<span>An ice age is the amount of the Earth's water that is locked up on land in the form of glaciers.
</span>According to the scientists, an ice age occurs every 100,000 years. There are five major ice ages in the Earth's history. That are the Andean-Saharan, Huronian, Karoo Ice Age, Cryogenian, and the current Quaternary glaciation.
But, If we entered another ice age currently, it would increase the amount of locked water in the form of glaciers and hence it would have huge consequences for human civilization and the ecosystem.
Part 1: Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continuous circulation pattern.
Part 2: The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates.
