Water on Earth moves in a pattern called the water cycle. If a water molecule is deep beneath the surface of the Earth in ground water, how might the water molecules move in the water cycle?

• water molecule will evaporate and return as water vapor in the atmosphere to condense as clouds.

• water molecule will move in underground rivers until it finally reaches the surface of the Earth

• water molecule will remain as ground water for millions of years unless brought to the surface in a well or through plant roots

• water molecule will condense on the solid particles in the soil and eventually surface as a stream or geyser

Timmy & Marsh were investigating what happens when warm and cold air masses meet. They poured hot water (red water) into one side of a divided tank and cold water (blue water) into the other side of the divided tank. What should Carla and Craig observe when remove the divider and the hot and cold water come together?

• cold blue and warm red water mix to form purple water

• hot red water will sink to the bottom and cold blue water will rise to the top

• cold blue water will sink to the bottom and hot red water will rise to the top

• hot red water will stay on one side while cold blue water will stay on the other side

Katie's science class has been studying the water cycle and its relationship to changes in the weather. They learned about factors that affect weather patterns and how weather forecasts are made. After a storm, there was a lot of water vapor in the air. It was a hot day and Katie noticed her shirt felt damp. What atmospheric factor caused the dampness?

• cumulus clouds

• wind

• humidity

• barometric pressure
