Examples of weathering: - Mass movement is the movement of sediment down slope en mass. However, once the snow melts you generally will see a steep rising limb as the water suddenly melts and often cannot infiltrate as the ground below is still frozen.

This journey can be seen through the long profile of a river which is split into three sections, upper, middle and lower course.

We can use hard engineering, such as sea walls or soft engineering, like beach nourishment. The changing shape and height of the salt marsh forms bands of different types of vegetation, this is known as a vegetation succession.

This means more complex flowering plants can take over the pioneer species such as Sea Lavender and eventually trees and shrubs can grow such as ash and alder.

More Carbon Dioxide is produced because Variety is the Spice of Life. This is different to the other advice mentioned here as it encourages you to try a few different things to see what fits for you. It could have been caused by: They form in the sheltered area behind spits.

However, once the snow melts you generally will see a steep rising limb as the water suddenly melts and often cannot infiltrate as the ground below is still frozen.

The notch continues to get bigger until it can no longer support the material above and it collapses. Size of the basin - the larger the basin is the longer it will take the water to reach the trunk and therefore the lag time will be longer. They tried to live as they did in Norway and Iceland.

The mudflats are the lowest part f the salt marsh and are inundated with water on a regular basis. The UK is affected by five air masses The prevailing winds from the Atlantic Ocean in the south west.

When this stopped because of sea ice they had no one else to turn to. Create or join online study Groups and connect with thousands of GCSE students in any all of the subjects you are studying. They do this my monitoring seismic activity earthquakesthe use of tilt meters to monitor the shape of the mountain, use of chemical sensors to monitor sulfur gas levels and thermal imaging to detect heat around the volcano.

Spots mean greater activity and more solar energy being sent toward the Earth, making it warmer. The eroded material from the cliffs is deposited over time to form beaches. Over time the arch will get bigger and will not be able to support itself and due to gravity will collapse forming a stump.

Precipitation event - If the precipitation event is a snow event the lag time will be very long as we have to wait for the snow to melt. You can see an image of the drainage basin below.

When the snow melts, small plants flower. ReOrder Drag and drop a list of items, processes, or events into the correct order. The Earths axis also moves and wobbles about affecting how much sunlight is recieved.

The waves through the processes of hydraulic action, abrasion and solution erode cracks and weaknesses in the cliff face making them bigger, this forms caves.

If the basin is made from an impermeable rock such as granite the hydrograph will be much more flashy as the water will move quickly as surface runoff into the river.

Try these free student apps we recommend. This journey can be seen through the long profile of a river which is split into three sections, upper, middle and lower course. Rivers begin in upland areas and make their way to the see draining all the precipitation from that area.

Exclusion zones were set up and a hazard map created, these are still in effect today. Our example is Spurn Point.
