The waves are becoming higher as wind is also more intense. Tasmania is one of the places in which waves are increasing the most.

Most weather forms over the water, esp. in islands such as Australia/Tasmania. The wind interacts with the oceans to regulate the world's climate. It is cooler if storms form in deeper water as water can absorb more energy from the atmosphere.]]> 2016-08-28 23:58:08 UTC https://padlet.com/thomas_powell_davies18/pwehttfpu9gu/wish/120205285 thomas_powell_davies18 https://padlet.com/thomas_powell_davies18/pwehttfpu9gu/wish/120206559 Some of the things that need to be done are more vegetation of coastal areas. The roods of the vegetation will help to hold the sand together a bit more and hopefully then erosion will have a slightly lesser effect.]]> 2016-08-29 00:13:35 UTC https://padlet.com/thomas_powell_davies18/pwehttfpu9gu/wish/120206559 thomas_powell_davies18 https://padlet.com/thomas_powell_davies18/pwehttfpu9gu/wish/120207157 Longshore drift is when waves don't directly hit the coast on a perpendicular angle but are blown over to one side by the wind.

A wave is called destructive when it pulls away more sand that it deposits.
