Precipitation
How many types are there?
4
Clouds can't happen without... (3 things)
1. Cloud seeds
2. Warm air rising
3. Humidity
How many major parts are there to the water cycle?
3
Name two sources of water in the air.
Oceans, lakes, rivers, streams, creeks, puddles, beaches, glaciers, icebergs, glasses of water, swimming pools, etc.
Air moving upward.
Updraft
Name all the types of precipitation.
Rain, sleet, snow, hail
Cumulonimbus clouds
Sleet is a frozen form of what other type of precipitation?
Rain
What does cold air do?
It sinks
Water vapor turning into liquid water.
Condensation
What is the only liquid type of precipitation?
Rain
Why don't all clouds become storm clouds? (There are 3 reasons.)
1. Not enough cloud seeds
2. Not a big enough temperature difference between air low to the ground and high up in the atmosphere.
3. Not enough humidity
Why can't hail form in the winter?
You need a big temperature difference between the air close to the ground and the air higher up in the atmosphere
What do the layers in some hailstones show us?
How many updrafts the hailstone got caught in
Liquid water turning into water vapor.
Evaporation
What would keep precipitation from falling to the ground?
An updraft with a stronger upward force than the weight of the precipitation trying to fall
Why do we see clouds?
Because when water vapor condenses into liquid water it becomes visible (because it reflects sunlight)
Name two places where evaporation happens from.
Oceans, lakes, puddles, glasses of water, rivers, streams, swimming pools and LOTS of other answers
What effect do strong updrafts have on hailstones?
The stronger the updrafts, the bigger the hailstones
The amount of water vapor in the air.
Humidity
When clouds can't hold any more water, we have...
Precipitation of some kind
Name three things that can act as cloud seeds.
Sand, dust, pollen, dead skin cells, volcanic ash, salt from ocean water, etc.
What effect would there be on the water cycle if Earth didn't have an atmosphere?
We wouldn't have the water cycle at all (because we wouldn't have water)
What causes thunder?
Lightning
A large storm cloud.
Cumulonimbus
