Which of the following best describes the orbits of the planets?
1. The sun is the center of the solar system and all planets orbit around it with elliptical orbits.
2. The earth is the center of the solar system and all planets orbit in perfect circles around it.
3. The earth is the center of the solar system and all planets orbit around it with elliptical orbits.
4. The sun is the center of the solar system and all the planets orbit around it in perfect circles.
Which of the following does not support the idea that the solar system formed from a giant nebula?
1. all planets spin the same direction (except Venus and Uranus) and the planets all orbit the same direction.
2. the planets are all coplanar (except Pluto)
3. some planets are dense and small and rocky, some planets are light (low density) and very large, and gaseous.
4. Trick Question. All of these are true and support the idea that all planets formed from a swirling planetary nebula.
Why are the terrestrial planets denser than the gas giants?
1. Wrong Mr. K, the gas giants are much bigger
2. Iron condenses at higher temperatures than hydrogen and other gases.
3. volcanoes on the sun made them that way
4. hydrogen float the top of the solar system. It is less dense than air.
Which theory for the origin of the moon also explains the tilt of earth’s axis by 23.5 degrees?
1. The moon was formed from a little bit of the same material in the planetary nebula that the earth was. It might be like a drip of pancake batter falling on the griddle next to a full sized pancake.
2. The moon was “spun off” of the earth early on before the earth solidified. The spun off material was blob-shaped and became the moon. The earth has been wobbling ever since
3. The moon was captured by the earth's gravitational field. The gravity of the moon has pulled the earth over resulting in a tilted axis.
4. The earth was hit by asteroid, The melted asteroid and parts of earth splashed into space. This debris came together to form the moon. The impacted tilted earth's axis.
Which of the following correctly describes a solar elcipse.
1. In a solar eclipse you can't see the moon, the earth passes between the moon and sun.
2. In a solar eclipse, you can't see the sun. It stops shining and reboots.
3. In a solar eclipse, you can't see the moon. It passes behind the sun.
4. In a solar eclipse, you can't see the sun, it is blocked by the moon passing in front for a few minutes.
On the following diagram, which position corresponds to winter in the southern hemisphere?
1. Position 2
2. Positon 1
3. Position 4
4. Position 3
The earth has four seasons per year because?
1. The earth gets very near the sun and then very far away.
2. The carbon dioxide builds up in summer time, this causes global warming in summer.
3. The earth's tilt means that once a year the northern hemisphere has the sun's rays striking it at right angles. This heats up the northern hemisphere, while the southern cools.
4. The sun has 4 cycles per year, and varies between high and low output.
