Planets Flashcards
(19 cards)
What are the 6 facts about the solar system that explain the creation?
1-All planets go around the sun in the same direction.
2-All planets lie on the same plane.
3-All Planets orbit around the sun nearly circular.
4-Most planets rotate on an axis in the same direction as the sun (except Venus, and Uranus).
5-Most planets orbit the same direction as the SUN.
6-Most moons orbit around planets in the same direction.
Mercury
Known for its highly eroded surface Year- 88 Earth days Day- 59 Earth days No atmosphere Water? Yes Temp Range= 662 f to -274 f Tilt=5 d
Venus
Super hot Year- 225 Earth days Day- 243 Earth days Atmosphere makes it hot Temp Range=860 f Tilt=177.3 d
Earth
Golden Zone Life Year- 365 Days Day- 24. Hours Temp Range= 140 f to -130 f Tilt= 23.45 d
Mars
Ice caps of water and carbon dioxide Year= 1.88 Earth Years Day= 24.5 Earth Hours Atmosphere 95% carbon dioxide Water? Yes Temp Range=70 d to -220 f Tilt 25.19
Jupiter
Famous for its 4 big moons Year= 12 Earth Years Day=9 hours and 55 min Temp Range=306 f at 120 miles below atmosphere Tilt= 3.12 d
Saturn
Famous for its rings Year=29.37 Years Day= 10.5 hours Moons-Titan Temp Range=-292 f at top Tilt= 26.73 d
Uranus
Tilted on its side Year= 83.75 years Day= 17.24 days Temp Range=-360 at top Tilt= 97.86 d
Neptune
Blue because of the scattering of light Tilted over 180 degrees enough to rotate backwards Year= 163.73 Years Day= 16.11 Temp Range=-360 f Tilt= 118
What is spectroscopy?
When we look at light through a prism and see absorption or emission spectrums
How can we tell the composition of a planet?
absorption
How can we tell if a planet has a magnetic field?
If it has northern or southern lights.
How can we tell of the condition of the atmosphere of other planets?
The way it effects light (twinkle).
How can we tell the direction of motion?
Light has a doppler effect.
How can we tell the temperature of a planet or star?
The color of light that it is giving off.
What is the frost line?
The point in the universe to where it is not warm enough to melt or burn off gasses.
What do the convection currents do? Where can you find them?
They rotate the air or water or mass in a circular motion because of heat. They can be found anywhere with matter. This effect gives the stripes or layering of climates. It is most visible on Jupiter.
Why is there magnetic fields?
When you have a solid Iron core surrounded by liquid iron it will cause a magnetic force. This is more strong with speed and mass. For example Jupiter spins the fastest so its field is very strong.
Why is Pluto not a planet?
Because it has not cleared out its local neighborhood.
