(a)Lst five landforms found in the upper course of a river. (b) Highlight three differences and two Similarities between an alluvial fan and a delta.

(a) In the upper course of a river, some of the landforms that can be found include:
V-shaped valleys: These are narrow and deep valleys with steep sides formed through the erosive action of the river.
Interlocking spurs: These are hills or ridges of land that jut out into a river valley, and they form when the river erodes the land around them.
Waterfalls: These are steep drops in the river's course, formed when the river flows over a layer of hard rock.
Rapids: These are sections of a river where the water flows rapidly over rocks, creating turbulence.
Gorges: These are narrow, steep-sided valleys with a river at the bottom, formed by erosion from the river.
(b) Alluvial fans and deltas are two landforms that are formed by the deposition of sediment carried by a river. Here are some differences and similarities between them:
Differences:
Location: Alluvial fans are usually found at the base of mountains, while deltas are located where rivers meet the sea or a lake.
Shape: Alluvial fans are fan-shaped, while deltas are often triangular.
Material: Alluvial fans are composed of coarser sediment, while deltas are made up of finer sediment.
Similarities:
Both alluvial fans and deltas are formed through the deposition of sediment carried by rivers.
Both landforms are often characterized by the presence of multiple channels or distributaries, through which the river flows and deposits sediment.
Overall, while both alluvial fans and deltas are formed through the same basic process of sediment deposition by a river, their location, shape, and composition can differ significantly.
