What causes a tornado to form?
thunderstorms
|
What is a vortex?
spiraling gas or liquid
|
Main source of heat energy for the earth?
the sun
|
How does warm air move?
rises
|
Sky conditions for high pressure?
clear
|
True / False States along the coast are in Tornado Alley.
false
|
Give one way a tornado and hurricane are different.
size, where they occur, wind speed, speed of storm
|
Give one of the two ways you can make the Soil/Water Lab fair.
beakers equal distance from the lamp, make sure the thermometer doesn't touch the beaker
|
What happens to the density of warm air?
decreases
|
Sky conditions for low pressure?
cloudy
|
How are hurricanes and tornadoes similar?
Both have spiraling winds
|
Where do hurricanes form?
over tropical waters
|
Which material heated slower?
water
|
How does cold air move?
settles or drops
|
First step of cloud formation, the sun does what to the water on the earth's surface?
evaporate it
|
True / False The cause of a tornado vortex is uneven heating.
true
|
Where do tornadoes form?
over land
|
Which material cooled slower?
water
|
What happens to the density of cold air?
increases
|
Water vapor rises with warm air and then must do what on dust particles to form a cloud?
condense
|
A tornado will form when this happens? (hint: air masses)
When air masses of different temp and humidity conditions meet
|
Why do more tornadoes occur in Tornado Alley?
has air masses of diff temp and humidity meeting
|
Which material held its heat the longest?
water
|
What is a convection current?
circulation of air caused by uneven heating
|
The final step in cloud formation is millions and millions of tiny "what" droplets gathering together?
water
