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?
Today, ice covers Earth's North and South poles. These ice caps are called polar glaciers. During an ice age, the polar glaciers grow larger. At the height of an ice age, glaciers may cover as much as a third of the Earth. Canada, the northern United States, northern Europe, and northern Russia all get covered by ice. This ice can be more than a mile (1.6 kilometers) thick. Much of the world's water gets frozen to make these glaciers. This water comes from the oceans, and sea level drops as a result. Places that had been under water become dry land. Many plants and animals adapt to these changes. Those that do not adapt die out. During the last ice age, animals with warm shaggy coats flourished. For example, the woolly mammoth, a large elephant-like animal, roamed icy areas of Earth. The mammoths probably used their huge tusks to scrape away the snow in search of plants to eat. Their thick woolly coats protected them from the cold.
Can a river freeze during the winter months?
Yes, a river can freeze during the winter months when the temperature drops low enough for the water to solidify into ice.

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 does period during which low temperatures caused large areas of earths warter to freeze mean?
That would be an ice age.
What happens to oceans levels during an ice age?
Sea level can drop on the order of 100 meters. During the last glacial maximum, when the last ice age was in full swing and continental ice masses variously reached their greatest extents, considered to be the millennia centered about 21,000 calendar years ago, sea level reached 120 meters (~400 feet) lower than recent eustatic mean sea level, opening up nearly the same amount of formerly submerged land in habitable areas as was lost to ice cover and permafrost during the last 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.
