Why is Earth often referred to as the 'blue planet'?

• Because it is the largest planet

• Because it has a lot of water

• Because it is closest to the sun

• Because it is covered with forests

What percentage of Earth's surface is covered by water?

• All of it

• Three quarters

• Half

• One quarter

What is the water cycle?

• A method to clean water

• A journey of water from the ground to the sky and back

• A way to store water

• A process where water is created

What is the first stage of the water cycle?

• Precipitation

• Infiltration

• Evaporation

• Condensation

During evaporation, what happens to water?

• It turns into vapor and rises

• It becomes visible steam

• It stays in the ocean

• It turns into ice

What forms when water vapor cools in the atmosphere?

• Fog

• Snow

• Clouds

• Rain

What is the process called when water vapor turns into clouds?

• Condensation

• Evaporation

• Sublimation

• Precipitation

What happens during precipitation?

• Water vaporizes

• Water freezes

• Clouds disappear

• Water falls as rain or snow

How does precipitation contribute to the water cycle?

• It evaporates immediately

• It replenishes rivers and lakes

• It forms clouds

• It creates new water

What is the significance of groundwater in the water cycle?

• It is not part of the cycle

• It evaporates quickly

• It forms clouds

• It provides water to plants and streams
