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.

Is it true that Ocean levels rise during an ice age due to an increase in moisture retention in Earth's global biosphere?

No, ocean levels do not rise during an ice age due to an increase in moisture retention in Earth's global biosphere. During an ice age, water is locked up in ice sheets and glaciers, causing sea levels to drop. The lowered sea levels expose more land, which can lead to an expansion of ice sheets and further cooling.


Why did the oceans become shallower during the last ice age?

Much of North America, and other parts of the globe were covered in ice that was as much as two or three kilometers thick. Remnants of those glaciers are still with us. And also to a lesser extent in some of the Earth's mountain ranges such as the Rocky Mountains.Much of the precipitation that originated as evaporation from the surface of the oceans fell as snow over the land and formed into glaciers. That was the reason the ocean levels were lower than they are today.


How did the climate change during the stone age?

During the Stone Age, the climate experienced natural fluctuations, including glacial and interglacial periods. These shifts impacted temperatures, ice cover, and sea levels, affecting vegetation and shaping human behaviors and migrations. The climate during this time was characterized by a generally cooler global temperature compared to present day.


How will Hawaii be affected by an ice age?

During an ice age, Hawaii may experience cooler temperatures and potentially increased precipitation due to changes in global climate patterns. Sea levels may also drop, impacting coastal areas of the islands. However, Hawaii's isolation and unique geography may offer some protection from the more extreme effects seen in continental regions during an ice age.


Occur when the Earth comes out of an ice age?

Inter-glacial periods occur when the Earth transitions from a glacial period (ice age) to a warmer period. During these periods, temperatures increase, ice sheets retreat, and sea levels rise. Inter-glacials are characterized by a warmer climate, with higher levels of carbon dioxide in the atmosphere.

What do sea levels do during an ice age?

During an ice age, sea levels typically drop because a significant amount of water becomes locked up in glaciers and ice sheets on land. As the ice sheets expand, they draw water from the oceans, causing sea levels to decrease.


During the Ice Age the ocean levels were than now.?

Lower


Ocean levels were much lower during the Ice Age than they are now because .?

More of the earths water was frozen


Why are ocean levels lower in the ice age then now?

During the ice age, much of the Earth's water was locked up in large ice sheets, causing sea levels to be lower than they are today. As the ice sheets melted and retracted over time, the water they released flowed into the oceans, gradually raising sea levels to their current levels.


What happend to the oceans during the ice Age?

they formed new ones


During an ice age what is likely to happen to the levels of oceans around the world?

they would rise because the ice being created will have more mass... so if global warming happens the sea level will stay approximately the same because although the north/south poles will lose mass places like greenland etc will melt their ice and the ice caps melting will be cancelled out.


Ask us anythingDuring the Ice Age the ocean levels were than now.?

During the Ice Age, ocean levels were lower than they are now due to the amount of water being locked up in glaciers and ice sheets on land. As these ice sheets melted, they released water back into the oceans, causing sea levels to rise.


What would happen to the oceans if surface runoff and groundwater flow were reduced for example by the growth of ice sheets during an ice age?

If surface runoff and groundwater flow were reduced due to the growth of ice sheets during an ice age, the input of freshwater into the oceans would decrease. This could potentially lead to a rise in salinity levels in the oceans, affecting marine life adapted to specific salinity levels. It may also impact ocean circulation patterns and potentially disrupt the global climate system.


During an ice age earths sea level?

During an ice age, Earth's sea level generally drops because water is locked up in the polar ice caps and glaciers. This causes less water to be in the oceans, leading to lower sea levels compared to during interglacial periods.


How are the area and the oceans affected during ice age?

During an ice age, large parts of Earth's land area can be covered by ice sheets and glaciers, leading to lower global sea levels as water is locked up in ice. The oceans can be affected by changes in circulation patterns due to the redistribution of ice and changes in temperature and salinity, which can impact marine ecosystems and weather patterns.

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.
