During interglacial periods, CO2 levels are higher due to natural factors such as increased volcanic activity, changes in ocean circulation, and the release of carbon stored in soils and vegetation. These factors contribute to the higher levels of CO2 in the atmosphere during interglacial periods.

Why does sea level rise and fall during interglacial and glacial periods?
During glacial periods, sea levels drop because water is stored in continental ice sheets. During interglacial periods, ice melts and sea levels rise as water is released back into the oceans. These fluctuations in sea level are part of the Earth's natural climate cycles.
What is difference between glacial and interglacial time periods?
Glacial time periods are characterized by extensive ice sheets covering large portions of the Earth, leading to lower global temperatures and sea levels. Interglacial time periods are warmer intervals between glacial periods when the ice sheets retreat, resulting in higher global temperatures and sea levels. These cycles are driven by changes in Earth's orbit and axial tilt.
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.
What is the difference about glaciation and an interglacial period?
Glaciation refers to a period when ice sheets advance over continents, leading to colder global temperatures and lower sea levels. On the other hand, an interglacial period is a warmer interval between glaciations, characterized by the retreat of ice sheets and generally higher global temperatures.
What caused disappearance of the land bridges?
The disappearance of land bridges was primarily caused by rising sea levels during interglacial periods, such as the end of the last ice age. As temperatures increased, glaciers melted, causing the sea levels to rise and submerge the land bridges that once connected continents. Additionally, tectonic activity and shifting landmasses may have played a role in the disappearance of some land bridges.
How are ice ages and interglacial periods related to carbon dioxide and temperature?
Ice ages and interglacial periods are closely linked to variations in carbon dioxide (CO2) levels and global temperatures. During ice ages, CO2 concentrations are generally lower, which contributes to cooler global temperatures and the expansion of ice sheets. In contrast, interglacial periods feature higher CO2 levels, leading to warmer temperatures and the melting of ice sheets. These fluctuations are influenced by natural processes such as Earth's orbital changes, which affect solar radiation and subsequently impact CO2 levels and climate.
What is an interglacial period?
An interglacial period is a phase of warmer climate that occurs between two glacial periods during an ice age. During these intervals, ice sheets retreat, leading to rising sea levels and changes in ecosystems and biodiversity. Interglacial periods are characterized by milder temperatures and can last for thousands of years. The current interglacial period, known as the Holocene, began approximately 11,700 years ago.

Is the sea level higher or lower than it was in the geologic past?
Sea levels have fluctuated throughout geologic history, sometimes being higher and sometimes lower than they are today. During periods of glacial melting, sea levels were higher, while during ice ages, sea levels were lower due to water being locked up in ice sheets. Currently, sea levels are rising due to global warming and melting ice caps.
