What provides the initial source of energy for photosynthesis?
All energy needed for photosynthesis comes from the sun.
Is a grape drying in the sun a chemical or physical change?
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
Where is sun energy at on the water cycle illustration?
Sun energy is used to evaporate water. This is the initial step of water cycle.
Do The skin helps production of vitamin c by using ultraviolet rays from the sun to form an initial molecule of vitamin c that matures in the liver?
No, the process listed is true for vitamin D, not vitamin C.
Would it be possible for gas giant to form close to the sun?
Most likely not. Too close to the sun, heating is too intense for hydrogen and easily vaporized substances to remain in place. These materials would then be swept outwaard by the intense solar wind of a young sun. As a result, there is fairly plentiful water and ice in the outer solar system to form gas giants, while terrestrial planets form from the leftover rock and metal in the inner solar system.
What do you need to start a rainbow?
The 2 main substances needed to start a rainbow are water and sun.
What provides the initial source of energy for photosynthesis?
All energy needed for photosynthesis comes from the sun.
Why does an asteroid not develop a tail when its closer to the sun?
Comets develop a tail as the sun's energy vaporizes substances such as ice and dry ice that form the comet. Asteroids lack these substances and so do not devlop tails.
Where does the energy needed by plant to make food come from?
From the sun. It's solar energy
Where does the energy needed by the plants to make food?
From the sun - in the form of sunlight.
What factors allowed the sun to form in the solar system?
the gravitational forces from nearby solar systems allowed a nebula to form and in that nebula were all the compounds needed to form the sun and planets.
the initial source of energy?
the sun
Why does a comet have no tail?
Comets that seldom visit the sun have water and other volatile substances evaporate from their core. Those substances form a long tail out from the core as the solar wind blows them away from the comet. If a comet makes a number of trips around the sun, all of its volatile substances are blown away and it can no longer have a tail.
Where does the initial source of energy come from?
the sun
What is needed to form the sun?
All that's really needed to form a star is a lot of hydrogen. Everything else will take care of itself.Our Sun is "metal-rich", meaning that it has some elements heavier than hydrogen and helium in it. However, it's mostly hydrogen, and most of the rest is helium.
The Aztecs believed the sun needed what?
They belived that the sun needed human blood so that is why they sacrificed it
Is a grape drying in the sun a chemical or physical change?
It is a chemical change. Fermentation causes bonds to break within a compound and new bonds form thus chemically changing the initial 'reactant'.
