15.1 Earth’s Atmosphere Worksheet Answers – Hints: Follow the prompts to enter the simulation. Answer the questions and clues in the orange box.

It is different from rolling down the windows so that not all the heat will get into the car, which will cool the car.

## 15.1 Earth’s Atmosphere Worksheet Answers

Gizmo Like a car window heater, greenhouse gases play an important role in the global climate. Without heat-trapping gases in Earth’s atmosphere, Earth would be a desert as cold as Mars (average temperature -55 °C, or -67 °F). Most of the gas and earth can be a fiery planet like Venus (average temperature 450 ° C, or 850 ° F).

#### Solved Earth’s Atmospheric Pressure Below Is Information

Reset Gizmo: Click Reset ( ). Set the simulation speed to slow. Make sure the gas level is 10%.

Glass If there is no glass, the warm air will mix with the cold air outside and the result will be the same temperature inside and outside the greenhouse.

In Earth’s atmosphere, the gas is transparent to light but absorbs heat from the Earth’s surface. Some of this heat is returned to Earth. If there is no gas, all heat will be lost to space.

1. Click Play ( ) and look at the BAR CHAR T page, the temperature will go up and down every day, but try it.

2. Now set the gas to 100% and let the simulation run for a while. How about max1’s Placeholder The Atmosphere 15 CHAPTER I opening page, but maybe we can copy the SE chapter opening page using the same font and color (and maybe the Ch 14 symbol?)

In 1952, more than 4,000 people died in London during the “deadly fog”. In 2003, the City of London began charging people who visited the city each week. Since the program began, traffic in London has fallen by 30%, but there is no evidence that air quality has improved. Talk about it What are the advantages and disadvantages of jam filling program?

The air we breathe and all the weather we see is less than 1% of the Earth’s atmosphere.

Lesson 15.1 Characteristics of Earth’s atmosphere Composition: 78% nitrogen, 21% oxygen, and 1% other gases Temperature: Varies by location Pressure: In general, atmospheric pressure decreases with altitude; It can be measured with a barometer. Barometer

#### Humans Affect Climate

Humidity The reduction of water vapor in the air to the maximum amount that one air can hold at one temperature affects the temperature and location; In general, warmer air holds more water. When the air cools, water vapor can condense into water or ice. Water vapor can only condense on surfaces, such as thin films or dust particles. Frostbite on leaves

Lesson 15.1 Earth’s Climate Did You Know? The cold areas and the mesosphere are cold, but the upper thermosphere can be hotter than 1500 ° C. Temperature: 0-11 km; Air movement, Stratosphere: 11-50 km; Ozone layer absorbs and emits UV rays Mesosphere: 50-80 km; meteoroids burn Thermosphere: 80+ km; Insects produce the aurora borealis

Lesson 15.1 Atmospheric Heat Transfer in the Troposphere Radiation: the transfer of energy through the atmosphere, such as from the Sun to the Earth’s atmosphere Heat: the direct transfer of heat between two objects in contact Convection: the transfer of heat through the movement of water (water). or gas) inside

Lesson 15.1 Current Conditions in the Earth’s Climate Warm air is not stronger than strong air. When the air near the surface heats up, it rises; As it rises, it cools down and sinks. Rising and falling water creates currents. It causes air and heat to move out of the atmosphere

## Section 1.1 What Is Earth Science? This Section Explains What Earth Science Is And What Earth Scientists Study.

Front and East Air Flow: Large air bodies with similar properties Front: Boundary between air masses of different properties Warm fronts Warm, moist air pushes cold, dry air. Therefore, cold air can cause light fog. The point where cold, dry air pushes warm, moist air can lead to heavy rain.

Lesson 15.2 Natural Sources of Air Pollution: Airborne dust, particles from volcanic eruptions, smoke and ash from fires Human sources: Most come directly or indirectly from burning gasoline. Do you know? People can increase the risk of air pollution. For example, by cutting down trees, people expose soil, which can dry out and cause dust storms when blown by the wind. A dust storm near an American farm in the 1930s

Lesson 15.2 Types of Environmental Pollution Primary Type of Air Pollution: Released directly into the atmosphere. Example: Soot Secondary air pollution: it is formed when the primary pollution reacts chemically with other substances; Example: Sulfuric acid

Lesson 15.2 Air Pollution How Air Pollution Affects Your Health Lung inflammation and respiratory diseases, such as asthma Carbon monoxide interfere with the body’s ability to use oxygen. Small amounts of some air pollutants, such as benzene or soot, can cause cancer.

Lesson 15.2 Air pollution Smog is a dangerous form of air pollution that occurs in cities. Industrial smog (soot, sulfur and moisture) comes from industrial sources. Photochemical smog mostly tropospheric ozone when the first pollution from the vehicle reacts with sunlight.

Lesson 15.2 Air Pollution Did You Know? Climate change is creating London’s “killer smog”. In theory, the air around the planet warms and rises, taking pollutants with it. When warm air sits on top of cold air, it pulls polluted air closer to the Earth’s surface.

Acid storage Sulfur dioxide and nitrogen oxides can react with water, oxygen, and other chemicals to produce acid. The acid falls as sediment or dissolves in precipitation, lowering the pH of rain and snow. Acid base destroys forests and lakes and destroys human infrastructure. Do you know? Precipitation is acidic (pH 5.6), but in some parts of the United States the pH of acidic precipitation is less than 4.

Since the implementation of the Clean Air Act in 1963, emissions of the worst in the United States have decreased by 57 percent.

### Earth’s Atmosphere Worksheets

The Clean Air Act was enacted in 1963 to improve air quality to protect human health and the environment; It has been revised several times to limit emissions, set air standards, establish legal frameworks for breaking industrial standards, and provide funding for air pollution control.

Lesson 15.3 Controlling Air Pollution The great success of the air conditioner, which has been in all cars since 1975, has reduced car emissions. Lead is removed from gasoline. Factories and power plants reduce emissions by using scrubbers, which remove or replace chemicals before they leave the factory floor. Do you know? Removing lead from gasoline has reduced lead emissions by 99 percent since 1973.

Ozone Hole Ozone is a pollutant in the troposphere, but in the stratosphere it forms a protective barrier against UV radiation. Chemicals called chlorofluorocarbons, found in everything from air cans to refrigerators, destroy ozone, creating an “ozone hole” over Antarctica. The ozone hole allows more UV light to reach the Earth’s surface, potentially increasing the risk of skin cancer. Aerosol can be sprayed

Lesson 15.3 Controlling Ozone Layer Air Pollution The Montreal Protocol is an international agreement signed in 1987 that has reduced the production of CFCs by 95 percent since the 1980s. Ozone levels in the stratosphere have stabilized, and the hole ozone will begin to disappear. Ozone hole 1979 Ozone hole 2000
