Answer:
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.
True. At a steeper gradient the velocity of the river is greater, combined with more discharge in the river the ability of the river to transport load increases as it has more energy.
<span>B. landforms created from secondary landforms is not necessarily considered as a classification for landforms.

If air pressure rises, a high pressure cell is on the way and clear skies can be expected. If pressure falls, a low pressure cell is coming and will likely bring storm clouds. Barometric pressure data over a larger area can be used to identify pressure systems, fronts, and other weather systems.
Hope this helps.
