The following steps lead to convection in the atmospheres of giant planets. Place in order. a. Gravity pulls particles toward the center. b. Warm material rises and expands. c. Particles fall toward the center, converting gravitational energy to kinetic energy. d. Expanding materials cools. e. Thermal energy heats the material. f. Friction converts kinetic energy to thermal energy

Neptune's existence was predicted because a. Uranus did not seem to obey Newton's law of motions b. Uranus wobbled on its axis c. Uranus became brighter and fainter in an unusual way d. some of the solar nebula's mass was unaccounted for

a. Uranus did not seem to obey Newton's law of motions

An occultation occurs when a. a star passes between Earth and a planet b. a planet passes between Earth and a star c. a planet passes between Earth and the Sun d. Earth passes between the Sun and a planet

b. a planet passes between Earth and a star

The Great Red spot on Jupiter is a. A surface feature b. a storm that has been raging for more than 300 years c. caused by the interaction between the magnetosphere and Io d. about the size of North America

b. a storm that has been raging for more than 300 years

The magnetic fields of the giant planets a. align closely with the rotation axis b. extend far into space c. are thousands of times stronger at the cloud tops that at Earth's surface field d. have an axis that passes through the planet's center

b. extend far into space

Zonal winds on the giant planets are stronger than those on the terrestrial planets because a. they have more thermal energy b. the giant planets rotate faster. c. the moons of giant planets provide additional pull d. the moons feed energy to the planet through the magnetosphere

b. the giant planets rotate faster.

Deep in the interiors of the giant planets, water is still a liquid even though the temperatures are tens of thousands of degrees above the boiling point of water. This can happen because a. the density inside the giant planets is so high b. the pressure inside the giant planets is so higher c. the outer solar system is so cold d. space has very low pressure

b. the pressure inside the giant planets is so higher

Which of the giant planets has the most extreme seasons? a. Jupiter b. Saturn c. Uranus d. Neptune

c. Uranus

The chemical compositions of Jupiter and Saturn are most similar to those of a. Uranus and Neptune b. the terrestrial planets c. their moons d. the sun

d. the sun

Occultation directly determine a planet's .a. diameter b. mass c. density d. orbital speed

the measured values of the changes in the brightness of the star and their duration give the information regarding the diameter and properties of the occulating belt. a. diameter
