Waterfall.
Because the large one has a more bigger surface than the small rock
The type of rock found at the top of a waterfall can vary, but it is typically igneous or metamorphic rock. These types of rocks are more resistant to erosion and can withstand the force of the water flowing over them.
Sedimentary rocks can wear away to form sediment through weathering processes such as erosion, transportation, and deposition. These rocks are formed from the accumulation and cementation of sediments over time.
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.
A waterfall. The softer rock erodes faster than the harder rock, creating a drop in the landscape as the water flows downstream. This process over time can lead to the formation of a waterfall where the softer rock has worn away.
it is a waterfall
Waterfall.
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.

A waterfall is created when a stream flows over erosion resistant rock that ends in a sudden drop or falling away.
by a high current that is from the sea in to a river and over time the rock has worn away by the water then a waterfall is formed with a very high current!
They are, all the time. Every waterfall moves upstream constantly (but slowly).
umm sedimentary
Constant erosion from wind and water makes the rock wear away. It's how canyons and mountains were formed.
Sometimes, a waterfall when a river flows from hard rock to softer rock. The softer rock, such as limestone, is easily eroded, or worn away, by the flow of the river.
Erosion can cause a waterfall to retreat upstream over time by wearing away the rock and sediment at the base, creating a plunge pool. The force of the waterfall can also erode the sides of the waterfall, creating a deeper channel and possibly changing the shape of the waterfall itself.
