How does a period of glacial activity (Ice Age) begin?

Answer 1

It begins when the volume of precipitation of snow is greater than what melts. The snow and ice build up year after year. It can be caused by greater precipitation generally accompanied by cooler temperatures. Once the ice advances, it tends to reflect sunlight and heat and may result in further cooling.

Answer 2

Glacial Activity

Answer 3

very properly, i'm going to be short and candy right here. A glacial era starts with the onset of the reducing of world typical temperatures. in view that a a million degree celsius temperature drop on the equator equals extra or less a 5-7 levels celsius drop on the poles, water on the poles will start to freeze and precipitation from condensation will start to solidify into snow. and of direction, while snow piles on good of one yet another, they compress the decrease layers and given adequate time, the stack will develop right into a glacier.

Answer 4

Geoscientists do not have an answer as to what caused Pleistocene glaciation. I have heard some speculation (or theories) about altered wind patterns due to the uplift of the Himalaya Mountains, or decreased temperatures due to an increased production of calcium carbonate (in limestone), thus decreasing the total carbon dioxide in the atmosphere, but there is no definitive answer, only speculation.
