Module 8 wind Flashcards
What do the winds represent in the Bible?
God’s intervention or interaction with mankind
Biblical references indicate that God is omnipotent and His spirit is powerful.
What causes wind?
Differences in air pressure
Air flows from high to low pressure to balance the force.
What is the definition of wind?
The horizontal movement of air flowing parallel to the Earth’s surface.
How does atmospheric pressure affect wind?
As air density increases, air pressure increases, causing air to flow from high to low pressure.
What creates lower pressure in the atmosphere?
Warmer, moist air rising in convection currents.
What happens to wind speed when there is a greater pressure difference?
The air will move quickly, causing strong winds.
What is an onshore breeze?
A breeze created when cooler ocean air flows in to replace warm air rising over land.
What is an offshore breeze?
A breeze created when cold air over land blows toward the ocean, replacing warmer air above the ocean.
How is wind direction labeled?
By the direction from which it blows.
What instrument is used to measure wind direction?
A wind vane or weather vane.
What does a wind vane indicate?
The direction from which the wind is coming.
What instrument measures wind speed?
An anemometer.
How does an anemometer work?
It rotates in the wind and translates the speed of rotation to a speed in miles per hour.
Fill in the blank: A wind coming from the northeast is called a _______.
northeast wind.
True or False: A wind vane points in the direction the wind is moving.
False.
What happens to wind on a warm summer day with uniform temperatures?
There will be very little wind.
What phenomenon causes convection currents in the atmosphere?
Unequal heating of the Earth’s atmosphere.
What role does the ocean play in creating breezes?
Water holds heat longer than land, affecting air temperature and pressure.
How does the pressure difference affect wind during the day?
Cooler air flows in to replace rising warm air, creating breezes.
What does the arrow on a wind vane indicate?
The direction from which the wind is coming.
