PART 1. WIND
CLASSWORK
ANSWERS
1. Land heats up faster than water.2. Warm air over land rises.3. Air over water moves to shore.4. Would occur during the day.5. Named a SEA breeze because it comes
from the sea.

1. Land cools off faster than water.2. Warm air over water rises. 3. Cool air from land takes its place.4. Would occur at night.5. Called a LAND breeze because the
wind is coming from the land.

CLOSER LOOK AT LOCAL WIND
When Air WARMS up When air heats up, it loses mass and
becomes less dense. The air becomes more spread out Because of this, warm air will rise
When Air COOLS down When air cools down, it gains mass and
becomes more dense The air will sink

Polar Easterlies Westerlies Trade Winds
Poles to 60˚Moist air United States 30˚ to 60˚Cold air
More dense=sinkEarly Sailors 30˚ to equator
GLOBAL OR LOCAL WIND ?????
1. Air over land is cooler and forms an area of high pressure. The cool air moves toward the ocean.
2. Polar Easterlies3. Generally moves over short distances4. Jet stream5. Caused by unequal heating over a large area6. Can blow from any direction7. Land breeze8. Is effected by the Coriolis Effect9. Caused by unequal heating within a small
area10.Valley breeze
11. The Doldrums12. Blows from a specific direction from day to
day13. Sea breeze14. Horse latitude15. Effected by local geographic features16. Westerlies17. Caused because the angle of the sun giving
the equator more direct sunlight18. Mountain breeze19. Trade winds20. During the day, air over the ocean is cooler
and forms an area of high pressure. The cool air flows to the land

Helpful hint: Atmosphere

PART 3. ATMOSP
HERE STUDY GUIDE
1. WHAT ARE THE TWO MOST ABUNDANT ELEMENTS IN THE ATMOSPHERE
(PERCENTAGE)?
1. Nitrogen – 78%2. Oxygen – 21%
2. WHAT IS WATER VAPOR?
Water that is in a
gas form
source of water: vapor: evaporation from Earth’s surface This satellite image
shows the relative amounts of water vapor: Dark – low water, white
– high water vapor
3. WHAT IS AIR PRESSURE AND WHY DOES IT OCCUR?
Air has pressure because it has mass
Air pressure is the measure of the amount of force the air has
4. LIST THE LAYERS OF THE ATMOSPHERE FROM EARTH’S SURFACE TO SPACE.
Troposphere – Stratosphere – Mesosphere - Thermosphere
5. WHAT ARE GLOBAL WINDS AND GIVE THREE EXAMPLES?
Blow from a specific direction year round. Cover a large area Curve due to the Coriolis Effect Caused by the unequal heating of the earth’s
surface the equator gets more direct sunlight causing the
air to rise at the equator and sink at the poles.
Examples – trade winds, jet stream, westerlies, and easterlies
6. WHAT IS THE GREENHOUSE EFFECT?
The warming of the surface and lower atmosphere of Earth
Occurs when water vapor, carbon dioxide, and other gases absorb thermal energy from the sun and do not allow the heat to escape back into space. (Like a greenhouse)
There are Increasing levels of carbon dioxide due to the burning of fossil fuels
7. WHERE DOES AIR POLLUTION COME FROM?
The burning of fossil fuelsCauses: Smog and Acid rain
8. WHAT ARE LOCAL WINDS AND GIVE TWO EXAMPLES?
Local winds are wind that blow over short distances
Come from any direction Examples – sea and land breezes
9. WHAT IS THE CORIOLIS EFFECT?
The apparent curving of the path of a moving object from an otherwise straight path due to the Earth’s rotation.
Northern Hemisphere: clockwise Southern Hemisphere: counter-clockwise
10. WHAT CAUSES WIND?
Difference in air pressure due to the unequal heating of the Earth’s
surface
11. EXPLAIN THE DIFFERENCE BETWEEN LAND AND SEA
BREEZES.
Land Breeze Sea BreezeAt Night During the Day
Land cools faster than water
Land warms faster than water
Warm air over the water rises and cool air from the land replaces it.
Air over the land then rises and cool air from
sea replaces it.
12. WHAT IS THE FORMULA FOR DENSITY?
Density = mass/volume
13. WHAT IS THE DIFFERENCE BETWEEN A BAROMETER AND
AN ANEMOMETER?
Barometer measures air pressure
Anemometer measure wind speed
14. DEFINE RADIATION, CONDUCTION, AND CONVECTION. GIVE TWO EXAMPLES OF EACH.
Radiation- Doesn’t need a substance. Transfer of energy through electromagnetic waves (ex. – campfire, sun’s radiant energy)
Convection – transfer of energy through a fluid (gas or liquid) (ex. – oven, boiling water in a pot)
Conduction – transfer of energy through a material/solid (iron, stove)
15. HOW ARE THE LAYERS OF THE ATMOSPHERE
CLASSIFIED?By changes in temperature
16. WHAT IS THE DIFFERENCE BETWEEN VOLUME AND MASS?
Volume is the amount of space something occupies
Mass amount of matter in an object
17. EXPLAIN THE DIFFERENCE BETWEEN WARM AND COLD
AIR AND THEIR DENSITY.Warm air is less dense
than cold air
Warm air will create low pressure area and rise
Cold air will create high pressure areas and will replace warm air
18. HOW DOES PRESSURE EFFECT
DENSITY?Greater pressure =higher
density=sink
Lower Pressure=lower desnity=rise
19. WHAT HAPPENS TO AIR PRESSURE AS YOU INCREASE
WITH ALTITUDE?
It decreases
The most pressure is at the surface!
20. WHAT IS THE DIFFERENCE BETWEEN LOCAL AND GLOBAL
WINDS? Both are caused by unequal heating of Earth’s
surface. Local Wind Global Wind
Small area Large AreaAny direction Predictable patternsSea breeze Coriolis EffectLand breeze Equator getting more DIRECT
sunlight
Local wind blows in any direction over short distances and are caused by unequal heating in a small area. Global wind blow over long distances in predictable patterns and are effected by the Coriolis Effect. They are caused because the equator gets more direct sunlight and the air rises at the equator and sinks at the poles
