11
What is the Big Bang Theory?
It is the theory of how the Taco formed
It is the Theory that the Sun orbits around the the Earth
It is the theory that we are not alone in the Universe
It is the Theory of how the Universe Formed
12
What is the independent variable?
Number of cars sold
Money earned
13
how does a barometer work
as air pressure increases, liquid contracts and lowers in a glass tube
as the temperature increases, the liquid level raises
air pressure pulls lead down into a dish
air pressure pushes mercury into a glass tube
14

Triangle
Square
Circle
Ellipse
15
Where are the trade winds located?
Above the Poles
Near the Equator
Near the Poles
Halfway Between the Equator and the Poles
16
What causes a thunderstorm to form?
Just a cold front
Both a warm and cold front
Fronts don't cause the formation of a thunderstorm
Just a warm front
17
How are asteroids formed?
They were always here when the galaxy started
They formed from leftovers of the creation of solar system, stayed smaller
They formed when a moon breaks free of a planet
Formed when the Sun ejected large pieces of rocky material
18

a period of below-average precipitation.
21
what shape are cumulus clouds?
rough
puffy
flat
hard
22
How do oceans impact climate?
The oceans have very little impact on overall climate
The oceans keep heating evenly distributed throughout the Earth
Keep tropics warm by bringing more rain
Redistribute uneven heating of Earth oceans absorb heat and bring elsewhere
23
How are atoms formed?
After Big Bang, lighter elements combined to create larger, complex atoms
Stars exploded creating new atoms
Larger elements broke down after the Big Bang
All atoms are formed during supernovas (high energy conditions)
24

4.6 million years ago
1 million years ago
13.7 million years ago
26
Why is the Big Bang the most accepted theory about how the Universe was formed?
It has religious and scientific evidences.
It has many lines of acceptable evidence.
It has mathematical proof.
It has not been revised for a very long time.
27
