the theory that matter could be changed into energy was introduced by who
Albert Einstien
the act or process of burning
combustion
a form of stored solar energy made from marine, animal, and vegetable life
petroleum
the sun is made mostly out of what
hydrogen
energy given of by atomic reactions taking place inside the sun
solar energy
A great amount of scientific evidence is available to indicate that coal:
represents uprooted vegetation buried by flood waters
It is more logical to believe that the complex life sustaining processes of the sun-Earth system were created because they rely on one another.
true
The sun's energy comes from the burning (combustion) of hydrogen like a huge fire.
true
The energy conversion process of nuclear fusion appears to best explain the source of solar energy.
true
nuclei combinations
mass converted to energy
E = mc²
are related to nuclear fusion
The sun's energy is released when mass is converted into energy
true
Observing the sun's light through a spectroscope has indicated that the sun contains large amounts of:
hydrogen
The temperature of a place greatly affects the _____ of that region.
climate
weather
The remains of vegetation of long ago has formed _____.
coal
petroleum
Photosynthesis provides what needed for human respiration.
oxygen
The sun's energy is the result of a nuclear reaction
true
Splitting the atom proved the equation E = MC 2, which was formulated by the mathematician ________ ______________
albert einstein
Hydroelectric energy comes from:
rivers
The sun's energy is released when ______ is converted into energy.
mass
Solar observations confirming the shrinking sun indicate that the sun _____.
is relatively young
