- WHAT ARE ELECTROMAGNETIC WAVES?
- A FORM OF ENERGY THAT CAN MOVE THROUGH THE VACUUM OF SPACE
- MOST OF THE ENERGY FROM THE SUN TRAVELS TO THE EARTH HOW?
- IN THE FORM OF VISIBLE LIGHT AND INFRARED RADIATION- A SMALL AMOUNT AS ULTRAVIOLET RADIATION
- WHAT IS INFRARED RADIATION?
- INVISIBLE FORM OF ENERGY WITH WAVELENGTHS THAT ARE SHORTER THAN VIOLET LIGHT
- WHAT IS RADIATION?
- THE DIRECT TRANSFER OF ENERGY BY ELECTROMAGNETIC WAVES
- WHAT IS VISIBLE LIGHT?
- INCLUDES ALL THE COLORS YOU SEE IN A RAINBOW
- WHAT COLORS HAVE THE LONGEST WAVELENGTHS?
- RED AND ORANGE
- WHAT COLORS HAVE THE SHORTEST WAVELENGTHS?
- BLUE AND VIOLET
- WHAT IS ULTRAVIOLET RADIATION?
-
INVISIBLE FORM OF ENERGY WITH WAVELENGTHS THAT ARE SHORTER THAN VIOLET LIGHT
- CAN CAUSE SUNBURNS - DESCRIBE THE PATH OF THE SUN'S RAYS
- ABOUT HALF OF THE SUNS ENERGY IS EITHER REFLECTED BACK INTO SPACE OR ABSORBED INTO THE ATMOSPHERE. THE REST REACH THE EARTH'S SURFACE
- THE OZONE LAYER ABSORBS MOST OF WHAT?
- ULTRAVIOLET RADIATION
- WATER VAPOR AND CARBON DIOXIDE ABSORB WHAT?
- INFRARED RADIATION
- WHAT IS SCATTERING?
- DUST PARTICLES AND GASES IN THE ATMOSPHERE REFLECTING LIGHT IN ALL DIRECTIONS
- WHEN THE EARTH'S SURFACE IS HEATED, IT RADIATES MOST OF THE ENERGY BACK AS WHAT?
- INFRARED RADIATION
- WHAT IS THE GREENHOUSE EFFECT?
- THE PROCESS BY WHICH GASES HOLD HEAT IN THE AIR
- WHAT ARE 3 FORMS OF RADIATION FROM THE SUN?
- VISIBLE LIGHT, INFRARED RADIATION AND ULTRAVIOLET RADIATION
- WHICH FORM OF RADIATION FROM THE SUN HAS THE LONGEST WAVELENGTHS?
- INFRARED RADIATION
- WHICH FORM OF RADIATION FROM THE SUN HAS THE SHORTEST WAVELENGTHS?
- ULTRAVIOLET RADIATION
- WHAT HAPPENS TO MOST OF THE SUNLIGHT THAT REACHES THE EARTH?
- 50% IS ABSORBED BYTHE EARTHS SURFACE AND IS USED TO HEAT THE LAND AND WATER
- WHAT PERCENTAGE OF SUNLIGHT IS REFLECTED BY CLOUDS, DUST AND GASES IN THE ATMOSPHERE?
- 25%
- WHAT PERCENTAGE OF SUNLIGHT IS ABSORBED BY PARTICLES AND GASES IN THE ATMOSPHERE?
- 20%
- WHY ARE SUNSETS RED?
- WHEN THE SUN IS SETTING THE LIGHT IS PASSING THRU A THICKER AREA OF THE ATMOSPHERE -LIGHT FROM THE BLUE END OF THE SPECTRUM IS SCATTERED AND THE REMAINING LIGHT IS RED AND ORANGE
- 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
