Answer:

As the river erodes the landscape in the upper course, it winds and bends to avoid areas of hard rock. This creates interlocking spurs, which look a bit like the interlocking parts of a zip. When a river runs over alternating layers of hard and soft rock, rapids and waterfalls may form.

Answer:

Rapids form when there is vertical bedding which is when alternate bands of hard and soft rock cross the channel. Differential erosion will occur as soft rock is more easily eroded than hard rock. This makes the riverbed uneven and a river’s flow becomes turbulent leading to white water sections typical of rapids.

kodGreya [7K]

Answer:

The Carboniferous era had large deposits of coal matter in the soil. However there was absence of decomposers which gave rise to increased accumulation of organic matter in the soil.

Decomposers make use of oxygen to breathe in the soil due to their existence as animals and not plants. They inhale oxygen and give out Carbon dioxide.

Absence of these decomposers mean increased level of oxygen due to its non usage and reduction in CO2 which is the end product of respiration for the decomposers.
