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.
Relevance. Rating Newest Oldest. Best Answer: - the earth wire is connected to the metal casing of an appliance. - if a live wire becomes loose and touches the casing a momentary large surge of current is drawn from the live wire and goes through the earth wire to the earth so that nobody gets hurt by an electric shock.- the large surge in current also blows the fuse.he Neutral wire provides the return for the circuit but the Earth wire is the secondary return should a fault develop to protect the user and normally connected to ground via metal parts of the appliance.
