Answer:
glaciers covered better part of North America including California and it's still evident in San Bernardino Mountains.
Explanation:
The Pleistocene Epoch is typically defined as the time period that began about 2.6 million years ago and lasted until about 11,700 years ago. The most recent Ice Age occurred then, as glaciers covered huge parts of the planet Earth.
Sometimes, up to 30% of Earth was covered in ice. At times this included the better part of North America — California became almost completely entombed in ice. Today, evidence of the glacial takeover can be found as far down as southern California's San Bernardino Mountains.
The variation of sunlight reaching Earth is one cause of ice ages. ... When less sunlight reaches the northern latitudes, temperatures drop and more water freezes into ice, starting an ice age. When more sunlight reaches the northern latitudes, temperatures rise, ice sheets melt, and the ice age ends.
The doctrine of popular sovereignty was used. That meant that people in those states could choose to vote to support slavery and since they were majority then slavery would be permitted. There were even states that were at first non-slave states but then things changed and they voted to introduce slavery into the state and people voted for this and supported this.
