   The physical geography of Australia varies depending on which part of the continent you reside. There are a few mountains in Australia, one range in particular are the Blue Mountains (as mentioned in my previous blogs.) This mountain range encompasses the Jamison Valley. Jamison Valley is formed by fluvial erosion thus creating the oblique on the valleys so that water can drain within the valley.



Jamison valley holds waterfalls and kickpoints ultimately depicting a break in slope for a stream to try and reach equilibrium. These kickpoints are temporary and due to the rising land and will eventually even out and create a flattened slope instead of jagged waterfalls. This could lead to the base level falling of the valley which is called incision. Due to the fact that Jamison Valley lacks a long river flowing through it the idea that the stream eroded remains present. This happens when the stream's energy is greater than that required to transport the sediment



Over the next ten years there will be little noticeable change to Jamison Valley, but the process of falling and base levels rising will be taking its toll on the kick points and waterfalls within the valley. Although, over the next one hundred years the kick points and waterfalls will begin to flatten and create a slope like look (as depicted in the picture above to the right.) This is due to the eroding of the rock thus creating the base levels to fall and allow for a less jagged hill side filled with waterfalls and kick points. This process of erosion and deposition will continue throughout time thus riding the land of waterfalls and kick points over the newt one thousand years. 


Another aspect of Australia's landscape is it coastal region. The tides that are created off the coast of Australia are due to the moon's gravity. These tides create refraction which means energy is concentrated and spread out along the coast. Erosional landforms are created through weathering over many years.The erosion from the water creates wave-cut notches and sea stacks. The formation of the notches forces the land to erode ultimately riding the land of these rocks. Over the next one thousand years the rocky slope that border the coast of australia are going to erode into nothing creating a flat surface on the coast.

The image below is of stratocumulus clouds. These clouds are cumulus clouds which means they are piled up and lumpy. The strata comes from the low level cloud classification which means they have a base of less than 2000 meters. 
The clouds in this picture (below) are called fair weather cumulus which means they are not clouds that collect precipitation before a storm. They are also cumulus because they are lumpy and piled up.

In this photo there is radiation fog which means the fog is close to the ground. When the ground chills air by conduction, dew point is reached and fog forms right above the ground. This is hazardous because it creates a thick, hazy air that prevents clear visibility especially while driving. 
In this photo (below) shows one state of water and that is liquid. In the ocean water is in its liquid form, but from heat the water turns into water vapor and evaporates into the air and forms clouds. This water vapor is gaseous and mostly invisible and compressible therefore it can be in any space like water, but is more compact.
