Answer to Question 1

B

Answer to Question 2

The white zones of Jupiter's atmosphere are white because of ammonia clouds. The red and brown colors of the belts are produced by light reflected from deeper ammonium-hydrosulfide clouds. Saturn's reds and tans probably come from the same compounds that produce these colors on Jupiter. However, they are more muted because these cloud layers lie deeper within Saturn's atmosphere, under a thicker layer of tan smog. The blue colors of Uranus and Neptune are produced by methane gas, which absorbs red light and transmits blue.
