Cold temperatures during the Late Pleistocene led to lower sea levels as a result of glaciers trapping significant amounts of wa
ter. This decrease in sea levels exposed landshelves and allowed modern humans to migrate to previously uninhabited continents. Identify the continents to which early modern humans were able to migrate due to low sea levels.
Africa to Middle east to Asia and to Oceania and then to Eurasia and to America.
Explanation:
The human migration started around 2 million years ago form the continent of Africa, the early humans crossed the land bridges that were covered by water.
The population of the early homo sapiens migrated to Europe between the 130,000 and 115,000 million years ago. Reaching china through the nile valley and heading to the middle east into modern Israel by the Strait on the Red Sea at the time sea level was much lower and narrow.
<u>The migration continued through Asia to the southeastern coast and entering the Australia 50,000 years ago. At the time of the last glacial maximum. Also, the coastal population around the southeast Asia grew with the dispersal of the humans giving rise to the old and the new world i.e America.
</u>
Paleo Indians emerged for central Asia crossing the Beringia land bridge between the eastern Siberia and present-day Alaska. Continued by the end of the last glacial peroid i.e 23,000 years BP.
if all glaciers melt, then sea level would increase and then the ocean will over up the whole earth or parts of it, so it is like a big flood all over the earth and it is too high.
<u>Inversion is found in upper layer sf troposphere.</u>
Explanation:
When there is a decrease temperature t every 3.5 degrees for every 100 feet. As when this normal cycle is present the air said to be unstable and constantly flows between the warm and cold areas.
During inversion temperature decrease with the increasing altitudes. temperature inversion can occur in areas of coastal origins due to the upwelling of cold waters.
Topography plays a role as cold and cool air flows from the mountain peaks down into valleys. This cold air then is pushed back due to the warm and lighter air mass and hence creating an invention.
Inversions can also form in areas with significant snow cover as the ground is cold white color reflects most of the sunlight.
