What are two ways in which comets are different from other celestial bodies?

a. nucleus is rocky, with dust and ice; often found between mars and jupiter
b. nucleus is a gas ball; usually come from far away from the sun
c. nucleus of dust, rocks, and ice; may have a long, gaseous trail
d. called a meteor as soon as it develops the long gaseous tale; may have an orbit that takes more than 100 years to complete

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

what is the question because that is not a question.

the inner core.

good luck: )
