Water Cycle
TRUE OR FALSE Hail tends to happen on days when the temperature is warm and the humidity is down.
FALSE - When temperature is warm and humidity is UP
What powers the water cycle?
What is humidity?
The amount of water vapor in the air
As you go up a mountain the temperature goes...
down
What is volume?
How much space an object takes up.
Water turning from vapor into rain droplets is an example of what process?
condensation
The sun changes the state of water from a liquid to a gas in what process?
Evaporation
You observe falling precipitation. The temperature is 60°F and the wind speed has suddenly increased. What type of precipitation do you most likely observe?
hail
As altitude increases, temperature
Decreases
What is density?
How tightly packed the particles are.
What processes put water vapor into the atmosphere?
evaporation
Rain, sleet, snow and hail are examples of what process?
precipitation
What are the 4 indicators that a hailstorm occurred?
Temperature drops while humidity, wind speed and wind gusts all go up.
Why is air near the ground warmer than air higher up?
The ground absorbs the sun's heat and then acts as a heater to the air
When you increase volume, what happens to density?
It decreases
plant leaves losing water
transpiration
List the steps of the water cycle.
Evaporation, condensation, precipitation, collection
What is the relationship between air temperature and the amount the amount of moisture it can hold?
Direct relationship - when temperature increases, the amount of moisture it can hold also increases.
As elevation increases, what happens to the air's density?
It increases, because the temperature decreases.
When you heat up air, what happens to its density?
it decreases
On a cold day in winter, Jasmine breathed on the cold car window. The window fogged up enough so that she could write her name on the glass with her finger. Why did the fog form on the window?
B. The moisture in her breath condensed when it hit the cold glass.
How are clouds formed?
Water vapor that has condensed onto CCN
What 3 conditions produce large storms?
Very cold high level temperatures, warm low level temperatures and high humidity.
What is an updraft?
Warm air rising in the atmosphere.
Explain what convection current in the atmosphere is.
Warm air rising and cold air sinking, creating a circular motion.
