Where do new sections of crust come from during seafloor spreading?

1 answer:

5 0

Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.

Answer:

Pacific Ocean formed by the same processes that cause the current geologic activity and Beautiful mountains are the reasons why many people live on the Ring of Fire.

Explanation:

The volcanic islands around the Pacific ocean have formed on the tectonic plates due to various geologic processes. These islands have highly fertile soil and geothermic energy from the underground steam caused due to the volcanic magma can also be harnessed to obtain an economic advantage. There's also an incredible scenery with various volcanic mountains and hot geysers that attract hundreds of tourists from all over the world. This provides various job opportunities in the field of tourism.
