Weather and Climate I: Basic Elements
Item WC081002: As cool air moves toward warmer air, the cool air can push the warmer air upward, which causes the warmer air to cool, condense, and form clouds.
Cool air is blowing from Location 1 toward Location 2, where the air is warmer. When the air that was at Location 1 reaches Location 2, clouds begin to appear. If there is no increase in the amount of water vapor in the air as it moves, what could explain why the clouds appear in the air at Location 2?
- The cool air pushed the warm air upward, which caused the warm air to cool, condense, and form clouds.
- The cool air pushed the warm air upward, which caused the warm air to become warmer, condense, and form clouds.
- The warm air pushed the cool air upward, which caused the cool air to become warmer, condense, and form clouds.
- The clouds must have moved from somewhere else because air without clouds cannot turn into air with clouds.
