Gas planets and terrestrial planets have lots of differences. Gas planets are huge in size, while the terrestrial planets are small. Gas planets have very strong gravitational pull, while the terrestrial planets have more moderate gravitational pull. Gas planets consist mainly (not totally) of gas (hydrogen, helium, ammonia, water, methane), while terrestrial planets are mostly made out of rock, with iron core. Gas planets have atmospheres that are very dense and multilayered that consist of the aforementioned gasses, while terrestrial planets have atmospheres that they have manufactured geologically. <span />

Oceania has about 30 million inhabitants that cover land of about 9 million km2. Australia alone accounts for 85% of this area and concentrates 60% of the population. The other islands, which number close to 10 thousand, are divided into three large groups:
Melanesia: covers the islands located in the Northeast of Australia, from New Guinea to the Fiji Islands.
Polynesia: extends from New Zealand to Hawaii.
Micronesia: comprises the islands located in the north of Melanesia.
-Fertility rate: The factor which affects the growth of the population in the biggest way is the fertility rate.
-Mortality rate: A key factor affecting the growth of the population is the death, or mortality, rate. Just as the birth of new people increases the population size, deaths decrease it.
-Immigration and Emigration: Cross-border migration is the act of people moving from one country to another. It affects the population size of both the host and destination countries. Emigration is caused by a number of factors, such as fleeing war, finding education, seeking new jobs or joining family members. When a person emigrates from a country, its population shrinks.
