Why does sea level rise and fall during inter glacial and glacial periods?
Sea level rises and falls during glacial and interglacial periods due to changes in the volume of ice stored on land. During glacial periods, glaciers and ice sheets expand, drawing water from the oceans and lowering sea level. In contrast, during interglacial periods, these ice masses melt and contribute water to the oceans, causing sea levels to rise.
How could the glacial period and the interglacial period effect the early humans?
Yes. Notably as the ice melted, the sea level rose, and habitation had to move further inland. Other effects such as grazing range of animals, and the climate change itself, changing the vegetation.
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.
Does glacial advance decreases or increases sea level?
Glacial advance can decrease sea level because it locks up water in the form of ice on land, reducing the amount of liquid water in the oceans.
Why does the sea level fall during glacial periods?
The only way for sea levels to fall is if the water goes somewhere else. Where else could it go? It could remain on land, but only if it was frozen. That is the answer. If precipitation always falls as snow and hail and the climate is cold enough, like Antarctica, then the frozen water builds steadily up on land. More and more water comes out of the oceans and then falls frozen onto land, where it stays there.

Why does sea level rise and fall during interglial and glacial periods?
The reason why sea levels drop during the glacial era is because that ocean water gets locked up in the ice caps. Sea levels drop due to the removal of large volumes of water above sea level in the icecaps
What happens to global sea level during a glacial period?
Sea levels drop globally during a glacial period as seawater is taken up in the ice sheets.
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.
Are glaciers dissapearing?
No, there are still glaciers in California, Washington, Montana, Colorado...pretty much everywhere they have been, just a bit smaller. A disproportionate amount of sea level rise in recent decades has been due to the melt of such glaciers (i.e. midlatitude alpine glaciers) rather than the more media-friendly polar ice sheets.
Does glacial advance decreases or increases sea level?
Glacial advance can decrease sea level because it locks up water in the form of ice on land, reducing the amount of liquid water in the oceans.
How were the land masses organized?
During interglacial periods the land bridges would disappear and the sea level would rise rapidly. When the ice retreats newly shaped mountains appear and water drains into large basins like the Great Lakes. Also the wind and ocean currents change. This continual pattern of rise and fall in sea level is what caused erosion of the major land masses and how they developed their present day shape.

Why did the sea level drop around 60000 bc?
Around 60,000 BC, the sea level dropped due to the expansion of ice sheets and glaciers during the last glacial period. This period, known as the Last Glacial Maximum, resulted in more water being locked up in ice, leading to lower sea levels globally.
What was the earth's sea level during the ice age?
During the last ice age, approximately 20,000 years ago, global sea levels were around 130 meters (426 feet) lower than they are today. This drop in sea level was due to a large amount of water being locked up in ice sheets covering much of North America and Eurasia.
Why is earth's sea level lower during an ice age?
Ice ages have thick glaciers and ice caps over many lands that today are ice-free. The amount of water on earth doesn't change, so vast amounts of land ice means there is less water in the oceans and the sea-level is lower.When snow doesn't melt during the summer, it builds up on the land, compressing the lower layers to turn it into ice. That snow has to come from somewhere. Water evaporates from the oceans, the wind blows it over the cold land turning it into snow. Eventually, so much water is evaporated from the oceans it causes their levels to fall.A:Basically because that ocean water gets locked up in the ice caps. Within the ice ages (or at least within the last one), more temperate and more severe periods occur. The colder periods are called glacial periods, the warmer periods interglacials, such as the Eemian Stage.Glacials are characterized by cooler and drier climates over most of the Earth and large land and sea ice masses extending outward from the poles. Mountain glaciers in otherwise unglaciated areas extend to lower elevations due to a lower snow line. Sea levels drop due to the removal of large volumes of water above sea level in the icecaps. There is evidence that ocean circulation patterns are disrupted by glaciations. Since the Earth has significant continental glaciation in the Arctic and Antarctic, we are currently in a glacial minimum of a glaciation. Such a period between glacial maxima is known as an interglacial.The Earth has been in an interglacial period known as the Holocene for more than 11,000 years. It was conventional wisdom that "the typical interglacial period lasts about 12,000 years," but this has been called into question recently. For example, an article in Nature argues that the current interglacial might be most analogous to a previous interglacial that lasted 28,000 years. Predicted changes in orbital forcing suggest that the next glacial period would begin at least 50,000 years from now, even in absence of human-madeglobal warming (see Milankovitch cycles). Moreover, anthropogenic forcing from increasedgreenhouse gases might outweigh orbital forcing for as long as intensive use of fossil fuels continues. At a meeting of the American Geophysical Union (December 17, 2008), scientists detailed evidence in support of the controversial idea that the introduction of large-scale rice agriculture in Asia, coupled with extensive deforestation in Europe began to alter world climate by pumping significant amounts of greenhouse gases into the atmosphere over the last 1,000 years. In turn, a warmer atmosphere heated the oceans making them much less efficient storehouses of carbon dioxide and reinforcing global warming, possibly forestalling the onset of a new glacial age.
