What Is the MAIN Reason That the Greenhouse Effect Has

question 102

Multiple Choice

What is the MAIN reason that the greenhouse effect has been much more effective in raising the surface temperature on Venus than in raising the surface temperature on Earth?

• A) The solar wind, the major cause of heating in the greenhouse effect, is far more intense at Venus' distance from the Sun, and Venus has no magnetic field to deflect this solar wind.
• B) Carbon dioxide, which traps heat from the planet's surface, is the major component in the very dense Venusian atmosphere, while it is a only a minor constituent of Earth's.
• C) The oceans on Earth have acted as a thermostat in absorbing much of the heat that would otherwise have raised Earth's temperature significantly.
• D) The surface of Venus is much more effective than the surface of Earth in absorbing solar visible and UV radiation.
