Which of these statements is true about heating up air in the lower atmosphere? It occurs mainly through radiant energy.
It occurs through convection from Earth.
It happens to a different extent over land and water.
It takes place through conduction between the sun and air.

i think its 100

i hope this !

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.

i think tornado but not 100%
