Ice cores drilled through the thickest glaciers at Earth's poles show the layers of snow that were deposited each season kind of like tree rings. The deepest layer in the deepest ice core is the oldest and in Antarctic, continuous ice cores date back at least 750,000 years.
Gases and particles of dust trapped in the snow forming the layers in the cores continuously preserves samples of the atmosphere and these can be analyzed to provide a record of the climate prevailing as each layer was deposited.

Why is sedimentary rock important in the study of earth's history?
Sedimentary rock provides evidence of the history of rock. But how? It's very simple. There are different layers of earth piled on top of each other. They may contain fossils or other organic materails. Scientists study the layers of the Earth and do that by looking at the soil and rock. The type of sediment in different layers will, of course, be different. Therefore, scientists can figure out about the type of year or years that the occupants of the Earth had.
