Stars
The sun and other stars get its energy from _____________.
Nuclear fusion in the core
This is what we call anything orbiting a larger object that is not a star.
Satellite
This affects the strength of gravity when standing on a planet?
Amount of mass
What is the chemical formula for photosynthesis?
6CO₂ + 12H₂O → C₆H₁₂O₆ + 6O₂ + 6H₂O
Carbon dioxide + Water>Glucose + oxygen
What is the outermost layer of the sun?
The corona
This is an area of the sun where plasma is trapped in strong magnetic fields.
Prominence
This is the birthplace of stars.
A nebula
Gravity affects how long a planet takes to revolve around the sun. True/false
False, although the gravity holds the planet in place during orbit it does not affect how long it takes directly.
What is the chemical formula for photosynthesis?
6CO₂ + 12H₂O → C₆H₁₂O₆ + 6O₂ + 6H₂O
Carbon dioxide + Water>Glucose + oxygen
The gravity on the moon is less than the gravity on the earth because of this ....
Less Mass Less gravity.
This is the model of the solar system where the sun is the center of the solar system.
Heliocentric model
Comets have two tails that always point away from the sun because of solar radiation but what are comets made of?
Ice, rock, and Ice.
The mass, although distance from affect the amount of gravity something feels mass is actually what changes the amount of gravity something has rather than how much something feels it.
What is the reactants of photosynthesis?
Carbon dioxide (CO2) and Water (H20)
What star is the brightest to people on earth?
The sun, even though its absolute magnitude is midway up the graph and a yellow star, it is actually closer than any other star making its apparent brightness higher.
This is the type of star with the highest surface temperature.
Type O or Purple color, we associate temperature with color.
This causes gas and dust to form spherical balls in space.
Gravity.
Measuring the strength of gravity you need to know these two things.
Mass and distance between objects.
What are the products of photosynthesis?
Oxygen and glucose
Does luminosity of a star change when moving farther away?
No, luminosity is the absolute magnitude or brightness of the star.
This is the 4 terms we use to classify stars.
Absolute magnitude, Apparent magnitude, size, and temperature.
The earth has many layers including a convection current, the sun also has a convection current, what causes this current?
Heat displacement, Hot air rises and cool air sinks.
What holds an atmosphere to a planet?
Gravity.
Purple/Violet
Atmospheric conditions rely on gravity to help it from escaping into space. True/False
True, gravity pulls on the atmosphere.
