WHY IS THE SKY BLUE?
GASES IN THE AIR SCATTER SHORT WAVELENGTHS OF VISIBLE LIGHT (BLUE AND VIOLET)AND THERE ARE THAN LONG WAVELENGTHS PRESENT (RED AND ORANGE)
WHAT HAPPENS TO THE ENERGY THAT IS ABSORBED BY THE EARTHS SURFACE?
THE LAND AND WATER ARE HEATED
HOW MIGHT EARTH BE DIFFERENT WITHOUT THE GREENHOUSE EFFECT?
THE TEMPERATURE WOULD BE VERY DIFFERENT
