Air pressure ____________ as elevation increases.
Air pressure decreases as elevation increases.
Air pressure changes with elevation.
What is air pressure decreases as elevation increases?
Weather occurs here
What is the troposphere
The physical process that turns a liquid into a gas when water particles gain enough energy to move into the atmosphere as water vapor.
What is evaporation?
Differences between weather and climate
Weather is the condition of the atmosphere at a specific time and location, while climate is the average weather in a region over a long period of time.
Land heats up ________ than water, making the air over land _______ dense than the air over water.
Land heats up faster than water, making the air over land less dense than the air over water.
Denser air flows toward less-dense air creating what?
What is a convection current?
The angle at which the Sun's rays strike a location on Earth affects the temperature, with the equator being warment and temperatures cooling as you move north and or south.
What is the Sun's angle?
This occurs when water-vapor particles in the air come in contact with cooler surface, transferring energy and transforming into liquid water.
What is condensation?
Actions that contribute to climate change
What is driving more cars, creating more pastures for cows, burning more fossil fuels, and buying foods produced in large quantities from distant locations?
Air has ________ and takes up _________.
What is air has mass and takes up space.
The transfer of energy, such as heat or electricity, through direct contact between substances.
What is conduction?
Nitrogen, Oxygen, Argon, Carbon Dioxide, Water Vapor, ect.
What are gases that make up the Troposphere
When plants give off water vapor into the atmosphere.
What is transpiration?
Some environmentally conscious questions might be...
How much electricity does an air conditioner use per hour at different temperatures?
How many homes use natural gas vs electricity for heating?
How many months do people use air conditioning and heating?
Compressed air pushes back with a force _____ to the force compressing it.
What is compressed air pushes back with a force equal to the force compressing it?
Global convection currents in the atmosphere and the rotation of Earth (Coriolus Effect) influence this.
What are prevailing winds?
Will you find air in an empty jar with the lid on?
Yes, Air takes up space.
You are an engineer who designed a new grocery bag that keeps frozen foods frozen on the trip home. What material below would be the best insulator?
What is Styrofoam and or cardboard?
Some safety measures for tornado-prone areas...
What is having a safe, underground room or basement, a town siren for warnings, and practicing drills in schools and homes?
The more dense particles are, the ______ __________ it has.
The more dense particles are, the more pressure it has.
The movement of heat-driven fluids or gases resulting from differences in temperature. Hint: current
What is a convection current?
What happens when you release the plunger of a syringe with air in it?
The plunger will move back to where it started.
10. You build a pressure-indicator system like the one you see in the illustration (above) at sea level. If you take the device to the top of a mountain 4,000 m high, what change in the system would you see (if you did NOT squeeze the jar on the outside).
The water will go up in the straw because there is less air pressure inside the jar.
Actions that do NOT contribute to climate change...
What are using solar, hydro, and wind power energy, increasing home insulation, walking or biking instead of driving, and eating more vegetables and less meat?
