Dew Point.
What is the temperature when air becomes full of water vapour and condensation begins?
Precipitation.
What is any form of water that falls from clouds?
The atmosphere.
What is the layer of gases surrounding Earth, held in place by gravity?
Transpiration.
What is it when plants release water vapour from their leaves?
Condensation
What is it when water vapour changes to liquid droplets?
Infiltration
What is water soaking into the ground?
Liquid droplets above 0 degrees Celsius
What is rain?
Evaporation
What is when liquid water changes gas water (water vapour)?
Sublimation
When solid water (ice/snow) changes to gas water (water vapour)?
Condensation nuclei
What are tiny particles (dust, salt, smoke) that water droplets cling to in clouds?
Groundwater
What is water stored underground in spaces between rocks and soil?
Falls as liquid but freezes when it hits the cold ground.
What is freezing rain?
The three main gases that make up the atmosphere.
What is carbon dioxide, oxygen and nitrogen?
What clouds are made up of?
This powers the water cycle.
What is the Sun?
Runoff
What is water flowing over land into rivers, lakes and oceans?
Ice crystals that fall when it's below 0 degrees Celsius
What is snow?
Clouds that hail forms in.
What are cumulonimbus clouds?
Why might the same cloud produce rain in one place and snow in another?
The temperature when the precipitation falls.
What would happen to the water and gas on Earth if there was no gravity.
What is drift off into space, and Earth would cease to be inhabitable?
When rain freezes as it falls
What is sleet?
Lumps of ice that form in thunderstorm clouds
What is hail?
Cloud Formation
What is:
1) The Sun heats water → evaporation makes water vapour. 2) Warm moist air rises (updraft). 3) Rising air cools. 4) At the dew point, condensation happens. 5) Water vapour sticks to condensation nuclei → droplets/ice crystals form. 6) Many droplets together = a cloud.
Rain Shadow Effect.
What is when moist air hits a mountain and rises. Rising air cools and makes clouds and precipitation on the windward side. After the air passes over the mountain, it sinks, warms up, and becomes dry.
Why forests affect weather and rainfall?
Because more trees leads to more transpiration and more water vapour ascending into the atmosphere, leading to more cloud formation and precipitation.
