Earth's energy endowment appears in what two forms? Answer - Energy flows
and energy fuels. Energy flows are streams of energy arriving at or near Earth's
surface at a more or less steady rate, bringing energy whether it's needed at a
location or not. Energy Fuels are energy stored in one form or another-
commonly as a chemical bond of molecules or in atomic nuclei. Fuel energy
usually remains stored energy until a deliberate act liberates it for usage.
What is the most dominant energy flow? Answer - Solar energy is the most
dominate energy flow, crossing 93 million miles from the sun to earth in 8
minutes and represents 99.98% of all energy arriving to Earth.
What is geothermal energy? Answer - A combination of primordial heat
liberated in the gravitational accretion of matter forming Earth over 4 billion
years ago, energy imparted during the Late Great Bombardment 3.6 billion
years ago, and ongoing decay of radioactive elements, mostly uranium and
thorium.
Other than geothermal energy, what is the only other significant form of earth
energy flow? Answer - Tidal energy, coming from the moon's orbital motion
and Earth's rotation. Gravitational effects cause ocean waters to move back and
forth two times a day. Tidal energy is dissipated, eventually ending up as heat,
as moving water interacts with the shoreline, but only accounts for less than
0.002% of energy flowing to Earth.
