Phet colorado greenhouse simulation
The PHET Colorado Greenhouse Simulation is a valuable tool for understanding the science behind the greenhouse effect. The greenhouse effect is a natural process that occurs when gases in the Earth's atmosphere, such as carbon dioxide and water vapor, trap heat from the sun and warm the Earth's surface. This process is important for maintaining the Earth's temperature and supporting life on the planet. However, human activities, such as the burning of fossil fuels and deforestation, have led to an increase in atmospheric greenhouse gases, which has contributed to global warming and climate change.
The PHET Colorado Greenhouse Simulation allows users to explore the greenhouse effect in a virtual environment. Through the simulation, users can adjust various factors that influence the Earth's temperature, such as the amount of greenhouse gases in the atmosphere, the level of solar insolation, and the reflectivity of the Earth's surface. By manipulating these factors, users can observe how the Earth's temperature changes in response and understand the mechanisms behind the greenhouse effect.
One of the benefits of the PHET Colorado Greenhouse Simulation is that it allows users to see the consequences of increasing greenhouse gas levels in the atmosphere. As users increase the amount of greenhouse gases in the simulation, they can see how the Earth's temperature rises in response. This helps users understand the link between greenhouse gases and global warming and the importance of reducing our carbon footprint to mitigate climate change.
Another feature of the PHET Colorado Greenhouse Simulation is the ability to explore the role of other factors that influence the Earth's temperature. For example, users can adjust the level of solar insolation, or the amount of solar energy that reaches the Earth's surface, to see how it affects the Earth's temperature. They can also adjust the reflectivity of the Earth's surface, or albedo, to see how it impacts the amount of solar energy that is reflected back into space. These features help users understand the complex interplay of factors that influence the Earth's temperature and the importance of considering all of these factors when studying climate change.
Overall, the PHET Colorado Greenhouse Simulation is a useful and engaging tool for learning about the science behind the greenhouse effect and climate change. It allows users to explore the mechanisms behind the greenhouse effect and see the consequences of increasing greenhouse gas levels in the atmosphere. By manipulating various factors that influence the Earth's temperature, users can gain a deeper understanding of the complex factors that influence our planet's climate and the importance of taking action to mitigate climate change.

What happens to the sunlight photons as they hit the ground? Please note that this resource requires at least version 1. Are all of the sunlight photons being reflected back into space? Sunlight is the ultimate source of most of the energy we use. As a result, a material tends to cool down unless some other form of energy is converted to thermal energy in the material. Once it is properly running you will see a screen like this: Questions :. Change the greenhouse gas concentration and see how the temperature changes.

Then compare to the effect of glass panes. In this practical sense, energy gets "used up," even though it is still around somewhere. The energy in fossil fuels such as oil and coal comes from energy that plants captured from the sun long ago. The earth's climates have changed in the past, are currently changing, and are expected to change in the future, primarily due to changes in the amount of light reaching places on the earth and the composition of the atmosphere. When greenhouse gases increase, more thermal energy is trapped in the atmosphere, and the temperature of the earth increases the light energy radiated into space until it again equals the light energy absorbed from the sun. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. The next couple steps will depend on the computer you are using, but it will probably require you to download the file, save the file in your downloads folder, then going to that file in your downloads folder and using Java to open the file.
Some bounce off the clouds while some pass through. In a second simulation, the Greenhouse Effect caused by glass is illustrated. Explore the atmosphere during the ice age and today. Instead of bouncing off the ground they go through the surface land. Light and other electromagnetic waves can warm objects.
Simulations are often useful in modeling events and processes. They are also used for processes that are too vast, too complex, or too dangerous to study. By burning fuels, people are releasing large amounts of carbon dioxide into the atmosphere and transforming chemical energy into thermal energy which spreads throughout the environment. One goal in the design of such devices is to make them as efficient as possible—that is, to maximize the useful output for a given input. Zoom in and see how light interacts with molecules.
Users may opt to add cloud cover to the simulation to observe the resulting temperature changes. This simulation explores how greenhouse gases effect the climate. How much an object's temperature increases depends on how intense the light striking its surface is, how long the light shines on the object, and how much of the light is absorbed. Do all atmospheric gases contribute to the greenhouse effect? Human inventiveness has brought new risks as well as improvements to human existence. It gradually rises, but slowly decreases after time. Please refer to the style manuals in the.

PhET Simulation: The Greenhouse Effect
The useful energy output of a device—that is, what energy is available for further change—is always less than the energy input, with the difference usually appearing as thermal energy. The human species has a major impact on other species in many ways: reducing the amount of the earth's surface available to those other species, interfering with their food sources, changing the temperature and chemical composition of their habitats, introducing foreign species into their ecosystems, and altering organisms directly through selective breeding and genetic engineering. Although the earth has a great capacity to absorb and recycle materials naturally, ecosystems have only a finite capacity to withstand change without experiencing major ecological alterations that may also have adverse effects on human activities. What happens to the temperature when you add clouds? Greenhouse gases in the atmosphere, such as carbon dioxide and water vapor, are transparent to much of the incoming sunlight but not to the infrared light from the warmed surface of the earth. During any transformation of energy, there is inevitably some dissipation of energy into the environment. The Physical Setting 4B.

Over time, the thermal energy tends to spread out through a material and from one material to another if they are in contact. They hit the ground and hit back into the atmosphere. What happens to the sunlight photons as they hit the ground? The user can select the level of atmospheric greenhouse gases during an ice age, in the year 1750, today, or some time in the future and see how the Earth's temperature changes.

Thermal energy is transferred through a material by the collisions of atoms within the material. .

How are the photons affected by adding clouds? Because the transfer of energy from these resources is weak and variable, systems are needed to collect and concentrate the energy. Thermal energy can also be transferred by means of currents in air, water, or other fluids.
Record: CO2 280 ppm CH4 0. In addition, some thermal energy in all materials is transformed into light energy and radiated into the environment by electromagnetic waves; that light energy can be transformed back into thermal energy when the electromagnetic waves strike another material. The burning of fossil fuels in the last century has increased the amount of greenhouse gases in the atmosphere, which has contributed to Earth's warming. Go to: Ice Age 1. Energy from the sun and the wind and water energy derived from it is available indefinitely. Levels of four greenhouse gases are displayed:water, carbon dioxide, methane, and nitrous oxide.
