PART 1. WIND

CLASSWORK

ANSWERS

Page 8: CRCT Question

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

Page 12: CRCT Question

Polar Easterlies Westerlies Trade Winds

Poles to 60˚Moist air United States 30˚ to 60˚Cold air

More dense=sinkEarly Sailors 30˚ to equator

Page 13: CRCT Question

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

Page 14: CRCT Question

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

HERE STUDY GUIDE

Page 17: CRCT Question

1. WHAT ARE THE TWO MOST ABUNDANT ELEMENTS IN THE ATMOSPHERE

(PERCENTAGE)?

1. Nitrogen – 78%2. Oxygen – 21%

Page 18: CRCT Question

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

Page 19: CRCT Question

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

Page 20: CRCT Question

4. LIST THE LAYERS OF THE ATMOSPHERE FROM EARTH’S SURFACE TO SPACE.

Troposphere – Stratosphere – Mesosphere - Thermosphere

Page 21: CRCT Question

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

Page 22: CRCT Question
Page 23: CRCT Question

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

Page 24: CRCT Question
Page 25: CRCT Question

7. WHERE DOES AIR POLLUTION COME FROM?

The burning of fossil fuelsCauses: Smog and Acid rain

Page 26: CRCT Question

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

Page 27: CRCT Question

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

Page 28: CRCT Question

10. WHAT CAUSES WIND?

Difference in air pressure due to the unequal heating of the Earth’s

surface

Page 29: CRCT Question

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.

Page 30: CRCT Question

12. WHAT IS THE FORMULA FOR DENSITY?

Density = mass/volume

Page 31: CRCT Question

13. WHAT IS THE DIFFERENCE BETWEEN A BAROMETER AND

AN ANEMOMETER?

Barometer measures air pressure

Anemometer measure wind speed

Page 32: CRCT Question

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)

Page 33: CRCT Question
Page 34: CRCT Question

15. HOW ARE THE LAYERS OF THE ATMOSPHERE

CLASSIFIED?By changes in temperature

Page 35: CRCT Question

16. WHAT IS THE DIFFERENCE BETWEEN VOLUME AND MASS?

Volume is the amount of space something occupies

Mass amount of matter in an object

Page 36: CRCT Question

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

Page 37: CRCT Question

18. HOW DOES PRESSURE EFFECT

DENSITY?Greater pressure =higher

density=sink

Lower Pressure=lower desnity=rise

Page 38: CRCT Question

19. WHAT HAPPENS TO AIR PRESSURE AS YOU INCREASE

WITH ALTITUDE?

It decreases

The most pressure is at the surface!

Page 39: CRCT Question

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

Page 40: CRCT Question

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
