|
earth, moon, sun, Mercury, venues, mars Jupiter and Saturn, 5 planets and sphere of stars, All revolve around the earth. The man who first proposed this model was Ptolemy.

v Explain the view of the solar system that Copernicus developed? What is this model called?
|
The solar system that Copernicus had developed was Nicholas Copernicus in 1543. The model is called Heliocentric- sun is the center of the solar system. This is the view of the solar system, Moon revolves around the earth; earth and moon revolve around the sun Daily movement of the sun and stars caused by rotation of the earth.

|
Why doesnt Mercury have craters?
|
there is no atmishpere, which and it protects and burns up the mediors, it has no weather or water to aroud them, close to the sun
|
|
|
Why is Mercurys sky black?
|
There is no atmisphere to scatter the light
|
|
|
What is special about Venus's rotation?
|
It roatates clockwise while all others rotate counter clockwise
|
|
|
Why doesn't earth have any craters?
|
Earth has a atmosphere to burn them up. And earth has weather and water so the craters cant erode
|
|
|
Name 4 reasons we are intrested in mars
|
1. It has a simillar train
2. There are ice caps on its poles 3. Similar atmisphere 4. its close to us |

|
because the Moon revolves around the earth; earth and moon revolve around the sun Daily movement of the sun and stars caused by rotation of the earth.
|
|
|
What happens to the distances between the planets as you get farther from the sun?
|
you lose some gravitational pull of the sun so the planets should get further away
|
|
|
What are 4 discoveries that Kepler made about planetary motion?
|
The balance between gravity and inertia work together to keep planets in orbit Sun has over 99 % of the mass in solar system Gravity from sun keeps planets in orbit Inertia keeps planets from being drown into the sun.

|
b/c the rocky ones are heavier and they did not get pushed away by the solar winds from the sun
|
|
|
wat r kelpers 3 laws
|
- eliptical
- suns not center in the orbit - travles slower speed |
|
|

|
|
|
Were do comets come from?
|
the oart cloud and kuiper belt
|
|
|
How did the sun start to burn?
|
gravity puled the mas in the more mass = more gravity then compacted and so much pressure makes it burn
