Weather
Large body of air with similar temperature and moisture
Forms over specific regions (like oceans or deserts)
Takes on characteristics of the area where it forms
Air Masses
What is something you can’t see, but you can feel?
Water Vapor (humidity)
Which layer of the atmosphere has air that's breathable?
Troposphere
average
During the summer, large bodies of water absorb a lot of _______________.
Heat/Warmth
Air masses move based on wind patterns, Earth's Rotations, and _____________________.
Temperature Differences
Warm air produces what type of pressure?
Low Pressure
Is atmospheric pressure higher or lower near
the ground?
Higher
As latitiude increases temperature tend to be warmer or colder?
Colder
These are predictable winds at certain locations. Sailors have used these winds to sail for hundreds of years.
trade winds or prevailing winds
Name 2 things that happen when air masses meet.
They create weather fronts
They can cause precipitation
Temperature changes occur
Clouds often form
Air that is closer to the equator is ______________.
Warmer
Air has weight as ______________ pulls it down.
Gravity
At the______________, the temperatures are highest because these areas get more direct sunlight
Equator
Deep ocean currents also move heat around the planet and is known as what?
the global conveyor belt
Cold air pushes under warm air this is called a _________ front.
Cold
A ________ breeze is when the air moves from the sea to the land during the daytime.
Sea Breeze
There is less ___________ at higher altitudes.
Oxygen
Mountains can create a __________ ___________ in which warm/moist air rises up the side of the mountain near water.
Rain Shadow
When the wind blows over the surface of the ocean, it causes waves to form and the water at the surface to move. This is known as what?
Surface Currents
These instruments measure air pressure.
Barometers
This is the state of the atmosphere at a given time and place. It's affected by many different variables, including temperature, precipitation, wind, and air pressure.
Weather
At higher altitudes, the atmospheric pressure
__________________.
Decreases
Because earth is a sphere, this influences wind patterns, which influences how ocean currents move.
Coriolis Effect
Deep ocean currents happen because there are differences in seawater densities due to temperature and what else?
Salinity (salt content)
