Geothermal energy is an alternative energy source. however, it is not resourceful enough to replace more than a minor amount of the earth's energy needs. why is this? a. once the cool water is poured down the well and filters through the rocks, the rocks cool off and are no longer hot enough to turn water into steam. b. drilling through the earth to reach areas hot enough to create steam is possible, but very expensive and difficult. c. the center of the earth is not hot enough to make a significant energy contribution. d. there are only a few places where the earth's core is hot. it is cool in places like antarctica.

geothermal energy is an alternative energy source.however, it is not resourceful enough to replace more than a minor amount of the earth’s energy needs. reason being the drilling through the earth to reach areas hot enough to create steam is possible, but very expensive and difficult.

heat is a form of energy. geothermal energy is the heat which is contained in the earth and generates geological phenomena. from the genesis of earth core which was the ultimate source of geothermal energy were nickel and molten iron.

the gravitational energy which was present at the time of formation is where the energy to heat the core came from.geothermal is a good source of alternative energy because it is renewable, it does not harm the environment, it does not run out, it is the natural resource and it is free.

not sure if this what   you'r looking for would be percent composition

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products
