periodic glaciation at a global scale is a feature of which geological age
Answers
Answer:
Similarly, an interglacial or interglacial period is the warmer period of time between ice ages where glaciers retreat and sea levels rise. Over the last 450,000 years, glacials have lasted anywhere from 70,000 to 90,000 years whereas interglacials last approximately 10,000 years
Answer:
By 1985 a number geological societies agreed to set the beginning of the Pleistocene Epoch about 1,800,000 years ago, a figure coincident with the onset of glaciation in Europe and North America.
Explanation:
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances.
Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago.[1] The Holocene is the current interglacial. A time with no glaciers on Earth is considered a greenhouse climate state.
