First, view the effects of heat-trapping pollution on Earth’s temperature in 1750, the current year, and 2050. Your goal is to help decision-makers see how as the blanket of pollution becomes thicker, more heat is trapped, which causes the average global temperature to rise. In the simulation yellow photons (sunlight) are entering the atmosphere. Red photons (heat) are being released from the Earth’s surface. Some red photons escape Earth’s atmosphere, but others are trapped by the blanket of greenhouse gases.

Complete the following steps:
1. Look for sources of greenhouse gases shown in the simulation in 1750. Then look for sources visible in the present and in 2050, noting how they change and what happens to the thickness of the blanket of heat-trapping gases.

2. Note the impacts of heat-trapping pollution on Earth’s temperature in each year. Note how many red photons are visible on the screen, the speed of temperature increase, and the final temperature.

Part 2
Click on the microscope icon (on the right), which allows you to “zoom into” the blanket and view the action of the top three heat-trapping pollutants. Complete the following steps:

1. Select CO2. Observe how it responds to the sun’s heat (red photons). What percent of red photons is it affected by (does it trap)? Repeat this exercise for CH4 and N2O.

2. Note of which molecules seem to be most and least frequently affected by infrared photons. The more powerful a greenhouse gas is, the more frequently it is affected.

Once you have completed the above steps, use your findings and the course’s readings to complete the lab questions below.

1. Identify natural and human-made causes of climate change visible in the computer simulation. According to the computer model, how have

What Are The Various Ways That Heat Can Be Transported In The Atmosphere

1. Describe and give examples of the various ways that heat can be transported in the atmosphere. Heat can be transported into the atmosphere in many ways. Three of those ways are radiation, conduction and convection. In radiation, heat from the ground moves up into the lower atmosphere heating the air. During conduction, heat moves from areas of higher heat to areas of lower heat during contact. When particles become heated, they move faster and “bump” into particles around them, thus transferring…

surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases. Solar radiation at the frequencies of visible light largely passes through the atmosphere to warm the planetary surface, which then emits this energy at the lower frequencies of infrared thermal radiation. Infrared radiation is absorbed by greenhouse gases, which in turn re-radiate much of the energy to the surface and lower atmosphere. The mechanism is…

Essay on atmosphere evolution of rocky planets

Atmosphere Evolution on Rocky Planets Atmosphere can be defined as a gaseous compound layer surrounding a large body mass suspended by means of gravity and centrifugal force caused by rotation [1]. Atmospheres of planets have not always been the same, its evolution comprised of complex development across million years of geologic time affected by various changes of variables inside and outside its planet [2]. Of the interest of this essay is the atmospheric evolution of a rocky planet. Rocky planet…

Argumentative Essay On Global Warming

come to mind when hearing climate change is global warming, but there is a difference. The definition of global warming is the increase of Earth’s surface temperature due to greenhouse gases while climate changes definition is a long term change in Earth’s climate. Therefore, global warming is a part of climate change because increasing earth's surface temperature can have an effect in the long run, hence, there is a correlation. Although the idea of global warming is typically thought out as the human…

Essay about Global Warming

ozone layer Introduction: The ozone layer is a layer in the earth's atmosphere containing relatively high concentrations of ozone. Global warming is climate change that causes an increase in the average temperature of the lower atmosphere. I believe there is a relationship between ozone layer and global warming. The following are some reasons there is a relationship between global warming, damage of the ozone layer and the temperature increase on earth. Causing A. the thinning of ozone layer…

Essay on Global Warming

of the earth. They have warned that the earth’s temperature has changed a lot and has affected many living and non living things. Some believe that a dramatically dangerous warming is taking place in the overall global climate, a problem that is referred to as “global warming “. Is Global Warming real ? There is evidence of global warming all around us. Global warming is defined as an increased in the average temperature of the Earth’s atmosphere. The process of Global Warming works by…

Geography-Land, Atmosphere and Oceans Essay

the BIOSPHERE. ATMOSPHERE The atmosphere is a layer of gas surrounding the Earth that is some 700 km (400 miles) thick. It is made up of nitrogen (78 per cent) and oxygen (21 per cent), plus traces of other gases. Tiny droplets of water vapour form the clouds we see. OCEANS Oceans cover 70.8 per cent of the Earth’s surface, to an average depth of 3.5 km (2 miles). The hydrosphere (watery zone) also includes freshwater rivers and lakes, but these make up less than 1 per cent of Earth’s water. LAND Dry…

environment is made up of four components, the lithosphere, biosphere, hydrosphere and atmosphere. The atmosphere is one component that has many intricate features and characteristics that affect the rest of the Biophysical environment. The way these components interact with each other determines how the local and global environments function. Components There are four components of the biophysical environment. The atmosphere is the gaseous layer that surrounds the earth. The biosphere is the part of the…

Global Warming Essay

The atmosphere is a mixture of different gases that surrounds the Earth. What is damaging the Earth’s atmosphere? What can be done to help save the atmosphere? There are many contributing factors damaging the atmosphere. There are many ways to save the Earth’s atmosphere. The Earth’s atmosphere is made up of many gases. Nitrogen makes up more than three-quarters of the atmosphere, with oxygen the other quarter. There is Argon and Carbon Dioxide that make up less than a half percent. Water…

Why There Is Global Warming Essay

media explain the high temperatures the earth has experienced in past years when there were far fewer people? Let us look back in the world's history: for example, between roughly 900AD and 1350AD the temperatures were much higher than now. And, back then there were fewer people, no cars, no electric utilities, and no factories, etc. So what caused the earth's heat? Could it be a natural occurrence? The temperature graph at the bottom of this article shows the temperatures of the earth before Christ…
