The layers in an ice core sample shows the different levels of matter (gasses, dust, etc) that were present in the earth's atmosphere at any stage in the past hundred thousand years. Each layer will be different according to how much gas or dust was in the atmosphere when the ice froze (trapping the gas and dust inside). These gas levels can be used for further research into issues like climate change.
Scientists theories lead to knowing that Earth was made up about 5 billion years ago. The sun was a swirling cloud if gas and dust. Soon the cloud started to flatten out. then hydrogen and helium filled up the flat cloud and our sun was born. the planets formed from the left over matter.
