Questions
Snow is water in its solid state.
Show answer
Answer: True
Snow forms when water vapor freezes into ice crystals high in the atmosphere and falls to the ground.
What causes water to evaporate from puddles?
- Wind alone
- Heat from the Sun
- Rain falling
- Gravity
Show answer
Answer: Heat from the Sun
Solar energy heats the water molecules until they have enough energy to escape as water vapor.
Water vapor is water in its ___ state.
Show answer
Answer: gas
Water vapor is the gaseous state of water — invisible and lighter than liquid water.
The water cycle repeats over and over forever.
Show answer
Answer: True
The water cycle has no beginning or end — it continuously cycles water through Earth's systems.
Where is most of Earth's water found?
- Rivers
- Oceans
- Ice caps
- Underground
Show answer
Answer: Oceans
Oceans contain about 97% of all water on Earth, though it is too salty to drink directly.
Water can only be a liquid — it cannot freeze or evaporate.
Show answer
Answer: False
Water is remarkable because it naturally occurs in all three states — liquid, solid (ice), and gas (water vapor).
What do we call water that falls from clouds?
- Evaporation
- Condensation
- Precipitation
- Irrigation
Show answer
Answer: Precipitation
Precipitation includes rain, snow, sleet, and hail — all forms of water falling from clouds.
When liquid water freezes, it turns into ___.
Show answer
Answer: ice
Water freezes at 32°F (0°C), changing from liquid to the solid state called ice.
Clouds are made of tiny water droplets or ice crystals.
Show answer
Answer: True
Clouds form when water vapor condenses into billions of tiny water droplets or ice crystals suspended in the air.
In the water cycle, what happens after water evaporates into the sky?
- It turns into soil
- It stays in the air forever
- It cools and forms clouds
- It becomes a river
Show answer
Answer: It cools and forms clouds
As water vapor rises, it cools and condenses around tiny particles, forming the clouds we see in the sky.
