Greenhouse Effect PhET

In the simulation, adjust the level of greenhouse gases and observe the effect on Earth's temperature. What happens when the concentration of greenhouse gases increases?

• A) The Earth's temperature decreases.

• B) The Earth's temperature increases.

• C) The Earth's temperature stays the same.

• D) The Earth's temperature fluctuates unpredictably.

In the simulation, reduce the level of greenhouse gases and observe the temperature changes. What happens to the Earth's temperature when the level of greenhouse gases is reduced?

• A) The temperature decreases.

• B) The temperature increases.

• C) The temperature stays the same.

• D) The temperature fluctuates unpredictably.

In the simulation, observe how heat is trapped in the atmosphere. How do greenhouse gases affect the heat trapped in Earth's atmosphere?

• A) They allow heat to escape freely.

• B) They reflect heat back toward the Earth's surface.

• C) They absorb all the heat and stop it from leaving the atmosphere.

• D) They trap heat at high altitudes only.

In the simulation, observe the effect of clouds on the Earth's temperature. What happens when clouds are added to the atmosphere in the simulation?

• A) The temperature increases significantly.

• B) The temperature decreases slightly.

• C) The temperature stays the same.

• D) The temperature fluctuates unpredictably.

Observe the effect of removing the greenhouse gases from the atmosphere. What happens to the Earth's temperature when all greenhouse gases are removed?

• A) The temperature increases rapidly.

• B) The temperature decreases significantly.

• C) The temperature stays the same.

• D) The temperature fluctuates randomly.

In the simulation (layer model), experiment with different levels of sunlight and observe the impact on the Earth's temperature. What happens when the amount of sunlight is reduced while keeping the greenhouse gas levels constant?

• A) The Earth's temperature increases.

• B) The Earth's temperature decreases.

• C) The temperature stays the same.

• D) The temperature fluctuates randomly.

In the simulation, observe the interaction between the Earth’s surface and the atmosphere. What happens when the Earth’s surface absorbs more heat than it can radiate back?

• A) The Earth cools down.

• B) The Earth’s temperature stabilizes.

• C) The Earth’s temperature increases.

• D) The heat is reflected back into space.

After going through the simulation, how would you sum up the impact of greenhouse gases on the earth's temperature and how it happens?
