ACROSS 

 

5. Having a wavelength just greater than that of the red end of the visible light spectrum but less than that of microwaves.

7. The Earth’s surface temperature is rising as a result of the increased amount of gasses in the atmosphere called greenhouse gasses.

8. The process where plants make food, such as glucose or carbohydrates, using carbon dioxide, water, and sunlight.

11. The regions of the surface, atmosphere, and hydrosphere of the earth occupied by living organisms.

12. A group of atoms bonded together, representing the smallest fundamental unit of a chemical compound that can take part in a chemical reaction.

15. The process where plants and animals convert carbohydrates, water and oxygen into energy. Water and carbon dioxide are released through this process.

17. Studies the earth's atmosphere, including Earth’s climate and weather. They develop reports, forecasts, and climate change research from their analysis of weather and climate data.

19. Radiant (electromagnetic) energy from the sun. It provides heat for the Earth and energy for photosynthesis. This radiant energy is necessary for the Earth and its inhabitants.

20. The distance between successive crests of a wave, especially points in a sound wave or electromagnetic wave.

DOWN

1. Amount of carbon exchanged between the Earth's carbon pools.

2. The effect of different gasses within the atmosphere reflecting radiant energy back to the Earth’s surface. This is similar to the effect which happens in a greenhouse.

3. Relating to, producing, or employing ultraviolet radiation.

4. Gasses in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat the sunlight brings from leaving the atmosphere. The main gasses are Water vapour, Carbon dioxide, Methane, Ozone, Nitrous oxide, and Chlorofluorocarbons.

6. The curved path of a celestial object or spacecraft around a star, planet, or moon.

9. The layer of air or gasses that surround the Earth. It is 78% nitrogen, 21% oxygen, 0.9% argon, and 0.03% carbon dioxide with other small percentages of elements. It also contains water vapor. It can be thought of as a protective coating of Earth. The atmosphere surrounds Earth, allowing for life to thrive on Earth. This keeps the planet warm and provides oxygen. This is also where the weather of Earth takes place. There are six layers. It is about 300 miles thick.

10. Combustible materials found inside the Earth’s crust which are remains of prehistoric organisms. Examples are natural gas, oil, and coal.

13. reservoirs of carbon which are able to take in and release carbon. Examples of this are oceans, terrestrial ecosystems, the Earth’s crust, and the atmosphere.

14. Protect something by using material that prevents the loss of heat or the intrusion of sound.

16. The act of releasing a substance into circulation making it available for chemical reaction.

18. Energy derived from the sun in the form of solar radiation.
