Answer 2

The falling stream of water from a height is called a waterfall.

Explanation:

• The falling stream of water from a height is called a waterfall.
• Waterfall occurs at places where the stream profile makes a vertical drop.
• Such situation is usually found where gently inclined,erosion resistant beds overlie the non-resistant beds.
• The softer rock is eroded first while the harder one offers resistance and form a ledge at a height.
• From this height, the stream's water falls  deep down into the gorge.
• When the water falls over the ledge, it erodes the less resistant beds of the cliff.
• Due to this undercutting a portion of the upper resistant bed breaks off and the waterfall retains its vertical cliff while it gradually moves upstream.
