"It was the Cretaceous-Tertiary or the K-T Extinction." - Wrong
The K-T Extinction was the mass extinction that wiped out the dinosaurs, which was more widely believed to be caused by a heavenly body colliding with the Earth.
The mass extinction that involved a large period of glaciation was in truth the Ordovician-Silurian Extinction, which was the earliest mass extinction.
The extinction is associated with a period of glaciation. First, sea levels dropped as glaciers formed. Later, as the glaciers melted, the sea level rose. The cause of this glaciation remains a mystery. One suggestion is land plants caused it by absorbing large amounts of carbon dioxide from the atmosphere. The drop in carbon dioxide could then have caused global cooling.
The Permian-Triassic Extinction
No. It was all ready there.
No the formation of the moon could not have caused the Paleozoic Era to go extinct.
Caused the formation of fjords, Created thousands of lakes, Left the soil rocky.

Yosemite Valley was formed by glaciers carving their way through the valley as they retreated. The glaciers are credited with forming the sheer cliff sides of the valley.
Glacers over the land near Michigan and Ontario that Melted over time creating these massive lakes.
Glaciers are not as prevalent in southern continents like South America, Africa, Australia, and Antarctica today because of the warmer temperatures. Climate change has caused glaciers to melt and retreat in these regions, making them less common compared to the northern continents where they still exist.
Canadian Shield is the flat rock formation that covers northern ontario. It was caused my glaciers scraping the soil away.

A meteor impact caused the extinction of the dinosaurs.

The fennec is in no danger of extinction. It is classified as a species "of least concern."
