changes with climate patterns‚ soil type‚ wildfire regime‚ and other habitat characteristics. The near desert conditions in this area are moderated by the cold Pacific Ocean‚ which supports the dense chaparral vegetation. The rocky mountains of the Santa Barbara community contain a lot of vegetation that has to be well adapted to short rainy seasons‚ and hot‚ dry summers. Many species of small mammals‚ birds‚ snakes‚ and lizards live in the chaparral community. The chaparral is a dense forest of plants

Peterken (1981 and 1993) who used the basis of Tansleys’ system‚ but concentrated more on the management and stand mixes‚ coming up with 89 ‘semi-natural ancient woodland’ stand types and sub- types (Peterken 1993). This was replaced by National Vegetation Classification (NVC) in 1991 which rather than just looking at the main stands incorporates all the woodland layers classifying them into communities. The NVC was commissioned by the Nature Conservancy Council in 1975 and divides woodland and scrub

1) Cracks due to moisture changes. 2) Cracks due to temperature variation. 3) Cracks due to elastic deformation and creep. 4) Cracks due to effect of chemical reaction. 5) Cracks due to movements of ground. 6) Cracks due to vegetation. The various causes of formation of cracks and measures adopted to prevent them are described below: 1) Cracks due to moisture changes.

2005) The Effects Of Desertification -Soil becomes less usable The soil can be blown away by wind or washed away rain. Nutrients in the soil can be removed by wind or water. Salt can build up in the soil which makes it harder for plant growth. -Vegetation is Lacked or Damaged Loosened soil may bury plants or leave their roots exposed. Also‚ when overgrazing occurs‚ plant species may be lost. -Causes Famine Places that have war and poverty are most likely to have famine occur. Drought and poor

Hydroelectric power: The World’s Established Renewable Energy Resource For over a century‚ hydroelectric power has been used to generate electricity from falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Hydroelectric dams create height for the water to fall and provide storage. In general‚ the higher the dam‚ the more potential energy is available. Building up behind a high dam‚ water accumulates potential energy. The

Landforms by Erosion (erosion is the main process) * High-energy waves * Rocks that are easily eroded 1) Cliff and shore platforms Point : A cliff is a high‚ steep rock face along the coast. Explanation: A cliff is formed when waves repeatedly pound against a rocky coast Elaboration: This weakens the rock‚ causing the lines of weakness to form in the rock face * Over time‚ the waves erode the coast to cut a notch along the lines of weakness. * The notch may be further

subtracted from the wet temperature. The result of this subtraction was then interpreted by using a table and this determined the humidity. The light was measured in a spot where there were vegetation which had leaves and long trunks. This was done to observe how much light could penetrate through the vegetation. A light meter was obtained and it was turned face down in a spot were there was moderate light to ensure a fair result. The light meter then showed the light intensity in units of flux. The
