Planets
Name the Inner Planets in order from the sun
Mercury, Venus, Earth, Mars
What is missing that makes a planet a dwarf planet?
They have not cleared their orbit
The solar system
A cloud of dust, helium, hydrogen, ice, rock and other material
True or false: Moons are planets satellites?
True, they orbit around planets
Name the Outer Planets in order from the sun
Jupiter, Saturn, Uranus, Neptune
The rings on the Outer Planets are made of:
Ice and rock
Does the Sun have a solid surface?
No, its surface is made of Helium and Hydrogen
That cloud collapsed and started spinning, causing objects to collided into each other. What was formed from high pressure and high temperature, that has a lot of energy and gravity?
The Sun through Nuclear Fusion. Became a stable star.
What is "Space Rock” that is still in space called
Meteoroid
Name 3 things that Planets need to have to be considered a planet
Round, Revolve around the sun, Must have cleared its orbit.
What holds those rings around the Outer Planets in place?
Gravity from the moons
Name the three layers of the interior of the Sun
Core, Radiation Zone, Convection Zone
Small bodies of rock and ice collided and created small?
Planetesimals
Tell me what Comets are made of and then tell me what Asteroids are made of.
Comets: rock, dust and ice
Asteroids: metal and rock
What is unique about Uranus compared to the rest of the planets in the solar system
It rotates and orbits on its side, with poles from end to end, rather than on top and bottom
Huge loops of gas that link different sunspots are called?
Prominences
Where does the Sun produce a lot of Energy?
Its core
Planetesimals that collided together formed other objects in the solar system like moons, asteroids, dwarf planets, comets, and what else?
What is a meteoroid that burns up when it enters Earth’s atmosphere and creates heat and a streak of light (shooting stars) called?
Meteor
The Greenhouse effect takes place on these two planets. Name the two planets and which of the two traps more heat in their already heavy atmosphere.
Venus and Earth; Venus traps more heat
(they usually occur in groups)
Sun Spots
What are layers of the sun's atmosphere, going from coldest layer to hottest layer.
Photosphere, Chromosphere, Corona
The Sun is strong and has strong energy at the center. This pulled the materials left after the sun's formation using what force?
Gravity
Solar wind pushes particles from the sun throughout space. When they enter earths Atmosphere they burn and glow. Where do they enter the Earth's atmosphere at and what does this cause.
North and South Poles; causes the Auroras
