True / False States along the coast are in Tornado Alley.
false
200
Give one way a tornado and hurricane are different.
size, where they occur, wind speed, speed of storm
200
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
200
What happens to the density of warm air?
decreases
200
Sky conditions for low pressure?
cloudy
300
How are hurricanes and tornadoes similar?
Both have spiraling winds
300

water
300
How does cold air move?
settles or drops
300
First step of cloud formation, the sun does what to the water on the earth's surface?
evaporate it

Water vapor rises with warm air and then must do what on dust particles to form a cloud?
condense
500
A tornado will form when this happens? (hint: air masses)

Which material held its heat the longest?
water
500
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
