- 5. When _____________ ocean currents flow close to a warm land mass, a desert is more likely to form (p.23).
- 7. The most diverse ecosystem on Earth and is abundant in both animal and plant life (p.12).
- 8. New ways to manage farms through the use of water systems, contributed to the increased food production, known as the Green Revolution (p.34-35).
- 9. This part of a wetland is covered by water all the time, it produces organic matter which marine creatures feed off (p.16-17).
- 10. The name of a biome that is found in the coldest areas of the world, no trees grow here (p.12).
- 12. Moisture is returned to Earth from the sky, in the form of rain, hail, snow or sleet.
- 13. A threat to coral reefs caused by fossil fuels, chemical waste and agricultural fertilisers. This pollutes the sea (p.19).
- 15. A part of the coastal wetlands, it has a high level of salt concentration and is an area that provides decomposing plant matter for marine life (p.16-17).
- 16. A big concern for coral reefs as the increase in water temperature is bleaching the coral, turning it while and destroying the reef system (p.19).
- 19. The growing population and increased standards of living are affecting the world's environments. It is putting pressure on the Earth's __________, energy, water and other natural resources (p.28).
- 21. Clearing of forests to make way for farming or housing.
- 22. These trees live in shallow water and swamp land. They store water and release it slowly into the ecosystem and their roots protrude out of the ground to take in oxygen when the tide is in (p.16-17).
- 24. Maintaining and managing our resources and environments for future generations.
- 26. A factor that affects the make up of a biome and is the distance north or south from the equator of a point on the Earth's surface (p.22-25).
- 27. Number of biomes covered in Geography Alive textbook.
- 28. This type of irrigation has been modified to supply water and be distributed over the soil surface by gravity (p. 36).
- 29. This geographical concept is about using time to better understand a place, an environment, a spatial patter or a geographical problem.
Down
- 1. A type of traditional agricultural practice that the Huli people live by. The land is used for food production until its fertility declines; it is abandoned until it returns naturally (p.33).
- 2. A traditional agricultural food practice where a group of people have no fixed home and move according to the seasons, in search of food, water and grazing land (p.32-33).
- 3. The Revolution in the 1960's which saw a significant increase in agricultural productivity.
- 4. Australia's grasslands are under threat due to the growth and spread of cities and being used for livestock grazing (p.14-15).
- 6. Part of a wetland which is exposed for a short time when the tide goes out and used as feeding area for birds and fish (p.16-17).
- 7. An increase in crop yields was largely brought about by the use of this additional food source for plants (p.34- 35).
- 11. The three main staple foods of the world (p.30-31).
- 14. This type of development has caused a great threat to coral reefs as it requires land clearing and wetland drainage. This causes erosion (p.19).
- 16. A modified way to help food production. It is an artificial biotic environment to protect crops from heat and cold and pests (p.36-37).
- 17. This plays a significant role in determining climate and the makeup of biomes. Mt Kilimanjaro has a very high __________ at 5895 metres (p.22).
- 18. There was an increase in food production with the use of chemicals that keep bugs and diseases from destroying crop yields (p.34-35).
- 20. This biome is mainly inhabited by reptiles, grazing animals and ground-nesting birds.
- 23. A factor that influences climate and the development of biomes is the air movement, _________ is the side of the mountain that faces the prevailing winds (p.25).
- 25. A biome that covers about 3/4 of the Earth.
