Question 62 of 67
62. Question

Grading can be reviewed and adjusted.Grading can be reviewed and adjusted.Hint
(i.) Calculate the distance between Addis Ababa in Ethiopia (latitude 10°N) and Maseru in Lesotho (latitude 30°S). of the earth.
- Location of Addis Ababa is 100N
2. Location of Maseru in Lesotho is 300S
Difference in latitude between the two locations =100 + 300 = 400
Being that 10= 111km or 111.1km
400 = 111×40 = 4440km or 111.1×40= 4444km
(b.) (i.) define revolution of the earth
Revolution of the earth is the movement of the earth round the sun on its elliptical orbit under the period of 365⅟4 days.
(ii.) describe how revolution of the earth affects the length of day and night in the Northern Hemisphere.
- In the winter period, when the sun is at the tropic of Capricorn [December 22] the northern hemisphere witnesses increase in the length of day and decrease in the length of night
- On that day of December 22, the arctic circle never witnessed sun rise, therefore, there is complete darkness.
- During the equinox, there is equal length of days and night for both hemispheres and that is on March 21 and September 23.
- The variation in the length of day and night depends solely on the position of the sun in relation to the earth.
- As one moves towards the north pole, during the summer, the period of daylight increases.
- The region from arctic circle to the north pole during the summer is referred to as land of mid night sun.
- At this time the sun is over head at the tropic of cancer.

(a) With the aid of diagrams, describe the characteristics of any two of the following features: .
(i) meanders
- Meanders are formed when there is reduced velocity of rivers due to reduce slope
- The rivers are unable to move straight i.e. moves to winding form, along their channel.
- Meanders are found at the middle and lower courses of a river
- On the concave side deposition takes place
- It is also found where there is a wide flood plain.
(ii) flood plain
- Flood plain is made up of sediments deposited at the lowland areas of a river valley
- It is a gentle sloping plane of alluvial deposits covering the valley floor along which the river flows in meandering channel.
- It contains fertile soils for agriculture
- On plain, coarser materials are deposited before finer ones hence sorting takes place.
- It is usually found at the middle and lower courses of a river.
(iii) braided stream.
- Streams or rivers are said to be braided when they break up into channels and later rejoin and split up again.
- It is a feature of lower course of a river.
- The stream or river gets blocked as a result of sand deposit on the floor of the rivers.
- It is the deposit along the course of the river or stream that enforces the breakup of the river into channels that rejoin later t become braided streams.

(a)
(i). The hottest month = 480c
The coldest month = 100c
(b) (i) Annual range of temperature
temperature of the hottest month

(a) What is soil profile?
Soil profile can be defined as the vertical section of the soil as viewed from the surface down to the parent rock. It can also be seen as the vertical sectional arrangement of soil particles at various horizons or layers.
(b) Describe the characteristics of any three zones of soil profile.
The horizons are present; they are identified through colour, texture and physical constituents. The soil profile is usually with three horizons; A, B and C horizons
HORIZON A
- It is the topmost layer
- Rich in remains of plants and animals which form humus.
- A lot of biological activities take place in this layer.
- It contains micro-organisms
- It is the layer with a lot of plant roots
- For the humus content, it appears darker than other layers.
HORIZON B
- The horizon is referred to as the subsoil
- This is a zone where soil nutrients accumulate due to leaching from horizon A
- This zone is also called a zone of illuviation
- At this zone organic materials washed from horizon A are converted to inorganic compounds and rich in magnesium and aluminum
HORIZON C
- This is a zone of parent rocks
- Materials contained in zones A and B are formed in this zone.
- As one looks through this zone, the unweathered rocks are seen.
(b) Draw a well labeled diagram of soil profile.

Question 67 of 67
67. Question
(a) Define ecosystem
(b.) identify, with examples, two main components of the ecosystem.
(c) Describe the interdependence between two, main components identified in (b) above.
(d) In what two ways can environmental balance be achieved?

Grading can be reviewed and adjusted.Grading can be reviewed and adjusted.Hint
(a) Define ecosystem
Ecosystem can be defined as the community of plants and animals living together and interacting in their physical environment.
(b) identify, with examples, two main components of the ecosystem.
Ecosystem is structurally of two main components
- Physical or inorganic or abiotic components. Examples of this components are; climate; soil; drainage and other non-living substances within the environment.
- Biological or biotic components examples are plants and animals.
(c) The interdependence between the two components
- Support and nutrients which plants depends on come from the soil.
- Living organisms depend on air, soil and water for their existence
- Man carries out his activities on land
- Some gases like oxygen and carbon dioxide are made available to nature through respiration and photosynthesis
5. Decomposers or bacteria break down dead plants and animals to form soil
(d) In what two ways can environmental balance be achieved?
- Reforestation
- Hydrological cycle
- Carbon cycle
- Nitrogen cycle
- Mineral nutrient cycle
- Food chain and food web.
