the coastline. To prevent this problem and minimize storm surges having such a large impact and causing severe damage to the coastline‚ rock revetments can be placed on South Cronulla beach (parallel to the beach and the coastline and in front of the dune system). Behind the rock revetments sand bags can also be placed‚ as sand bags absorb the water and they will act like a line of final defense when extreme waves are in action. Rock revetments are designed to reduce the impact on erosive power coming

water. Firstly‚ desert areas are composed of sand and the weather is extremely windy while glacial areas are cold and composed of water that is a thing a desert land is short of. Erosion performs a large role in both areas because wind erosion is liable for the way the rocks and sand dunes in a desert landscape are formed and water erosion is liable for the form of the glaciers in the glacial area. Though the desert area is a dry weather‚ water erosion can also perform an essential part in transforming

What is meant by dissolution? Dissolution is the action of being dissolved. 3. What kinds of rock are most susceptible to solution processes? Why? Limestone and dolomite are most susceptible to solution processes because the water‚ which is slightly acidic

natural accretion-erosion cycle is a geographical process caused by waves. The accretion-erosion cycle is caused by destructive and constructive waves. Beaches undergo submersion as a result of destructive waves‚ and accretion as a result of constructive waves. Submersion is where sand is moved from the visible part of beach to a submerged nearshore region. Accretion is when the sand moved during submersion is moved back to the visible section of beach. This is known as the accretion-erosion cycle. Longshore

We can tell this by carrying out specific research (secondary data) on different types of media and internet use. We can use GIS and Google earth to go back in time using the historic button and measure using the ruler button how the blowout of the sand dune has grown over time. Or simply

OCEANS AND THEIR COASTAL MARGINS: Distributions of oceans and ocean currents Distribution and Importance of Oceans: Oceans cover about 70% on the earth’s surface Great importance to humans in number of ways‚ include: regulating global climates and as a source of economic materials. Oceans are also important for leisure and recreation Oceans cover about 50% of the earth’s surface in the northern hemisphere and about 90% in the Southern hemisphere Ocean / Sea Area in 1000km^2 Pacific

tides and currents. At Narrabeen‚ the sediment is moved northwards towards the lagoon entrance. When large amounts of sediment drifts to the lagoon entrance‚ blockages occur. These blockages prevent water from entering or leaving the lagoon as the sand bar is higher than the water levels. Poor water quality can be a result of these blockages as run off from housing pollutes the water in the lagoon and if it can’t wash out to see due to the block‚ the quality for the water drops.

The rain does percolate through the sand into the islands water table. Underground water supplies are extensive; so much so that large amounts of water flow have literally formed the swamps on the island. North Stradbroke Island has been formed by large quantities of sand which have their origin in the rocks of the Great Dividing Range which became
