Precipitation
How many types are there?
4
Clouds can't happen without...
1. Cloud seeds
2. Warm air/water rising
3. Cold Temps.
What temperature does ocean water need to be to form hurricanes?
At least 80 degrees
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
How many categories of hurricanes are there?
5
What does cold air do?
It sinks
The energy of motion.
Kinetic
What is the only liquid type of precipitation?
Rain
Why don't all clouds become storm clouds?
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
Hurricanes involve what type of clouds?
Cumulonimbus
What do the layers in some hailstones show us?
How many updrafts the hailstone got caught in
Large storms that form over oceans with water at a temperature of at least 80 degrees.
Hurricane
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)
What is the main difference between hurricanes and tornadoes? (There are 2 acceptable answers, but you only need to give one.)
1. Size (hurricanes are much larger than tornadoes)
2. Hurricane form over oceans, tornadoes form over land)
What effect do strong updrafts have on hailstones?
The stronger the updraft, the bigger the hailstone
The amount of water vapor in the air.
Humidity
You can't have precipitation without...
1. Cloud seeds
2. Warm air/water rising
3. A big temperature difference between air close to the ground and air high up in the atmosphere
4. Evaporation
Name three things that can act as cloud seeds.
Sand, dust, pollen, dead skin cells, volcanic ash, salt from ocean water, etc.
The spinning of the Earth causes what in hurricanes and tornadoes?
It causes updrafts and downdrafts to spin around each other, creating very high winds.
What causes thunder?
Lightning
A large storm cloud.
Cumulonimbus
