What two gases is the sun mostly made of? | 71% Hydroge and 21% Helium |
Where is the energy of the sun made? | in it's core |
What is the temperature in the sun's core? | 10,000,000 to 20,000,000 |
What is the pressure like in the sun's core? | more than 1,000,000,000 times |
What is the layer after the core? | radiation layer |
How long can it take for the energy to move out of the radiation region? | millions of years |
What happens in the convection layer? | Gasses with different energies move in circles |
What is the photoshere? | it is the visible surface of the sun made up of a layer of gasses |
What is the temperature of the photosphere? | 5,730 C or 10,346 F |
What is the inner layer of the Sun's atmosphere called? | chromosphere |
What color is the chromoshere | red |
What is the name of the outermost layer of the Sun's atmoshere? | corona |
What is a solar flare? | bursts of heat and energy |
How do solar flares affect the Earth? | they send out radiation affecting sattlelights and tv's |
What is the aurora borealis? | different colored lights in the atmosphere also called Northern Lights |
Solar Flares are sometimes assoiated with sunspots. What are sunspots? | regions of the photosphere that have a lower temperature |
In words what is E=mc | energy = mass speed of light |
What do you call the smashing together of particles to make energy? | fusion |
How does the sun make its energy? | when hydrogen particles combine to make helium |
What happens to the mass that is loss when particles collide? | it is changed to energy |
What lies at the center of the solar system? | the sun |
What objects in space are included in the solar system? | eight planets |
Name te first four planets, the inner planets, in order from nearest to farthest from the sun. | Mercury, Venus, Earth, Mars |
Name the outer four planets in order from nearest to farthest from the sun | Jupiter, saturn, uranus |
What is a telescope? | instrument that uses lenses to see distant objects. |
What is a moon? | an object that circles around a planet |
What is the name of the largest moon in the solar system? | Gunymede |
Where is the largest moon found?` | Jupiter |
What is another name for a moon? | Satellite, an object in space that circles around another object |
What is a man made satellite? | They circle around earth to provide weather information and commuication systems |
Whay does themoon have somany craters in comparison to the Earth? | It has no atmosphere so the objects that fall toward it do not burn up |
What is an asteriod? | A rock that revolves around the sun |
Where are most asteroids found? | between marsand jupiter |
What is a comet? | a mixture of frozen gasses ice dust and rock |
How is a comets tail made? | it is produced by energy from the sun |
What happens to a comet's tail as it nears the sun? | It blows away from the comet |
What are the other small objects in space called? | meteroids |
What are meteroids called when the enter the Earth's atmosphere? | meteors |
What is the basic definition of Gravity? | a force of attraction between 2 objects |
What are the two things that affect the strength of gravity? | mass and distance between 2 objects |
Compare the moons Gravity to the Earth's | the moons gravity is about 1/6 that of the Earth's |
What is weight? | amount of mass X gravity |
What is an orbit? | a path that one object takes around another object |
How are planets held in their orbits around the sun | by inertia |
What is inertia | the tendancy of a moving object to keep moving in a straight line |
Why do the planets not fall in towards the sun because of gravity? | Because inertia and gravit makes Earth orbit the un instead of gravity pulling it into the sun and inertia makes it go in a straight line |
In what type of circular orbit do planets orbit around the sun? | the ellipse orbit |
what is the difference between to rotate and to orbit? | orbit makes an object move around another object and to rotate makes it rotate to a different side |
What causes tides on Earth? | The sun'sgravity pulling the Earth and the moons gravity pulling the Earth |
when do high tides occur? | twice a month when the sun and moon line up and both pulls are added together |
When do low tides occur? | When the moon pulls the water on the side nearest to it away from the land |
