Multiple Choice
What is Kepler's first law?
3
Once upon a time there was a dude.
His name was Ptolemy.
He stared at the sky a lot.
From his observations, he deduced that everything HAS to revolve around the Earth right?
4
Centric=center
5
This assumption was based on phenomena known as retrograde motion.
This is the "apparent westward motion of planets with respect to the stars".
6
When really we were doing this...
7
Multiple Choice
What is the apparent westward motion of planets in relation to the stars?
8
Multiple Choice
Why do we still learn about Ptolemy if he was wrong about the geocentric model?
9
...about 1,500 years to be exact...
10
He's Copernicus.
see..?
11
Based on previous theories established by Aristarchus (310-230 BCE), Copernicus maintained that Earth spins on an axis and revolves around the Sun.
So other planets such as Mars must also follow suit.
12
13
Multiple Choice
Who originally presented the idea of a heliocentric model?
Aristarchus
14
Multiple Choice
How is the heliocentric model different from the geocentric model?
15
The spinning of a planet on its axis
16
The 24 hrs we as a society call "1 day".
The actual time it takes to complete one full 360 degree rotation.
24 hours
23 hours 56 min 4 sec
17
Multiple Choice
What is the sidereal day and how does it differ from the mean solar day?

As the Earth orbits, different parts of Earth are exposed to the sun.
the Earth tilts on an axis
23
24
Summer occurs in the hemisphere that has the most sun exposure.
25
Multiple Choice
What season is it in the United states when the Sun shines on the southern hemisphere?
26
As the Earth orbits around the Sun, so does the moon around the Earth.
27
28
Tides: as water moves around the Earth.
This is influenced by the position of the moon around the Earth.
29
Tides: as water moves around the Earth.
This is influenced by the position of the moon around the Earth.
Primary force comes from the Moon's gravity
30
Tides: as water moves around the Earth.
This is influenced by the position of the moon around the Earth.

39
Multiple Choice
Why are the equator and poles at different temperatures?
The angle of the axial tilt.
Because of the Earth's rotation speed.
Earth's distance from the sun.
The difference in sun exposure.
40
Multiple Choice
What happens when the Earth's axis is tilted toward the Sun?
It's summertime in the southern hemisphere.
It's summertime in the northern hemisphere.
It's wintertime in the southern hemisphere.
It's wintertime in the northern hemisphere.
41
