Answer:
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.

Answer:
mechanical weathering
Explanation:
As a definition, mechanical weathering is the disintegration and decomposition of rocks on or on the earth's surface produced by different atmospheric, climatic and biological agents.
Weathering is a permanent process in nature.
It is also defined as a static process by which the rock breaks into small fragments, dissolving and decomposing to form new minerals. This is the way in which the removal and transport of detritus then results in erosion. It follows that weathering, by reducing the consistency of the stone masses leads to the erosion process.
The causative agents of the weathering of the stones, (external geological agents) can be physical (mechanical), chemical and biological.
