What were the carbon dioxide levels during the ice age?
During the last ice age, carbon dioxide levels were around 180-200 parts per million (ppm) compared to pre-industrial levels of approximately 280 ppm. This reduction in CO2 levels contributed to the lower temperatures and the expansion of ice sheets during the ice age.
Why was the British isles joined together with the rest of Europe during the ice age?
low sea levels
When the glaciers that covered large parts of Earth melted after the last ice age did the the sea levels become higher?
Yes, as the glaciers melted after the last ice age, the water flowed into the oceans, causing sea levels to rise. This phenomenon is known as post-glacial sea level rise and it has led to changes in coastlines and the flooding of low-lying areas.
What was the impact of the ice age on sea levels?
During the ice age, large amounts of water were trapped in glaciers and ice sheets, causing sea levels to drop significantly. As a result, coastlines receded and land bridges emerged between continents, allowing the migration of animals and humans. When the ice age ended and the glaciers melted, sea levels rose, flooding low-lying areas and reshaping coastlines.
Why was the maunder minimum little ice age so cold?
The Maunder Minimum, a period of low sunspot activity from 1645 to 1715, is associated with the Little Ice Age due to reduced solar energy reaching Earth's surface. This resulted in colder temperatures globally. Additionally, volcanic eruptions during that time could have contributed to the cooling by releasing ash and aerosols into the atmosphere, which reflected sunlight and further cooled the climate.

What was the theory of how people came to the Americas?
The clasic theory is that people from northern Asia crosses the Bering Straights - possibly during an ice age (with low sea levels).
What was not a thick snow or ice center in North America during the Ice Age?
The North American ice sheet during the Ice Age did not cover the central Great Plains region, which remained largely ice-free due to its relatively low precipitation levels. This area is known as the "ice-free corridor" and served as a passageway for plants, animals, and potentially human migration.
Why was the British isles joined together with the rest of Europe during the ice age?
low sea levels
What happens to oceans levels during an ice age?
During an ice age, the sea level generally drops because water is stored in ice sheets on land. When the ice sheets melt during interglacial periods, sea levels rise again. This cycle of rising and falling sea levels is a natural phenomenon in Earth's climate history.
What does period during which low temperatures caused large areas of earths warter to freeze mean?
That would be an ice age.
Does Lithuania have any mountains?
No. It doesn't have any mountains higher than 300m (the same as a large hill). The reason for this is that during the ice age all the hills and mountains were wiped out during the last ice age and replaced by low lying swamps and drumlins.
What does it mean when you eat crushed ice?
it could mean you have low iron levels
How was Europe separated?
All landmasses on Earth are constantly shifting and rearranging. The British Isles most likely just broke off as all landmasses do at one point or another. However, during the Ice Age (for example), the British Isles and Europe were connected due to the low sea levels. But once the ice melted, sea levels rose and the land bridge disappeared.

What are some atmospheric conditions during the mesozoic era?
low oxygen levels
