21. The figure below shows
a local physical feature, name it and explain its formation.
| Suggested Answers:
B is a dyke
The formation of B
Dyke, as a form of occurence of the hypabyssal igneous rocks, is a sign of igneous activity. "With the release of crustal pressure, the molten magma fills the vertical joints or faults in the earth crust, and is solidified at last when cooled. As it is a mass of intrusive rock which cuts discordantly across the bedding planes of the parent rock, there may be a marked difference in their fesistances. When affected by denuation, it will either stand up as a ridge (where the dyke rock is more resistant than its adjacent ro rocks) or be worn away to
form furrow (where the dyke rock is less resistant than its adjacent rocks).
22. Describe the main
characteristics of the physical landscape of a delta. Explain fully the formation of a delta. Suggested Answers:
„Main Characteristic Features
Of Delta:
A delta is a lowlying swampy plain built up at the mouth of a river by its deposition. It is crossed by numerical levee-flanked distributaries. Remnants of the lagoons and marshes formed in its early stage can be found. The seaward edge

班
of it is fringed by spits and bars. The shape and size of a delta vary according to the amount and type of loads deposited and the mode of accumulation. The common
shapes of deltas are arcuate, bird's foot and estuarine. Formation:
When a stream flows into
a body of standing water, such as a lake or an ocean, its velocity and transporting power are quickly steamed. If it carries enough load and if the estuary it enters is shallow and free from tidal current or strong ocean current, a delta will gradually
be built. The stages in the
formation and development of
a delta can be summerised as follow:
Stage I:
At the estuary, abundant loads are dropped. These loads will be coagulated when they are in contact with sea water. The river is thus choked and therefore branches out into several distributaries, Spits and bars arise and lagoons are formed. The levees of the river extends extend seaward via the
distributaries.
Stage II:
When more sediments are deposited, the lagoon will be, gradually filled, and they become swampy. The delta begins to assume a more solid appearance.
Stage III:
The old part of the delta is slowly raised by further deposition with the aid of the colonization of vegetation. Swamps gradually disappear and this part of the delta becomes dry land.
