During a glacial period (ice-age), a lot of water is held as ice, so lowering the sea level. When the ice melts during an interglacial period, the released water raises the sea level.
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.
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, 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.
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.
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.

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
Sea levels drop globally during a glacial period as seawater is taken up in the ice sheets.

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.

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.

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.
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.
You can get the answers here and you can go and ask to your gynecologist also. Mood swings are common during periods. This happens due to hormonal changes. Both the estrogen and progesterone level drops down before periods.
