path) around another object.
How does the Sun support the Earth?
It gives LIGHT and HEAT energy to our cycles: Water, life, day/night etc.
What is 'special' about Earth's placement in the solar system?
It is in the 'Goldilocks Zone' relative to the Sun making it the perfect conditions to support life.
REVIEW!!!
What is condensation?
the process of water changing from water vapor to a liquid by loss of heat (e.g., weather - water vapor forming clouds)
