Answer:
According to the nebular hypothesis, our solar system is formed from a huge rotating cloud made mostly of helium and hydrogen.
Explanation:
The nebular hypothesis was proposed by I. Kant. It explains the formation and evolution of the Solar System. It is considered and accepted widely. The theory states that the Solar System was formed from a nebulous material. And as per nebular hypothesis, stars create the huge, dense clouds of molecular hydrogen. This hypothesis tries its best to describe the formation of the solar system from a nebula cloud that was made of a collection of dust and gas. It is also believed that the sun, planets, moons and asteroids were also born around the same time that is, around 4.5 billion years ago from a nebula.

global distribution of megacities refers to the dispersion of a population of 10 million people or more in all parts of the world.
Explanation:
Global distribution of megacities is usually determined by the number of people within a population which should not go below 10 million. these people making up the populations can be located in different locations, either in the cities or in the countryside. In January 2015, for example, China’s Pearl River Delta conurbation overtook Tokyo as the world’s largest city (Van Mead, 2016). However, this depends on how the ‘city’ is measured – the Pearl River Delta includes the cities of Shenzhen, Guangzhou, Foshan and Dongguan (but not Hong Kong, which is considered a separate territory under its ‘Special Administrative Zone’ status within China). If these cities were measured separately, Tokyo would likely remain the world’s largest city.
