The plants grew less in the summer because of the heated air.
The plants grew less in the winter because of the heavy snow
The plants grew less in the winter because the plants received sunlight at a low angle.
The plants did not change at all in the growing cycle.
The Sun and the Earth
The Earth and the Moon
The Sun and Jupiter
Place 1 is farther north of the equator than Place 2
Place 2 is farther north of the eauator than Place 1
They are the same distance from the equator but Place 1 is east of Place 2
The maximum height of the sun would be different at two places only if something is different about the places, such as one is on a mountain and the other is not.
The North Pole is tilted 23.5 degrees toward the Sun
The north pole is tilted 23.5 away from the Sun
The North Pole is not tilted toward or away from the Sun
The North Pole is tiltede 12.25 degrees toward the sun
In BOTH reactions atoms are split and energy is released
Both reactions produce heat energy.
Neither fission nor fusion reactions produce heat energy
2 Hydrogens react to form Carbon
An example of fusion
A chain reaction
The formation of water molecule
Nuclei can not form any new elements or compounds
Earth revolved around the celestial sphere
The sun was the center of the universe
Earth was a "wanderer"
Earth was the center of the universe
Distance to the sun
Earth's tilted axis
Earth's distance from the sun
Total solar eclipse
Total lunar eclipse
Partial lunar eclipse
The angle does not change at all during the day from morning to evening.
The angle changes rapidly during the morning, changes slowly during the middle of the day, and changes rapidly during the evening.
The angle changes continuously throughout the day from morning to evening.
The angles changes continuously througout the morning and eving but does not change during the middle of the day.
Because sunlight is cooled by the cold air in the winter.
Because sunlight reaches the town at a smaller angle in the winter.
Because sunlight has to pass through more clouds to get to the town in the winter.
Because sunlight has to travel a much longer distance to get to the town in the winter.
The earth spins too fast
The tides are visible from the moon
You can see the rotation and the tilt of the axis of Earth
This video shows no attributes of the Earth.
