Rule 1: Every nonzero digit is significant.
Rule 2: Zeros appearing between nonzero digits are significant. These are called “sandwich zeros”.
Rule 3: Trailing zeros follow a non zero digit and are significant only if there is a decimal point.
Rule 4: Zeros to the left of the first nonzero digit are insignificant. These are called Placeholder zeros.
What are the numbers of significant figures for the following numbers:
0.003048 5010.0
0.003048 = 4
5010.0 = 5

Solar Intensity
300
What are the 6 Layers of the sun in order?
Core, Radiative Zone, Convective Zone, Photosphere, Chromosphere, Corona
300
Why do we only see one side of the moon?
Synchronous rotation
400
What are Qualitative and Quantitative Data. What are some examples of each?
Qualitative Data - descriptions, observations , EXAMPLES: hair color, eye color, taste, smell, things you see,
Quantitative Data - Numbers, tables, graphs, EXAMPLES: Percentages, height, mass
400
Causes the winds to move in a curved path due to earths rotation.
Coriolis Effect
400
Areas of High Temperatures have what type of pressure systems? Why?
Low Pressure Systems, because the hot air rises expanding over the area.
400
Explain the difference between a meteoroid, meteor, and a meteorite.
Meteoroid is in space broken off an asteroid
Meteor is in the Earth's Atmosphere (shooting star)
Meteorite is when it touches the Earth's Surface.
400
Of all the planets in the solar system, besides Earth, which one would be the best place to colonize and why?
Mars
Similar atmosphere
Signs of water in the form of ice

Inside a greenhouse, different types of trees are kept at 3 different humidity levels. These are left for 3 years. One tree is left outside in normal conditions. The heights of the trees are measured once a week.
IV:
DV:
Constants:
Control:
IV: different trees and different humidity
DV: height of trees
Constants: green house, 3 years
Control: the tree left outside

What are the 5 main Factors that affect the weather.
Temperature, Air Pressure, Latitude, Wind, Fronts
500
Large body of air containing the same humidity and temperature.
Air Mass
500
If we wanted to colonize the moon, what would be the two biggest problems we would face?
Lack of Oxygen (no atmosphere)
Very Little Gravity
500
Why does the moon not have liquid water? This is one of the main reasons.
It is too cold on the moon and it turns into ice, low gravity which means no atmosphere.
