Types of Weather
What speed does a hurricane need to reach in order for it to be considered a hurricane?
73 mph
Which weather instrument measures humidity?
Psychrometer/Hygrometer
True or False: Warm air creates high pressure areas.
False
Describe a convection current.
A convection current is when hot air rises up. When it cools, it sinks back down and heats up again, and the process goes over and over again.
What is the most dangerous part of a tornado?
The flying debris
What does a Weather Vane measure?
It measures the direction of the wind.
Can air travel from a low pressure center to a high pressure center?
No
What are the three ways that a cloud can be formed?
Convection, Lifting, and Frontal Activity.
What type of weather is considered severe if wind speeds are more than 58 mph?
Which instrument measures in Degrees? (Hint: Fahrenheit or Celsius)
Thermometer
Which pressure area would be more likely to have rain: a high pressure area or a low pressure area?
A low pressure area.
True or False: Clouds are tiny droplets of water that are in the sky.
True
What is the center of a hurricane called?
The Eye
Which instrument measures air pressure: anemometer or barometer?
Bonus: name what the wrong instrument measures.
barometer
bonus: Anemometers measure wind speed.
What is wind?
Wind is the movement of air from a high pressure center to a low pressure center.
How does hail occur?
The droplets of water freeze and more droplets get fused to the pieces of ice until they are too heavy to stay in the cloud.
Which type of weather has lightning: Tornadoes or Thunderstorms?
Thunderstorms
Does mph/kph measure wind speed or air pressure
wind speed
True or False: Cold air sinking creates a high pressure area.
True
True or False: A cloud that has a lot of water in it is white. (This isn't on the quiz. I just wanted to test you!)
False
