Vocabulary 7.1 System is a group of parts that work together as a whole. A group of related parts that work together to perform a function or produce a result. Energy- the ability to do work Atmosphere- The relative thin layer of gases that form Earth’s outermost layer. Geosphere- the densest parts of Earth, that include the crust, mantle and core. Hydrosphere- the portion of Earth that consists of liquid water, including oceans, glaciers, rivers, lakes, groundwater and water vapor. Cryosphere- the portion of Earth that consists of water in the form of ice, including glaciers, snowfields, sea ice and frozen ground. Biosphere- the parts of Earth that contain living organisms.

What are the Main Parts of the Earth System? Pg. 230 A system is a group of parts that work together as a whole. The Earth system involves a constant flow of matter though different parts. The constant flow, or cycling, of matter through the Earth system is driven by energy. Energy is the ability to do work. The energy that drives the Earth system has two main sources: heat from the sun (flowing in) heat flowing out of Earth as it cools. (flowing out)

The Earth system has five main spheres: Earth as a System The Earth system has five main spheres: The sun is a major source of energy for Earth processes, the sun can be considered part of the Earth system as well.

Spheres Overlapping The four spheres overlap, or interconnect. For example, a penguin, like all other living things, lives in the biosphere. But it breathes the air of the atmosphere and stands on the frozen water of the hydrosphere.
