Global Systems

5. The measurement of weather patterns and averages of an environment/area over a period of time.
6. The water layer of the Earth consisting of all the water on Earth.
9. A term used to describe the constant circulation movement of the ocean which is influenced by the salinity levels and seal level temperatures.
11. A process of the water cycle in which water is heated by the sun and becomes water vapour.
13. fuel A fuel composed of stored carbon from the preserved bodies of dead organisms.
14. A greenhouse gas that is colourless and has a chemical formula of CH4.
16. A colourless gas that is a greenhouse gas forming most of the earth's atmosphere.
17. A major procedure that includes the clearing/logging of forests for urbanisation, farming land and wood uses.
20. A region of the electromagnetic spectrum of which the wave length is greater than the end of the red region but shorter than a microwave wave length.
21. The day to day conditions of an environment, it occurs in the troposphere.
25. The interaction of Earth's regions and all the living things in those regions.
26. Fuels composed of natural, organic material and matter.

1. A type of energy that is transmitted in waves and particles.
2. A wave length on the radio region of the spectrum that is long.
3. effect The process of thermal energy (radiation) absorbed by gases which emit the absorbed energy into the atmosphere which then warms the Earth.
4. The process plants use to convert the sun's light into chemical energy to create a sugar of which the plant can break down and use.
7. Regions of Earth where the ground level temperature stays below freezing point or at 0 °C.
8. The outer layer of Earth composing of the upper mantle and crust.
10. niño A phase of varying warmer weather conditions and patterns of ocean currents in the Pacific ocean causing over the average weather in many places.
12. A process within the water cycle in which water vapour turns into liquid.
15. A series of thin gas layers surrounding the Earth.
18. The interactions of organisms in a environment with the biotic and biotic factors of that environment.
19. Periods of warm and mild climate between glaciations that last for thousands of years.
20. sheet A layer of ice containing fresh water and it covers many regions on Earth and is formed through the build up of snow for millions of years.
22. The discharge of substance or gases into the environment and atmosphere.
23. Resources or methods that can be recycled and re used again without harming the Earth.
24. cycle The process of carbon recycled through Earth's environment.
