Uluru (Ayers Rock) – is the remains of the weathering of a large granite mountain range (about the size of the Himalayas) that with wind and water eroded quickly as their was no plant life and formed an alluvial fan near its base. One fan on top of the other. It was then covered by an inland sea and the pressure turned them to arkose sandstone, a sedimentary rock. Another mountain building flipped the bedrock on its side and more weathering took place. It is amazing to think that like an ice berg there is more of this rock under the surface than there is on top.
Weathering of Uluru.
Water is a big weathering agent.
The abrasive action as the water washes over the particles smoothes any roughness out of them.
The Pasha Bulka didn’t weather the storm well and was washed aground on Nobbys Beach. They did eventually manage to refloat her.
This wharf didn’t weather the storm too well with major damage being sustained and boats no longer able to use it.
Will we weather the storm as our polar ice melts and sea levels rise?
Water carves out gullies
and huge canyons
with gravity assisting the water to carve out arches.
Not often can we see the effects of weathering before and after but at Lake Siwi on the Island of Tanna after a cylonic dump of rain
the lake is no more.
Weathering can affect man made objects too with paint peeling and fading
and structures crumbling.
Wind, moving water and gravity
But man he too plays a part
with animals, chemicals and what he plants
Our biggest threat to mankind
Is our changing climate
Extreme weather results
Our world erodes
Is it too late to stem the tide.
