Impacts of sea level rise on the Reef. Rising sea levels will be significant because much of the Great Barrier Reef coastline is low-lying. Predictions of a future increase in sea levels are highly variable and range from 0.68m across the Great Barrier Reef Region to a global increase of up to 0.9m by 2100.hanges in sea levels from temperature increases are time-dependent and uncertain, because they are partly linked to the collapse of the Earthâs great ice shelves. Since 1959, records of variations in sea levels for Townsville, in north Queensland, show an average increase of 1.2mm per year.
The earth wire is a crucial part of the home electrical system and is designed to protect against electric shock. If faults occur in the electrical system, the electricity will flow to earth by the shortest and easiest path.
Best Answer: The earth wire is better known as a protective conductor it provides a low resistance path for fault currents to flow. All exposed metal parts of any electrical system or equipment are connected to earth by a circuit protective conductor.ut .... if the Earth wire which comes in to your house is connected to the equipment's case and other conducting parts there can be no voltage present on the the case in the event of an fault. A Line wire touching the case would be, through the Earth wire, almost a short circuit across the supply.
