Studying earth's layer's is important. It gives us an insight about how the atmosphere works.
It's what we live on.
How hot it is and how much it weighs.

Sorry, but I do not understand "eaths". You should have spell-checked the question before posting it.

The layers of the Earth provide valuable insight into its composition, structure, and history. By studying these layers, scientists can understand phenomena such as plate tectonics, volcanic activity, and magnetic field generation. Additionally, these layers are crucial for interpreting geological events and predicting natural disasters.

ice layers are so important to know because describes the history of the ice layers. so scientist can study the ice layers.
The geologic law that scientists use to date the crust by studying the layers of rocks is the Law of Superposition. This law states that in a sequence of undisturbed rock layers, the oldest rock layer will be at the bottom and the youngest will be at the top. By studying the relative positions of these rock layers, scientists can determine the relative ages of the rocks.

Troposphere (the Eaths surface to around 30,000-56,000 ft) Stratosphere (from the tropopause to 170,000 ft) Mesophere (from the stratopause to 260,000-280,000 ft) The layers above are considered "the three main layers". Thermosphere (the deviding between the Thermosphere and the Mesophere iis known as the turbopause, it is air that is poorly mixed. The height is around 1,100,000-2,600,000 ft) Exosphere
