greenhouse effect?

Question

can someone please explain the greenhouse effect to me

thanks

Answer 1

The Greenhouse Effect is indeed a catchy term, but it serves a purpose. Without the Greenhouse Effect, earth would be cold and desolate. Our ozone layer blocks most of the harmful radiation from the sun and allows heat, visible light and UV light in our atmosphere. Some of that energy is absorbed and the rest is reflected. The ozone layer acts as a barrier and again reflects that energy back down towards the earth thereby heating the air and the ground.

Help at all?

Answer 2

You know how those greenhouses have glass walls, well the atmosphere is like a glass wall to the earth and serves the same purpose. To trap some of the heat from the sun for warmth which is needed for growth.

Answer 3

"greenhouse effect" is a catchy term coined by environmentalists to attempt to relate global warming to human activity. In other words it's more of an emotional stimulant than a geological or scientific theory.

Here's a quote from a recent issue of one of the publications of the American Association of Petroleum Geologists. I believe this is the largest society of geoscientists on Earth:

its basically when the sun heats up the earth during the day heat is absorbed by the ground and such and at night it is released thats why on a cloudy night is hotter, anyways with CO2 emissions and such the heat at night is trapped in and can't escape the atmosphere so over time the planet heats up
