The three main types of mountains derive their names from how they form. Since it takes millions of years for mountains to form, there are some events that help mountains to form as they are. One is the collision of plates. The second is caused by the eruption of volcanoes. The third is the formation of mountains generated along mountain fault lines with some large blocks of rock forcing themselves upwards while others are forcing themselves down.
urban areas are mostly characterised by high population advanced technology and basic amenities. The population helps to increase productivity which leads to economic development, employment opportunities that promotes increase in standard of living which in turn helps economic development.
