17 & 19 survey

How does weather and climate differ ?
Weather is the events occuring now and climate is weather that occurs years long
List the items found in the atmosphere along with its percentages.
Nitrogen-78% Oxygen-21% other gases-2%
Explain the difference between primary pollutants and secondary pollutants.
Primary pollutant- pollutants that enter the atmosphere from a visible, secondary pollutant-pollutants that enter the atmosphere through other methods
Where is ozone found ? What is its purpose ?
Ozone is in the stratosphere-purpose is to lock in the heat
What happens to pressure and temperature as you increase in altitude ?
Pressure and temperature decreases
Explain the differences between rotation and revolution.
Rotation spinning on its axis (day and night) and revolution is the revolving around a body (365.25 days)
List the layers of the atmosphere in order from the earth’s surface upward.
Explain the difference between solstice and equinox.
Solstice-winter(shorter day,longer nights),summer(longer day,shorter night)
Differentiate between the three ways heat is transferred.
What happens to solar radiation ?
50% is absorbed on earth,20% is absorbed in clouds,30% is reflected off clouds
Explain the difference between reflection and scattering.
Reflection- rays bouncing off clouds,scattering-rays are moving in all directions
List the ways temperature can vary on Earth.
Land heats up quick and cools quickly,water heats up slowly and cools slowly,as you move up a mountain temperature cools off,as you move up in altitude temperatures cool down,clouds help lock in the temperatures at night and reflect off radiation during the day
How do temperatures vary from land to sea ?
Land heats up quick and cools quickly,water heats up slowly and cools slowly
What is albedo and how does it change from day and night ?
Clouds help lock in temperature at night and reflect off radiation during the day
How does altitude affect temperatures ?
As you move up in altitude temperatures cool down
Explain air pressure.What unit do we measure pressure ?
Air pressure in a force exerted in all directions,measured in millibars
What is a barometer ? List the two types
Tool measuring air pressure,mercury and aneroid
How does wind form ?
Sun and pressure differences
Winds move from a ____to____pressure systems
High & Low
Describe an isobar: What happens if they are closely spaced together ? Far apart ?
Isobars are lines of equal pressure,closely spaced lines are low pressure and widely spaced lines are high pressure
Describe a high and low pressure system.Include weather conditions too.
High pressure system-good weather(anti-cyclone moving clockwise),low pressure-stormy weather(cyclone-counterclockwise)
What direction does the Coriolis effect spin the Northern Hemisphere ?
Conter clock wise
How does friction affect wind ?
Slows wind down
What direction does the jet stream travel in the Northern Hemisphere ?
West to East
Where do you find friction at its strongest point ?
In mountain areas
Describe the movement of cyclones and anticyclones.
cyclones move conterclockwise,anticyclones move clockwise
Describe the movement of trade winds,westerlies and polar easterlies
trade winds move east to west,westerlies-move west to east,polar easterlies move east to west
Explain the differences between land and sea breezes
Land breezes occur at night where wind moves from land to sea,sea breezes occur during the day where wind moves from the sea to land
What instrument is used to determine the direction of the wind ?
Wind vane
How do you classify the direction of the wind ?
By the direction it came from
What instrument is used to measure the speed of wind ?
