Space Flashcards
Gravity Calculation
weight = mass x gravity Gravity = weight divided by mass Mass = weight divided by gravity
Inner planets are usually…
Rocky and terrestrial and warmer - Mecury, Venus, Earth and Mars
Outer planets are usually…
Gaseous - mostly made up of gas
Jupiter, Saturn, Uranus, Neputune (and pluto)
Name the order of Planets in the solar system :)
The sun, Mercury, Venus, Eaerth, Mars, Jupiter, Saturn, Uranus, Neptune, (pluto)
Why is Venus hotter than mercury, when mercury is closer to the sun?
venus has lots of glabal warming gasses in it, so it is hotter than it is meant to be.
Why are Satellites important?
there are many reasons, the main one is that they help us predict/see/do weather predictions
If the planet has a small orbit….
If the planet has a small orbit…. it means it is closer to the sun, which makes it warmer
Seasons are made because….
of the tilt of the axis
Days and nights are made because…
of the rotation of the earth - it turns
Why do objects in space move in an orbit?
Because of Gravity
2 types of orbits
Circular - a circle shape
Eliptical - an oval-ish shape
there are …… seasons during the year
4
In summer..
it is summer in the northern hemisphere and it is winter in the southern hemisphere
the longest day of the year in the north equator is called….
Summer Solistice
The moon
It orbits the earth
Less Gravity
It is rock
Has no atmosphere
