2 When you ride your bike uphill, where does the energy you use come from?
A) from the food you eat
B) from the exercise you do
C) from the push of the ground on the
bicycle -
D) from the pull of gravity on you and
the bicycle

The answer is (A)

Explanation:

The energy is in motion, so it is kinetic energy, and it is derived from the food we digest. At the top of the hill, in the absense of motion, the kinetic energy converts to potential energy.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
