Australia’s most precious landforms are its water bodies each of which has a very important role for the survival of life and vegetation in Australia. The two largest and most important water bodies in Australia are its large natural inland lakes and man made dams; both these landforms provide the essential

plant distribution For example the Palmae/Arecaceae are cold intolerant as their single meristem is susceptible to frost. Conversely‚ boundaries between vegetation types (e.g. Arctic treeline) are generally determined by summer warmth * Rainfall is also an important determinant: for example it affects the balance of grasses to woody vegetation * Other factors such as soil type or herbivory may also be affected by climate change.

temperatures never go above 45o or 50o F. In winter‚ temperatures don’t reach above 20o F and average between -20o to -30o F. Tundra biomes receive low levels of precipitation‚ around 150 to 250 mm of rain per year. Due to the harsh climate‚ vegetation such as low shrubs‚ sedges and reindeer mosses have adapted by growing close to the ground and close together‚ as this helps plants to resist the effects of cold weather and reduce damage caused by snow and ice. Plants are also small and roots are

It almost feels as if the area on that side of the track is dead with no vegetation surrounding it. The other side of the track has lots of vegetation; there are trees‚ fields of grain‚ and a river.

permafrost‚ which means it has a thick layer of frozen soil throughout the year. The latitude of the tundra is 66.5625 degrees north‚ 0 degrees east. The tundra does not have many types of vegetation. It has shrubs‚ grass in some parts and a lot of mosses. The tundra is too cold to be able to grow a lot of vegetation. The animals that live in the tundra are the arctic foxes‚ musk ox‚ the snowy owl‚ lemmings‚ and the polar bear! One of the animals that live in the tundra‚ the snowy owl‚ is very interesting

Land degradation will remain an important global issue for the 21st century because of its adverse impact on agronomic productivity‚ the environment‚ and its effect on food security and the quality of life. Productivity impacts of land degradation are due to a decline in land quality on site where degradation occurs (e.g. erosion) and off site where sediments are deposited. However‚ the on-site impacts of land degradation on productivity are easily masked due to use of additional inputs and adoption

West Africans developed their knowledge of tropical climate over many years and were able to make the leached soil of the Niger Delta profitable for themselves. The agricultural revolution in West Africa lead towards the Atlantic Slave Trade. The agricultural skills and knowledge of West Africans attracted Europeans. West Africans’ tropical agricultural skills greatly interested outsiders because the Europeans wanted to profit from this knowledge. On the map it is shown that West Africa consists

definition of a landslide is: A gravity driven down slope movement of a mass composed of soil‚ rock‚ and vegetation. A landslide generally happens when the material in the down slope is heavier then the supporting soil. There are many contributing factors that cause landslides‚ steepness of slope‚ composition of soil and rock‚ groundwater condition‚ recent precipitation patterns‚ slope aspects vegetation on slopes‚ and anthropomorphic activities (land clearing). There are generally four types of landslides;
