i think the reason was because of the pangea theory that continents where once one big continent and over time it began to split
They depend on it because this helps them maintain nutirance and survive and reproduce more.
D transferring electrons because that causes electricity
A ball kept on 3rd floor of a building.
A pendulum bob kept at 3m height
A stone thrown vertically upward.
A pressed spring.
A squashed spunge ball.
The energy carried by one photon is directly proportional to its
frequency. So the photon energy is greatest for the electromagnetic
waves with the highest frequency / shortest wavelengths.
That's why when you get past visible light and on up through ultraviolet,
X-rays, and gamma rays, the radiation becomes dangerous ==> each
photon carries enough energy to tear electrons away from their atoms,
ripping molecules apart and damaging cells.
The photon with the highest energy is a gamma-ray photon.
