The cryosphere is the component of the Earth that composed of all solid, frozen water found on Earth. The cryosphere includes water storage areas such as glaciers, iceburgs, snow-covered areas, and sea ice. The cryosphere expands and contracts over the course of the months as average temperatures across the globe fluctuate.
The ionosphere and the exosphere together make up the upper atmosphere (or thermosphere). The magnetosphere is the region above the Earth's surface in which charged particles are affected by the Earth's magnetic field. Another well-known layer of the atmosphere is the ozone layer, occupying much of the stratosphere. This layer is defined by its chemical composition - where ozone is especially abundant. The lowest layer of the atmosphere is called the troposphere. It ranges in thickness from 8km at the poles to 16km over the equator.
