Gravity is one reason but also it depends in the speed, if the wave is fast, it will go higher and then bend. hope i helped :D
Answer:
The transfer of energy through empty space is called convection.
Explanation:
One of the fundamental laws of the universe is the conservation of energy. Energy can't be created and it can't be destroyed. Convection can be the process by which heat is transferred . Temperature is known as the basic principle of heat transfer. The amount that how much of thermal energy can be available is determined by the temperature, and the heat flow represents movement of thermal energy.
The order is:
interphase
prophase
metaphase
anaphase
telophase
(the way i remember it is "IPMAT")
Polymerization would be the answer you're looking for.
