Motion is defined as phenomenon in which an object move from one place to another over a time.

Generally there are four types of motion: Linear, rotary, reciprocating and oscillating.

Linear motion: In this motion an object moves in a straight line. for example: an athlete running in a straight line.

Rotary motion: In this motion an object moves around an axis. For example: Wheel.

Reciprocating motion: In this motion an object moves in a continuous up and down motion or back-and-forth motion. For example: piston.

Oscillating motion: In this motion an object moves in a swinging motion (backwards and forwards) on an axis. For example: Pendulum.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
