During that time there was widespread volcanic activinty and trees and flowering plants started appearing

During the devonian time period most of land was under water.
Precambrian is BEFORE the Cambrian period!

No. Precambrian rocks are exceptionally rare. That period ended 570 million years ago, and the oldest rocks on the surface of the Earth are in the Laurentian Range, which runs from Southern Quebec down into Texas and Mexico.
The Precambrian time period is segmented into very few parts because:

Type your answer here... it was wet and the surface was covered with a thin layer of warm water.

Over most of Precambrian time 80 percent of earths history-the only life forms are bacteria ,which appear about 3,500 million years ago. multiple-cells marine animals like spriggina appear at the end of the era

Most likely during the Precambrian, Cretaceous PERIOD
It looked like a sphere
In Precambrian times, a relative shortage of volcanoes resulted in low emissions of carbon dioxide. This contributed to low surface temperature, and a lot of glaciers towards the end of the period.
