How do winds influence temperature?
the movement of air cools things down
Winds carry energy in the form of heat around the Earth
by the way they are named
by transfering radiation from the sun to the ground
What are some factors that affect visibility?
fog, rain, and pollution
air pressure
temperature and latitude
eye color
1. Which ocean current directly affects the weather along the southernmost coast of the eastern United States?
The Canary Stream
The Humboldt Current
The Gulf Stream
The polar jet stream
What is a jet stream?
the preferred path of planes in the northern hemisphere
a body of air with similar temperatures and humidity throughout
a part of the atmosphere that filters out ozone
a narrow band of strong winds that blow in the upper region of the atmosphere
1. Air typically moves from areas of
mountains to valleys
high pressure to low pressure
north to south
the ground to the upper atmosphere
1. How do surface currents affect temperature?
they will make conditions more dry and arid
they do not actually change temperature
they will cause more reflection of the suns rays
they can change the temperature of the air above the surface current
What is humidity?
how hot it is outside
a measure of the amount of condensation
The point in which the atmospheric pressure is conducive for a storm
the amount of water vapor in the air
How are humidity and water vapor tied together?
The higher the humidity %, the more water vapor there is in the air
The lower the humidity %, the more water vapor there is in the air
humidity makes water vaport disappear
both are required to create a drought
What happens in a high pressure system?
As the air sinks, it gets warmer and absorbs moisture. Water droplets evaporate, relative humidity decreases, and clouds often disappear.
as the air rises, it gets cooler and condenses, causing clouds and light rain
air molecules begin to spread apart, causing temperatures to decrease
conditions become right for a tornado or hurricane
What happens to the rising air mass in a low pressure system?
it sinks and absorbs clouds and moisture
air molecules clump together and temperatures increase
It cools and forms clouds and rain.
the weather will be cool and clear
What is the difference between weather and climate?
weather describes only one time and place, while climate describes the weather conditions in an area over a long period of time
climate describes only one time and place, while weather describes the weather conditions in an area over a long period of time
it will depend on whether or not you are in the southern or northern hemisphere
Climate can only happen during the winter months
What is the dew point?
It is the temperature at which clouds will begin to clear up
It is the amount of air pressure needed for a storm to occur
It is the temperature at which condensation will begin and clouds start to form
It is another form of transpiration
What is weathering?
studying atmospheric conditions over a long period of time
The breaking of rocks into smaller pieces
when rocks and sediment are carried away
when materials are dropped in a new area
How do caves form?
when acids in groundwater weather limestone rocks underground
when enough animals dig a burrow in the same area
when a landslide creates a large hole in the ground
When the rock in a mountain weakens and falls in
Which part of physical weathering changes sand dunes?
water
pressure changes
Wind
animal action
How are glaciers formed?
when enough sea water freezes and it becomes larger than an iceberg
the large amount of hail that builds up at the poles build these
The snow builds up, and its weight compresses the snow below into ice
the tides become frozen at both poles during the winter months
What is the difference between a delta and an alluvial fan?
deltas form in the western hemisphere, alluvial fans form in the eastern hemisphere
deltas are a natural phenomenon, while alluvial fans are man made
The alluvial fan is in the water, the delta on dry land
The alluvial fan is on dry land, the delta is in the water
What is a landslide?
when dirt and water take over a hillside and go into the streets
A mass of rocks sliding together down a slope
when an enire portion of the mountains slides off in one piece
this is something that can happen before a volcanic eruption
What are the main examples of physical weathering?
oxidation, groundwater acid, and lichen and moss
temperature changes, pressure changes, plant and animal actions, water, wind, and gravity
the study of atmospheric conditions and daily weather
the way in which human activity can have an effect on the weather
1. How does chemical weathering effect rocks?
it will break them into smaller pieces
it will make them smoother and shinier
it can change their color, wear them down, make them softer
it will cause them to be more vulnerable to landslides
How does oxidation affect rocks?
it changes their color
it makes them weigh less
it breaks them into smaller pieces
the rocks will now have a weird smell
Describe how wind moves sediment.
Changes in air pressure cause the sediment to heat up and the molecules to move faster within it
It picks it up and carries it. It will deposit things as it slows down, dropping the heaviest particles first, and the lightest last. The more trees, rocks, and vegetation there is around, the more obstacles that will stop the path of the wind
It picks it up and carries it. It will deposit things all along the way, dropping the smallest particles first, and theheaviest last. The more trees, rocks, and vegetation there is around, the more obstacles that will give strength to the path of the wind
Wind must have water to help it move sediment, it is not strong enough on its own
How does a sinkhole form?
When the roof of an underground cave is no longer supported by water, the weight on top of it will cause the cave collapse
When the roof of an underground cave is eaten away by lichen, it will get weak and collapse
certain types of animals like prairie dogs and gophers cause enough movement underground to cause these collapses
oxidation of the rock underground will weaken it and cause the cave roof to collapse
