How many plates does the earth's crust have?

The relatively solid earth's crust-and  a part of the layer that lies below it divided into seven large and more than ten smaller plates float over the hot 🔥, viscous layer, which is continuously in motion-like boiling soup 🍲These flushes of heat in the earth's interior are known as 'convection cells '.At places where the convection currants push the rocks upward, the crust often breaks and gives rise 😳to a new crust. For example, the  mid ocean ridges in the Atlantic and facific oceans.
