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.

There are often (in fact usually) parts of electrical appliances which are not under voltage and play no part in the electrical functioning of the appliance.nside the appliance the earth wire is connected to the body of the appliance. It provides safety. So if there is a short circuit or some current leaks intot he body of the appliance the same is transmitted tot he ground thru the earth wire.
