This instrument measures air temperature in Fahrenheit or Celcius.
What is a Thermometer?
The weather describes ______________________.
What are the conditions of the atmosphere at a particular time and place?
True or false: Air is matter even though we cannot see it.
What is True?
This happens to the space available to air when a sealed syringe's plunger is pushed down.
What is decreases?
This atmospheric layer is furthest to Earth's surface
What is the Exosphere?
This unit of measure tells you the humidity in a weather report.
What is Percent?
True or false: One weather observation is enough to identify a long-term pattern.
What is False?
For something to be considered matter, it must have these two properties.
What are have mass and take up space?
True or false: Air particles get smaller when air is compressed.
What is False?
This atmospheric layer extends approximately 12–50 km above Earth's surface
What is the Stratosphere?
A meteorologist measures air pressure. Name the instrument and unit.
What is a barometer and millibars?
Meteorologists record weather conditions many times do these two things
What are identify patterns and predict weather?
This experiment could provide evidence that air has mass
What is weighing a balloon before and after filling it with air?
This happens to the particles when air is compressed.
What is move closer together?
In the Troposphere and Mesosphere, this happens to temperature as altitude increases.
What is decreases?
A speed sensor and weather vane can be used to measure these two weather factors.
What is wind speed and direction?
These types of weather conditions stay similar over time.
What are stable weather conditions?
Trapped air occupies volume and resists when the plunger is pushed demonstrates what?
What is air takes up space?
It is harder to push the plunger of a sealed syringe farther down because of this.
What is compressed air pushes back against the plunger?
Weather only occurs in this layer of the atmosphere.
What is the troposphere?
Match all five weather conditions with their units: temperature, humidity, air pressure, wind speed, and wind direction.
°C or °F; humidity: %; pressure: mb; speed: km/h; direction: N, E, S, W
A scientist notices that air pressure falls before several rainy days. How could the scientist use this observation?
Compare repeated records and use the pattern as evidence when making future weather predictions
A student says air cannot be matter because it is invisible. Give two pieces of evidence to prove the student wrong.
An inflated balloon gains mass; trapped air in a syringe occupies space. Therefore air has mass and volume
Two particle models show compressed air. Model A has smaller particles; Model B has the same number of particles closer together. Which is correct and why?
Model B. Compression reduces the space between particles, not their size or number
A measurement is taken 100 km above Earth's surface. Identify the atmospheric layer, its approximate altitude range, and its temperature trend.
Thermosphere; approximately 80–700 km; temperature increases with altitude
