They don't, they just appear to...an optical illusion.
faster.
because warm air move upwards and cool air due to gravity move closer to the earth surface
Planets and comets move faster when they are closer to the sun.
Planets and comets move faster when they are closer to the sun.
Closer to the sun.
it's gravity
That planet will move faster in its orbit.
The more thermal energy on the liquid, the faster the evaporation, because if they move faster and faster, it is closer to becoming a gas, where the particles move around and try to expand as far as possible.
by the bubbles that are produces the closer the faster the bubles move
Snails move faster on dirt cement
Gravity. The closer a planet is to the sun, the faster it must move to keep from falling into the sun. So note; the closer in; the smaller the orbit AND the faster the speed.
They are denser. Molecules are closer together. Vibrations move faster.
