During a solar eclipse, when the Moon's shadow falls on the Earth, we stand in the shadow rather than looking at it. Observers standing in the umbra see a total eclipse of the Sun, while observers under the penumbra see a partial eclipse.
Answer:
The ‘greenhouse effect’ is how carbon dioxide, methane, water vapour and other molecules absorb the energy of specific wavelengths of electromagnetic radiation (i.e. light), and transfer parts of that energy to the atmosphere as heat. The effect stabilizes the earth’s temperature at levels that permit liquid water to exist. In other words, permit life forms as we know them.
The ‘enhanced greenhouse effect’ is the additions to the above effects caused by human activities that increase the concentrations of greenhouse gases in the atmosphere.
