How are waterfalls?
The flowing water falls on the soft rock below, it wears it away and hard rock from the top of the water fall falls on the soft rock, as the hard rock falls from the top, it leaves a dent and the water wears this away, then pushing the waterfall back, wooop woopA waterfall is formed when there is a layer of hard rock and a layer of soft rock. The soft rock is eroded away first, so that the harder rock just hangs over, creating a waterfall.

Point where river waters flow from hard rock of the Piedmont to the soft rock of the coastal plain?
fall line
What are the processes of erosion that wear away the soft rock?
Abration and corrosion.
Why is north wales an upland area?
North Wales is mainly upland because of the hard rock wich is built up on top of ach other (this is called Igneous rock), this is because of the hard rock does not wear away as easy as the soft rock (which is normally Sedimantary).
What rock type is in the River Tillingbourne?
Chalk, sands, clay, and glacial drift can all be found in an around the River Tillingbourne.

They play Rock music . -Yeah rock, and soft rock sometimes. Some of they're songs are This afternoon, far away, never gonna be alone, search them up and you'd probablly like them! ;)
What is Hard Rock and Soft Rock?
Hard rock is rock that doesn't wear away easily (resistant rock), therefore, soft rock is rock that does wear away easily. I.e. that is way the coast is so uneven, because it hasn't got resistant levels of rock being continuously hit by destructive waves.
What feature may form by erosion on a river where a layer of soft rock lies beneath a layer of hard rock?
This would be the classic recipe for a waterfall.
What is the soft layer of rock in the mantle?
The soft layer of rock in the mantle is called the asthenosphere. It is located beneath the lithosphere and consists of partially molten rock that allows for the movement of tectonic plates.
When a soft rock wears out it forms a drop called a?
Machine gun drop
What causes the waterfall?
Water falls over Hard rock. When it reaches the soft rock, the water starts to wear away the soft rock, this is called erosion. Over hundreds or even thousands of years, the soft rock is slowly eaten away or eroded and the river begins to cut down further into the soft rock. This makes a cliff over which the water can topple. Over time, the cliff becomes steeper as more soft rock is eroded, and deeper as bigger boulders come over the waterfall, and the ground gets beaten with more and more rocks until it creates a plunge pool. Some of the water goes under the waterfall and under cuts the soft rock. More of the hard rock begins to fall away and the waterfall slowly moves upstream.Water falls are formed when a layer of soft rock is under a layer of hard rock. The soft rock is eroded forming a plunge pool. The hard rock fall in the plunge pool. As this keeps happening both layers stay the same and the water falls to the rivers.Waterfalls are formed by erosional processes- Hydraulic, corrosion and attrition action. Waterfalls form where rivers meet a less resistant rock, after flowing over more resistant rock. The hard rock eventually collapses into the plunge pool at the bottom and the soft rock is eroded back.It all starts off on top of a high elevation, such as a mountain, and when it rains the water tumbles down the mountain or hill. Sometimes there is no path for the water to follow so it must fall of the cliff. There is a layer of hard rock underneath the water and soft rock underneath that. The soft rock erodes faster than the hard rock forming a curved ledge underneath the hard rock. A plunge pool would be formed at the bottom once the water had started tumbling down. After some time, the hard rock would erode too, pushing the waterfall upstream over years.Wherever rain falls the laws of gravity assure that one way or another it will try to reach the ocean. Normally it moves to lower ground by lines of least resistance ie trickle down, first small creeks and streams slowly gathering to meet in a valley to form a river and down to the coast. Sometimes the rainfall on rocky platforms or plateau's can not find a route down hill. This water will gather until there is enough to find the line of least resistance and cascade over the edge of the plateau in a water fall. Over the course of time the rain will gouge out a permanent watercourse at this point
