Liquidcan be throttled. Solids can't.
Liquid can be restarted (turned off and on again). Solids can't.
Liquid fueled rockets get it from liquid oxygen, and solid fueled rockets get it from and oxidized metal.
There are two main types of rockets: liquid-fuel and solid-fuel. Liquid-fuel rockets consist of a fuel and oxygen (or other oxidizer) in liquid state. They are combined in a combustion chamber and ignited. The fuel flow to the engine can be controlled, the amount of thrust produced can be regulated and the engine can be turned off or on as needed. Solid-fuel rockets consist of a fuel and oxidizer that are pre-mixed in a solid form. Once the solid fuel is ignited, the resulting thrust cannot be regulated or turned off. This fuel system is simpler, safer, and cheaper-but less efficient-than that of a liquid-fuel rocket.
The two main types of rockets are, Solid Fuel and Liquid Fuel
The three kinds of rockets are solid fuel rockets, liquid fuel rockets, and ion powered rockets.
unlike solid fuel, liquid fueled rockets are capable of being throttled, shut down, and restarted.
it's the comparison between the fuels used, solid / liquid

The earliest rockets--i.e., those built by the Chinese as early as the 14 century--used solid fuel.

Only two: solid liquid fuel
Both liquid and solid fuel rockets are used for manned flight today.
The motion of particles in a solid are much slower than those in the gas. Gaseous particles are very energetic and highly kinetic.
The answer, is that there are only two types of rockets which fuel modern spacecraft. they are solid fuel rockets, and liquid fuel rockets
