Make sure you have your textbook open to 15.3 today! Bell Ringer: 1) Please open your IAN to yesterday’s notes on greenhouse effect. 2) Review your key tech terms with the sheet in your blue tubs.

Essential Questions: 1) Differences between the Greenhouse Effect and Global Warming? 2) How Does the Earth Cool off?

The Greenhouse Effect and Life on Earth 6) The greenhouse effect: is Earth’s natural heating process. Increasing levels of greenhouse gases could cause global warming. Many scientists have become concerned about data that show that average global temperatures have increased in the past 100 years. 7) global warming: an increase in average global temperatures. 

Greenhouse Effect Basics Gases absorb the heat and act as a “blanket” to keep Earth warm. Some greenhouse gases: water, methane, carbon dioxide. The gases function like the glass walls and roof of a greenhouse, which allow solar energy to enter but prevent thermal energy from escaping. Greenhouse Effect Basics

Runaway Greenhouse Effect In your IAN, please copy!

The Greenhouse Effect Global Warming gases (CO2 and water vapor) absorb thermal energy and radiate it back to Earth a process that reminds us of an actual greenhouse an increase in average global temperatures greenhouse gases in the atmosphere https://www3.epa.gov/climatechange/kids/index.html VS.

Manmade Causes: Industry Deforestation Cars Fossil fuels Wars Heat/AC Arms race Nuclear waste Coal burning Electricity Land fills Acid rain

Global Warming Causes Natural: Volcanoes Solar flares Cycle Orbit Cows https://app.discoveryeducation.com/learn/videos/2E2EB8C5-65C5-4825-BAE9-4D5C2C283F43?hasLocalHost=false Forest fires Methane release in the arctic tundra

Final Research: You Decide! Question: Is Global Warming real? Is it a natural event or man made? Is it natural and people are making it worse? Bill Nye debate https://www.brainpop.com/science/earthsystem/climatechange/

Let’s Review! Explain research on 2 different points of view for Global Warming. 5 facts each. Try to answer the following questions: A. What is it? B. What is causing it? C. What will change (ocean levels, animal/plant life)? D. What might the temperature be in 100 years? E. What are manmade contributions? F. What are arguments for the ‘natural cycle’ side of it?

15.3 Global Winds and Local Winds Objectives: Explain the relationship between air pressure and wind direction. Describe global wind patterns. Explain the causes of local wind patterns. 15.3 Global Winds and Local Winds Copy into your closed notes!

Why Air Moves Wind-movement of air is caused by differences in air pressure Greater pressure difference= faster wind

Air Rises at the Equator and Sinks at the Poles Differences in air pressure are generally caused by unequal heating of the Earth. Equator Receives more direct solar energy Air is warmer and less dense Warm air rises and creates low pressure area Warm air flows to poles Convection Currents!

Air Rises at the Equator and Air Sinks at the Poles, cont’d Air is cooler and more dense Cold air sinks Creates high pressure area Cold air flows toward equator AIR will blow from H to L !!!

Pressure Belts Are Found Every 30 Degrees Pressure belts- bands of high pressure and low pressure found every 30 latitude. Sinking air causes areas of high pressure because sinking air presses down on the air beneath it.

PressureBelts

The Coriolis Effect Apparent curving of the path of winds and ocean currents due to the Earth’s rotation. North- winds going north curve east South- winds going south curve west Connection??

Global Winds Patterns of air circulation Named after the direction from which they blow Major global wind systems Polar easterlies Prevailing Westerlies Trade winds

Global winds

Polar Easterlies Poles to 60 latitude in both hemispheres Cold, dense air moves from poles to 60 Effect? Can bring cold air to US making snow and freezing weather

Prevailing Westerlies 30 and 60 latitude in both hemispheres Flow from west to east Effect? Can bring moist air to US making rain and snow

Trade Winds 30 latitude almost to equator in both hemispheres Due to Coriolis-curve to west in N. Hemisphere and east in S. Hemisphere Effect? Traders used winds to move from Europe to Americas.

Bell Ringer Day 2: In your IAN, please answer the following questions: Take out your closed notes for 15.3 Name& Describe 3 examples of global winds. Would there be winds if the Earth’s surface were the same temperature everywhere? Why?

Doldrums: located where the trade winds of the two hemispheres meet at the equator means “dull” or “sluggish” an area of Low Pressure

The Horse Latitudes 30 north and south latitude Very weak winds

Jet Stream: Atmospheric Conveyor Belts Narrow belts of high speed winds Blow in the upper troposphere and lower stratosphere Effect? Can affect movement of storms and airplane flights Cool Fact! Did you Know?

Local Winds Move short distances Blow from any direction Caused by temperature differences Sea breeze moves from sea to land Land breeze moves from land to sea

Sea Breeze

Land Breeze

Convection current

What effect does elevation have on winds?? How does wind blow? Wind will flow from high to low!!! What effect does elevation have on winds??

Mountain Breeze vs,. Valley Breeze

Wrapping it up: What role does the Sun play? Brainpop Wind Sun heats the land and water, changing temperatures Different heating causes density differences, causing wind! UNEQUAL HEATING CAUSES THE WIND! Local Winds eactivity Brainpop Wind
