Soft rock: Sandstone
The one where that one hott dude from heaven landed!!! :)
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.

Well a normal waterfall is formed from hard rock being at the top of the falls. Beneath this hard rock, is softer rock. When the water falls off the edge of the hard rock, the hits the bottom; this is called a plunge pool. The plunge pool is also made of soft rock. When the water hits the plunge pool, some waters splahes back up and hits the back of the bottom of the falls, eventually, this wears away at the bottom making an indentation, this process is called undercutting. So when the water flows over the hard rock at the top, it doesn't erode away as fast as the soft rock, if it did, it would just slope and looks like a river, this is what makes waterfalls so magnificant. So when the water from Angel Falls flows over the edge, its a free fall, this means that it doesnt hit the side of the waterfall. So once it has hit the bottom or the plunge pool, it slowly erodes. Over a long period of time, the plunge pool will get deeper and deeper. Here is an image from the web, it explains it alot easier, So type in Angel Falls.
Marble is a hard rock. it is a soft rock then the Taj Mahal situated in agra will have broken into peices.

Hard rock, an example of soft rock is Barton-on-sea.
Igneous rock is considered "hard" rock by geologists due to its interlocking crystalline structure.
Hard engineering :)
