Layers of the Atmosphere
This is the furthest layer from Earth
Exosphere
What is air?
mixture of gases
Do daily weather records help identify patterns over time to make predictions about future weather events?
Yes
Do the size of air particles get smaller when they are compressed?
No, they stay the same size.
The degree of heat or cold present
Temperature
This layer has meteors in it
Mesosphere
In our investigation, we proved that air has ______.
mass
Do daily weather records explain the cause and effect for different weather events?
No
True or False. Air particles move faster when they are compressed.
True
Telling (or trying to tell) what will happen in the future
Prediction
This is the layer that contains the ozone layer
Stratosphere
Anything that takes up space and has mass is ______.
matter
Do daily weather records identify all the factors that contribute to a weather system?
No
True or False: Air particles get larger when they expand.
False, they stay the same size.
Water vapor or moisture in the air
Humidity
This layer is the hottest layer. There is no air in this layer.
Thermosphere
True or False. Air is matter
True
Do daily weather records help identify patterns of stable versus changing weather conditions?
yes
True or False: When air is expanded, it has lower air pressure.
True. The particles are farther apart, so the air pressure is lower.
A person who studies the causes of Earth's weather
Meteorologist
This is the layer that meteorologists study
Troposphere
Which investigation can we use to prove that air has mass?
1. Close off the end of a syringe and observe.
2. Use a scale to measure how much force air pushes back on the plunger with.
3. Use a scale to measure a balloon with and without air.
3. Use a scale to measure a balloon with and without air.
Name 3 weather factors that should be measured each day.
temperature, humidity, air pressure, wind speed, wind direction
True or False: When air is compressed, the particles move faster.
True. They bump into each other more often so they move faster.
The type of gas in the atmosphere that changes based on the environment
Variable Gas
