Radiation
There is no energy transformation without energy source. It is that the energy source is not battery. Glow-sticks utilize a chemical energy to generate light so it had internal energy source. Phosphorescence or Glow in the dark stored light energy in the form of electron state and re-emitted the light later. Energy is stored in the molecule and thus its' molecule is the energy source.
Geothermal Energy
The Sun is the main source of energy for convection in the atmosphere and the oceans. The Sun, heat radiated form the Sun is the main source of energy driving convection in the atmosphere and oceans. There is also a small input form geothermal energy.
The preferred source of energy for the heart muscle is fatty acids. Fatty acids are "good fats" that are main sources of energy for cells.
the ocean floor starts to break up just like the land does .
True. Radiation is energy that moves in the form of waves or particles and travels outward in all directions from its source.
Along straight lines, in all unblocked directions
Heat energy travels in all directions in radiation, moving away from the object that is the source of the heat.
A spherical wave travels in all directions, expanding outward from its source like ripples on the surface of water.
Waves that spread out are called diverging waves. This occurs when the wave energy travels in multiple directions away from the source, causing the waves to disperse and move further apart as they propagate through a medium.
Yes, radiant energy spreads out from its source in all directions. This is because it emanates as electromagnetic waves that propagate through space in all directions, radiating energy uniformly outward from the source.
Sound travels away from the source in waves, propagating through a medium such as air, water, or a solid material by causing particles to vibrate. As the particles vibrate, they transfer energy to neighboring particles, thus transmitting the sound wave outward. The sound wave will continue to travel until it loses energy and eventually dissipates.
The location inside the Earth where an earthquake begins is called the focus. The point at the Earth's surface directly above the focus is called the epicenter. The strongest shaking happens at the epicenter.
The source of an earthquake where energy radiates in all directions is referred to as the focus or hypocenter. This is the point within the Earth where the earthquake begins.
Sound gets weaker as it travels because it spreads out in all directions, causing the energy to be distributed over a larger area. This leads to a decrease in the intensity of the sound waves, resulting in lower volume the further you are from the sound source.
Energy is lost as it travels - thus the wave length grows longer. This is usually called 'redshift' as the wave radiated from the source shifts towards the less energetic red end of the electromagnetic spectrum (http://en.wikipedia.org/wiki/Electromagnetic_spectrum). Wikipedia has more information on redshift - http://en.wikipedia.org/wiki/Redshift.
Light travels coincentrically in a sphere from it's source (2-pi steradians solid angle.) That is why light from a candle will shine in all directions.
