While the main roads and shopping centres are relatively out of the way in Dee Why, that is not the case for Collaroy. Pittwater Rd runs parallel to the beach for over a kilometre, merely 120 metres from the shoreline. This leaves very little room on the eastern side of the road for construction. Yet buildings have still been erected with permission from Warringah Council, and this is where the real problem stems from; the fact that the initial sub-division was too close to the beach with properties extending into the active beach zone. The Flight Deck building, Collaroy In addition to the houses being unsafe to live in, they are also damaging the beach itself.
Tree To¬¬¬ps Valley Discussion Questions: 7/1/12 2) What factors would account for the differences in tree species from the higher elevations of Tree Tops Valley, where pine trees dominated, to the lower part of the valley, which seemed to be mostly broad-leafed trees? In the higher elevations pine trees dominated due to the type of soil and the amount of sunlight available for the trees. The lower part of the valley had small spring-fed streams interlacing the growth of broad-leafed trees. Also, it is too cold at higher elevations for broad-leafed trees to survive. The valley and surrounding hillsides included different species such as black walnut hardwoods, red and silver maple, beech, red and white oaks, sycamores, white ash, yellow poplar, black and pin cherries, and some softer wooded aspen, sweet birch, and American basswood (a.k.a.
Its state-of-the art digital communications equipment, night fighting gear, and doctrine were realistically evaluated in an Advanced War fighting Experiment against the NTC's vaunted Opposition Force (OPFOR). The AWE began on 15 March 1997. Training and Doctrine Command's (TRADOC) Joint Venture and Force XXI were the processes the Army used to create Army XXI, the force developed to be capable of victory in the following century. The 1st Brigade Combat Team (not to be confused with the modular brigade combat team) deployed with nearly 1,000 vehicles. There were 73 separate technology initiatives consisting of more than 5,000 new items: Appliqué, Precision Lightweight Global Positioning System, Enhanced Position Location Reporting System, Single Channel Ground and Airborne Radio System, Battle Command Information System, and 1,386 others.
The investigation took place at 3 specifically chosen sites where Oak trees, Quercus robur, acted as barriers to sunlight. This meant that nettles growing under branches weren’t exposed to sufficient sunlight in contrast to nettles growing outside the reach of branches. All other factors were controlled. Due to a restricted amount of time, it was assumed that the light intensities measured represented the average conditions at the site. Using systematic sampling to identify and measure the nettle leaves, a strong correlation between light intensity and nettle leaf length was found where nettles that were exposed to lower amounts of sunlight had greater lengths.
The tanks were also unwieldy to use as they were prone to getting stuck in the mud and breakdown, as well as being short-ranged and slow, travelling only 10 kilometres per hour. These first tanks had not been tested in trench conditions and were not developed enough. Over a third of the shells used were duds and did not explode on impact. However, the tanks were useful in gaining land and were very effective against machine gun fire as the infantry could follow behind it using it as a shield against the bullets. Later, at the Battle of Cambrai, they were to be used to much greater effect.
Like most foraging groups the Mbuti are mobile. The Mbuti move around mainly to allow an area to regenerate its resources. They make simple huts made with branches and leaves. This allows them to travel lightly and build in a day when they reach somewhere new. They don’t carry or have many of possessions because it is impractical when you live in one locale.
Ghana may also lack the infrastructure i.e pipelines for transporting water making it hard for investments needed to become industrialised therefore the reason why it's low ( less than 100 cubic meters pp) Egypt although being part of the Sahel region uses a significant amount of water. Mainly for the agricultural sector (800 cubic meters pp). Egypt is under physical water stress and is arid so lack water. Most of the water is used for irrigation of crops that are impossible to grow in the natural conditions available. In conclusion water use varies due to many reasons it may be because of the climate in the area and also how developed they are.
Diet The main food that Koalas eat is eucalyptus leaves. Eucalyptus leaves are very fibrous and low in nutrition. Eucalyptus leaves contain a lot of water so koalas don’t have to drink. The koala’s metabolism rate is also regulated in a way to complement the heat insulation of the fur. The metabolism of the koala is quite slow it is only 74% of other animals’ metabolism rate.
Tropical Rainforests are located very close to the equator. Because of this, they don’t have seasons and receive between 406 and 1016 centimetres of rain every year. The weather is constantly warm, humid and rainy. There are four different layers in the rainforest. The forest floor – the ground, contains tree stumps, bases and fallen trees, the understorey – made up of small trees, vines and epiphytes, the canopy – a thick level made up of treetops that blocks sun from the levels below and the emergent – made up of trees that grow above the canopy layer.
Plant life As much of the Amazon is unexplored, many of its indigenous plants and animals are unknown. Plant growth is dense and its variety of animals inhabitants is comparatively high due to the heavy rainfall and the dense and extensive evergreen and coniferous forests. The forest cover is in fact so thick that a dense "roof" is created by the leaves and branches, which does not allow the sunlight to reach the ground. The ground remains dark and damp and only shade tolerant trees and vegetation will grow here. Orchids and bromeliads exploit trees and other plants to get closer to the sunlight.
