which type of scientist would study the earth's atmosphere?
The cryosphere, or the Earth's permanent and seasonal ice masses and their study through the science of glaciology, is sometimes considered to be part of the hydrosphere. Atmospheric sciences are those that study the Earth's atmosphere.
Earth scientists often conduct sophisticated computer analysis or go to many of the world's most exotic locations to study Earth phenomena (e.g. Antarctica or hot spot island chains). A foundational idea within the study Earth science is the notion of uniformitarianism.
