What is precipitation?

• Liquid water gaining energy and turning into water vapor which rises higher in the atmosphere.

• Water vapor being given off by plants as a byproduct of photosynthesis.

• Water vapor losing energy and turning into liquid water droplets forming clouds.

• Any form of water that falls from the sky.

Which statement describes the movement of air particles based on heat in the atmosphere?

• Cool air is heated by the Earth's surface which rises higher in the atmosphere, cools off, and sinks back down to Earth to be reheated.

• Warm air is cooled by the Earth's surface which rises higher in the atmosphere, warms up, and sinks back down to Earth to be cooled again.

• Warm air is heated by the Sun which sinks lower in the atmosphere, cools down, and rises back up to be reheated.

• Cool air is heated by the Sun which rises higher in the atmosphere and stays there.
