A glacial period is like the time of ice ages, when the most of the earth is covered in ice and snow.
The ages of the rocks become older the farther the way they are from the ridges. The closer they are the younger it is. This leaves evidence to the seafloor spreading theory.
Some also say: ice age = all of the ice ages (a general name). Ice Age = Pleistocene Glacial Epoch.
Technically, yes. Ice ages are not continuous periods of cold, but rather have cycles of colder glacial periods and warmer interglacial periods. We are currently in an interglacial period.
Geologists have learned to use growth rings in shells, as well as rhythmic layering in sediments and in glacial ice, to date events numerically back through recent Earth history.
(Glacial can refer to actual glaciers, or metaphorically to things that are either cold or slow-moving.)During the ice ages, glacial expansion covered much of the land closest to the poles.He tried a cheery greeting to the receptionist, but was met by a glacial stare.The controversial bill moved at a glacial pace through a myriad of subcommittees.

No: glacial activity occurs in all glacial phases of all Ice Ages, and we now see the results of the latest within the present Ice Age.

There have been multiple glacial periods, known as ice ages, during the last two million years. These ice ages are characterized by intervals of cold climate when ice sheets covered much of the Earth's surface. The exact number of glacial periods can vary depending on the scientific definition used.
