Lesson 1
Pilots must adjust their barometers for these two specific variables because they both cause air pressure to change.
Temperature and humidity?
Because of Earth's shape, sunlight is the least concentrated at these two specific locations, making the air there denser and higher in pressure.
The poles
While weather changes day to day, this term refers to the average conditions of a region, including its temperature, rainfall, humidity, and wind.
Climate
This is the specific term for the boundary where two different air masses meet, often causing a change in the weather.
Front
This is the specific name for a scientist who specializes in studying Earth's atmosphere to predict the weather.
Meteorologist
Atmospheric pressure is generally higher on a dry day because air pressure does this as the amount of water vapor (humidity) increases.
It decreases
When air is heated, it becomes less dense and rises; as it cools, it performs this action to create a continuous air flow.
It sinks (or move beneath warmer air)?
Because ocean water moderates temperature, the highs over beaches in summer and the lows in winter stay within this specific type of range compared to inland areas.
Narrow range? (Or "not as high and not as low")
According to scientific theory, lightning is a discharge of electricity that builds up when these two types of particles rub against each other inside a thunderhead.
Ice and rain
This high-speed wind current is caused by temperature differences between air masses and generally pushes them across the country from west to east.
Jet Stream
When air is cooled, the gases slow down and move closer together, causing the air pressure to do this.
It increases
During the day, air moves from the ocean toward the land because the air over the water has this specific level of pressure compared to the air over the land.
What is higher pressure?
During the process of evaporation, heat is taken in by water, but during this opposite process, heat is released back into the atmosphere.
What is condensation?
Hurricanes form near the equator because the water is warm and evaporates, and this specific type of air has a lower pressure that pulls the storm together.
Humid air
In a low pressure system, air rushes inward toward the center, causing the winds to turn in this specific direction.
Counterclockwise
As this measurement of the space an object occupies increases for a container, the air pressure inside of it decreases.
Volume
This heat transfer process occurs in liquids and gases—but not solids—because their particles are free to move around.
This is convection
This is an ongoing movement of ocean water that transfers heat from one place to another, directly affecting the weather of nearby land.
Ocean current
Hurricanes and tornadoes are both considered types of cyclones because they both feature spinning winds and this specific type of center.
Low-pressure closure
In a high pressure system, air moves outward in all directions, which causes the winds to rotate in this direction.
Clockwise
This is the height above Earth's surface measured from sea level, which causes atmospheric pressure to decrease as it gets higher.
Altitude
This is the specific direction air always moves between areas of different pressure to create local and global winds.
High to low pressure?
During this event every 2–7 years, a cold current sinks and fails to reach the surface, causing air pressure to fall and bringing heavy rains and storms.
El Niño
This specific type of fog forms when warm, humid air flows over cold ground or water, making it difficult to see.
Advection fog
On a weather map, a blue line with triangles and a red line with half-circles represent these boundaries that tell you what the weather will be like in the future.
