Why has the greenhouse effect been much more effective in raising the surface temperature on Venus than on Earth?
A) The solar wind,the major cause of heating in the greenhouse effect,is far more intense at Venus's distance from the Sun,and Venus has no magnetic field to deflect it.
B) The oceans on Earth have acted as a thermostat in absorbing much of the heat that would otherwise have raised Earth's temperature significantly.
C) CO2,which traps heat from the planet's surface,is the major component in the very dense Venusian atmosphere but only a minor constituent of Earth's atmosphere.
D) The surface of Venus is much more effective than that of Earth in absorbing solar visible and UV radiation.
