Evaporation
What process changes liquid water into water vapour?
Evaporation
What process changes water vapor into liquid water?
Condensation
What is water that falls from clouds called?
Precipitation
Where can water collect after precipitation?
Oceans, lakes, rivers, soil, glaciers, etc.
What is the continuous movement of water on, above, and below Earth's surface called?
The water cycle
What energy source mainly causes evaporation?
The Sun
What forms when water vapour condenses high in the atmosphere?
Clouds
Name two types of precipitation.
Rain, snow, sleet, or hail
Name one example of surface water.
Lakes
Put these in order: condensation, evaporation, precipitation.
Evaporation → condensation → precipitation
What happens to water molecules during evaporation?
They gain energy and escape into the air as water vapour
Why does condensation often occur when air cools?
Cool air holds less water vapor
How does snow differ from rain?
Snow is frozen precipitation; rain is liquid
What is groundwater?
Water stored beneath Earth's surface
What process do plants use to release water vapour into the atmosphere?
Transpiration
Name one place where evaporation occurs.
Oceans, lakes, rivers, puddles, etc.
Give an everyday example of condensation.
Water droplets on a cold glass
What conditions can cause precipitation to fall as hail?
Strong thunderstorms/updrafts can freeze water into ice
How can water from a river eventually reach the ocean?
Rivers flow downhill and eventually into larger bodies of water/oceans
How does the Sun power the water cycle?
The Sun provides energy for evaporation
Why does evaporation happen faster on a hot, windy day?
Heat provides more energy, and wind removes moist air
How is condensation important for cloud formation?
Water vapor cools and forms tiny droplets that make clouds
Why does precipitation play an important role in the water cycle?
It returns water to Earth's surface
Why is collection important to the water cycle?
It stores water and makes it available for the cycle to continue
Water evaporates, condenses into clouds, falls as precipitation, and collects in bodies of water.
