Which of the following energy producing technologies can be beneficial to soil quality?
a. biomass
b. solar
c. wind
d. oil

Both solar energy and wind energy are beneficial to soil quality. They are not using fossil fuels that both harm the soil with digging and fracking, but also are not being burnt which harms the air and can create acid rain. Both solar and wind are using nature to benefit the world. As long as the sun keeps burning and the world turning, we will continue to be able to use them.

Mantle convection is the process that drives plate tectonics. the theory of plate tectonics states that the crust is divided into plates that float on the semi molten mantle below. the circular motion of the magma as it slowly rises and falls or move though convection cells drags the plates along causing them to move. the heat source in the lamp would represent the earth's core. the core is the source of energy that drives convection in the mantle. the lava represents molten magma under the earth's surface. if the lava lamp had floating pieces they would move as the circular motion of the lava in the lamp as it rises and falls would move them along the surface. these floating pieces would represent pieces of the earth's crust.
