A "dome" of water that sweeps across the coast where a hurricane lands is called a(n)
storm surge
100
On weather maps, a line with half circles indicates a
warm front
100
The region around a magnet where the magnetic force is exerted is known as its
magnetic field
100
What unit is used to measure force?
Newton (N)
200
Winds are caused by differences in
air pressure
200
If people are asked to evacuate during a hurricane watch, they are being asked to
leave the area temporarily.
200
When a warm air mass and a cold air mass meet and neither can move the other, the result is a(n)
stationary front
200
A glowing region in the atmosphere caused by charged particles from the sun is called a(n) _____________________.
aurora
200
The force that two surfaces exert on each other when they rub against each other is called ____________.
friction
300
The process by which gases hold heat in the atmosphere is called the
greenhouse effect
300
Local winds differ from global winds because they
are caused by unequal heating within a small area.
300
Earth's rotation makes global winds curve. This is called the
Coriolis effect
300
A cluster of billions of atoms that all have magnetic fields lined up in the same way is known as a
magnetic domain
300
The force of gravity on a person or object at the surface of the planet is called _____________.
weight
400
Heat from the sun reaches you by
radiation
400
Land breezes occur because
land cools off faster than water.
400
Cold, dry air affecting the northern United States in winter often comes from
continental polar air masses.
400
Streams of electrically charged particles flowing at high speeds from the sun make up the
solar wind
400
The friction that an object feels as it is falling through air is called _____________________.
air resistance
500
Convection takes place because
cold air is more dense than warm air.
500
Global winds generally
blow from specific directions over long distances.
500
What kind of weather would a continental tropical air mass that formed over northern Mexico bring to the southwestern United States?
hot/warm and dry
500
What is the region of Earth's magnetic field shaped by solar wind?
magnetosphere
