Exciting slide huh?

Weather:The condition of the atmosphere, or the air that
surrounds the Earth, at a certain place and time.

Temperature:The measure of how hot or cold something is.

Humidity:A measure of how much moisture is in the air.
Water Vapor:Water in the form of a gas.
Humidity @ BrainPop
Weather and ClimateWeather and Climate
Q: How does the air feel on a hot humid day? Why?
A: On a hot, humid day, the air feels damp and sticky because it contains so much moisture.
Bonus Definitions:Bonus Definitions:
Absolute Humidity:How much water is actually in the air.
Relative Humidity:The relative humidity tells how much water the air is holding compared to how much it could hold at
a certain temperature.
Weather and ClimateWeather and ClimateAir Pressure:
The weight of the air around Earth pressing down on Earth's surface.
How Does Air Pressure Cause Ear Popping?“The main cause of air pressure-related ear popping is an
imbalance between the pressure within the ear and the pressure outside of the ear. Anytime there is a huge disparity between the two air pressures, the tympanic membrane, or eardrum, expands or contracts in an effort to help equalize
the pressures. This contraction or expansion causes a popping or crackling sound in the ears.”

Q: Does cold or warm air have more air pressure? Why?
A: Cold air tends to have higher air pressure than warm air because it weighs more.
Have you ever heard that Warm Air rises?

Local Wind:Affects weather in only a small region.
Weather and ClimateWeather and Climate
Sea Breeze:Warmer air over the land is pushed up by cooler
air moving in from over the water.
Land Breeze:Warmer air over the water is pushed up by cooler
air moving out from over the land.
Wind @ BrainPop
Weather and ClimateWeather and Climate
Prevailing Winds:A pattern of moving air over large parts of Earth.
Bonus:●Prevailing Winds (global winds) are caused by
the uneven heating of large areas of Earth's surface caused by Earth's rotation, or spin.
●Prevailing Winds blow from the same general direction.
●In the United States winds called the Prevailing Westerlies blow from west to east.
