Earth's Precession
Earth's precession
Earth's ice ages are primarily thought to be caused by variations in the Earth's orbit and tilt, known as Milankovitch cycles. These cycles affect the amount and distribution of sunlight reaching the Earth, leading to fluctuations in global temperatures and the growth or retreat of ice sheets. Additional factors such as changes in greenhouse gas concentrations and volcanic activity can also influence the onset and duration of ice ages.
The currently accepted theory is that ice ages are caused by changes in Earth's orbit and tilt, known as Milankovitch cycles. These cycles affect the amount of sunlight reaching different parts of the Earth, leading to fluctuations in temperature and the growth and retreat of ice sheets. Other factors, such as volcanic activity and variations in greenhouse gas concentrations, can also influence the climate and contribute to the onset of ice ages.
The two main causes of ice ages are:reduction in greenhouse gasses in atmospheredimming of the sunThere has been much debate among scientists which of these was the primary cause of different ice ages and which other secondary causes lengthened or shortened them.
Ice ages are long periods of global cooling, characterized by the expansion of ice sheets and glaciers. Within ice ages, there are shorter periods called interglacial periods, which are characterized by warmer temperatures and the retreat of ice sheets. Interglacial periods occur between ice ages and are marked by relatively milder climates.

Sometimes continental drifts cause ice ages. Most of the time they are caused when ice glaciers cover parts of the Earth.

It is thought that there were 5 major ice ages in Earthâ??s history. The most recent event was over 2 million years ago, and was in the Quaternary period.
true
the romans all thought that it was bad swamp air that caused disease, they thought it was natural causes that caused disease whereas, the people in the middle ages thought that it was spirits that caused disease.
Ice Ages - band - was created in 1994.
The ice age caused the area between Russia and Alaska to freeze into ice that people could walk on but the Asian hunters also followed the bison to the Americas for food

by ice melting
Over time, their have been many ice ages
