Water Cycle
What process turns liquid water into water vapor?
Evaporation
What do clouds form from?
Tiny droplets of water or ice crystals
Which storm includes thunder and lightning?
Thunderstorm
What is erosion?
The movement of weathered material.
Name one stage of the water cycle and describe it.
Evaporation (water turning to vapor), Condensation (vapor forming clouds), Precipitation (water falling as rain, snow, etc.), and Collection (water gathering in rivers, oceans, or underground).
What process forms clouds when water vapor cools?
Condensation
What happens to warm air?
It rises
Which severe weather forms over warm ocean water?
Hurricanes.
What causes erosion?
Water, wind, ice, or gravity.
How do clouds form?
Water vapor cools and condenses into droplets.
What process brings water back to Earth as rain, snow, sleet, or hail?
Precipitation
What type of air pressure usually brings stormy weather?
Low Pressure
Which storm has the strongest winds but is usually smaller than a hurricane?
Tornado.
What is deposition?
When eroded material is dropped in a new place.
What role does the Sun play in the water cycle?
It provides energy for evaporation.
Put the 4 water cycle stages in order.
Evaporation → Condensation → Precipitation → Collection
Why does wind occur?
Air moves from high pressure to low pressure
What conditions help severe storms form?
Warm, moist air and rising air.
How are erosion and deposition connected?
Erosion moves material, deposition drops it.
Explain how water can change Earth’s surface.
Through erosion and deposition.
How can water from a puddle end up in the ocean?
Evaporation, condensation, precipitation, runoff into rivers, then the ocean
Why are clouds important for precipitation?
They collect water droplets that eventually fall as rain or snow.
Name one safety rule for severe weather.
Go indoors, avoid windows, listen to alerts (answers may vary)
A river slows near the ocean and drops sand. What process is happening?
Deposition
Explain how a snowman could end up in the ocean.
Melts → runoff → rivers → ocean
Melts → Evaporation → Condensation → Precipitation
