Air Pressure
What happens to warm air?
True or false: There are more forest fires because of climate change.
True
A low air pressure zone is also called a ______.
storm
What is humidity?
the amount of water vapor in the atmosphere
What does a scientist wear to protect her eyes in the lab?
Safety goggles
A high pressure zone is also called an __________.
anticyclone
What is weather?
The atmosphere on a particular day
True or false: During the night, the temperature of the land is warmer than the temperature of the water.
False
What is a flood?
an overflowing of a large amount of water
What machine do you use to look at cells?
What tool do we use to measure atmospheric pressure?
Barometer
What is climate?
A series of weather events over many years
Why are hurricanes becoming more powerful?
Because of climate change, the air temperature rises. As a result, there is low pressure, which creates more energy and stronger winds. The air temperature rise causes more water to evaporate and there to be more rain.
What is a downpour?
a heavy rainfall
What is the name of the containers that scientists use in a lab?
How does wind form?
During the day, air above land heats up faster than air above water. Warm air above land expands and rises, and heavier, cooler air rushes in to take its place, creating wind. At night, the winds are reversed because air cools more rapidly over land than it does over water
What is the 30/30/30/ rule?
Three things that increase the chance of a wildfire:
Temperature > 30
Humidity < 30%
Wind speed > 30 km/hr
What is an isobar?
a line on a map that shows a meteorologist what the pressure is at the surface of the earth
What is a gust?
A sudden, brief increase in the speed of wind
Define an experiment.
a scientific procedure, especially in a laboratory, performed to determine something
What is the unit we use to measure atmospheric pressure?
pascal (Pa) or millibars
List three things that are needed for clouds to form.
1. There must be water vapour in the air.
2. The temperature must cool so the water vapour condenses.
3. There must be very small particles (dust) in the air so the water molecules can attach to them when the condense.
True or false: In the northern hemisphere, the air masses in storms rotate clockwise.
False
What is a storm surge?
The rise in sea level due to a storm
What is it called when you cut open an animal to learn about its anatomy?
a dissection
