The number of microcontinents decreased and the size increased
Explanation:
The Proterozoic Era was between 570 million years and 2500 million years ago. It comprises of the Late, Middle and Early Era.
Small Proterozoic continents are called microcontinents. These microcontinents collided and thus their numbers decreased but their resultant collision produced high altitude massive mountain ranges of increased size. This convergence to form a continent of increase size was active between 1.5 and 10 billion years ago. What was formed by this collision was called the continent of Laurentia, which covered about 70% of the earth at that time.
