Across
- 1. the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules
- 4. first layer in the atmosphere and is 10km of atmospphere
- 8. rock that are formed by the accumulation or deposition of mineral or organic particles at the Earth's surface, followed by cementation
- 9. they are found on land and or underwater and get nutrients through photosynthesis
- 10. emission or transmission of energy in the form of waves or particles through space or through a material medium
Down
- 2. the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location
- 3. a chemical reaction that happens in all living cells, including plant cells and animal cells. It is the way that energy is released from glucose so that all the other chemical processes needed for life can happen.
- 5. a layer or a set of layers of gases surrounding a planet or other material body, that is held in place by the gravity of that body
- 6. microscopic marine algae
- 7. chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons
