Name two types of submerge coasts

1/3/2021

KCSE Geography Paper 1 2001 Section B Question 8.

(a) Name two types of submerge coasts

Fiord/ fjard/ fyord
Dalmattan / Longitudinal
Estuarine
Ria

(b) Explain how the following factors determine the effectiveness of wave erosion along a coast
(i) Nature of the material transported by waves

Hard rocks carried by waves increase the erosive power of the waves as they hit against the coast
Heavy pieces of rocks carried by waves hit against the cliffs thus weakening the wall making it susceptible to wave erosion

(ii) Nature of the coastal rocks

A coat made of soft rocks wears away easily when subjected to sea waves
Well jointed / fractured/ unconsolidated rock enhances erosion by waves along the line of weakness
Where rocks are soluble or made of limestone/ chalk they are easily eroded through solution process

(c) With the aid of labeled diagrams, describe the process through which a stack is formed

(a) Name two types of submerge coasts (b) Explain how the following factors determine the effectiveness of wave erosion along a coast (i) Nature of the material transported by waves (ii) Nature of the coastal rocks (c) With the aid of labeled diagrams, describe the process through which a stack is formed (d) (i) State four conditions that favour the growth of coral (ii) Explain three ways in which coral contributes to the economic development of Kenya.

Use the map of North-West Atlantic below to answer questions (a) and (b).

Use the map of North-West Atlantic below to answer questions (a) and (b). a) i) Name the country ii) Explain how the two ocean currents shown on the map influence fishing in the area shaded on the map other than ocean currents. b) Explain three factors that favour fishing in the area shaded on the map other than ocean currents c) Explain why in East Africa, fresh water fishing water in the area shaded on the map other than ocean currents.

Use the map of North-West Atlantic below to answer questions (a) and (b). a) i) Name the country ii) Explain how the two ocean currents shown on the map influence fishing in the area shaded on the map other than ocean currents. b) Explain three factors that favour fishing in the area shaded on the map other than ocean currents c) Explain why in East Africa, fresh water fishing water in the area shaded on the map other than ocean currents.

a) i) Name the country

Canada

ii) Explain how the two ocean currents shown on the map influence fishing in the area shaded on the map other than ocean currents.

The convergence of the warm and cold currents causes upwelling of ocean water which bring minerals for planktons to the surface attracting large number of fish to the area
The convergence of warm and cold currents modifies the temperature of the ocean water making the area ideal for fishing throughout the year
The cool waters favour survival of a wide variety of fish species which makes the area an important fishing ground

Describe the process through which a crag and tail is formed.

i) Name the features marked M, N, and P.

H: Trough
J: Crest
K: Swash

ii) Describe the process through which a crag and tail is formed.

It is the return flow of water down the beach to the sea after a wave has broken.

A weak backwash strong swash/constructive waves
Gently sloping land at the sea shore

What are tides?

9/2/2021

KCSE Geography Paper 1 2011 Section B Question 9.

(a) (i) What are tides?

Tides are the periodic rise and fall in the level of ocean/seas/large lakes as a result of the gravitational attraction of the sun and moon.

(ii) Give three causes of ocean currents.

Differences in ocean water density/salinity.
Differences in ocean water temperature.
Winds blowing over the ocean.
Shape of coastal land mass.
Rotation of the earth

(iii) Name the three ocean currents along the western coast of Africa.

Benguela
Guinea
Cannary.

Identify the main characteristics of the ocean water.

27/1/2021

KCSE Geography Paper 1 2018 Section A Question 4.

(a) Identify the main characteristics of the ocean water.

Ocean water is saline/salty.
The temperature of ocean water varies horizontally and vertically.
Varies in density
It is in constant movement

16/1/2021

KCSE Geography Past Paper 1996 Paper 1 Qn3.

a) List four processes through which costs are eroded (4mks)

By hydraulic action
Abrasion / currasion
Solution / Currasion

b) Using well-labeled diagram, explain how each of the following features is used formed.

i) A spit (4mks)
ii) A blow hole (2mks)

i) Formation of a spit.

It forms on a shallow shore at a point where there is a change in the angle of the coastline.
Sand or shingle is deposited by long shore drift / oblique waves
Deposition continues and materials accumulates seawards
With time, an elongated feature with one end attached to the mainland projects into the sea and it called a split
