_Answer two questions only from this part_

The scale of the map is 1:50,000

Old scale/New scale = 1/2

1:50,000/x = 1/2
x = 1:50,000*2
x = 1:100,000

The New scale is 1:100,000


South West Direction

The drainage pattern is dendritic. It has many tributaries. River kunni is the major river flowing towards Northwestern direction

(ii) Water transportation




Sedimentary rock is a type of rock that forms at or near the Earth’s surface through the accumulation and solidification of sediment. Sediment can include pieces of other rocks minerals organic matter and even shells or skeletal remains of marine organisms.

(i) Clastic or detrital sedimentary rocks
(ii) Chemical sedimentary rocks
(iii) Organic sedimentary rocks

chemical sedimentary rocks: These rocks form when dissolved minerals in water undergo chemical processes such as precipitation to form solid rock. Examples include limestone dolomite and rock salt. Limestone is primarily composed of the mineral calcite which is derived from the shells of marine organisms such as corals algae and mollusks. It forms in shallow marine environments where the accumulation of organic matter and precipitation of calcite take place over long periods of time. Limestone often exhibits fossilized remains of ancient marine life making it valuable for studying Earth’s history and paleontology. Limestone is widely used as a building material for making cement as a raw material in manufacturing and for decorative purposes due to its durability and attractive appearance.

(i) Natural resources
(ii) Water storage and aquifers
(iii) Fossil fuels
(iv) Geological history and research
(v) Landscapes and tourism
(vi) Soil fertility


(i) Rainfall: Rain gauge or pluviometer
(ii) Humidity: Hygrometer or psychrometer
(iii) Temperature: Thermometer or temperature sensor
(iv) Wind speed: Anemometer

Check the diagram below

(i) Place the rain gauge in an open area away from trees buildings or other obstructions to ensure an accurate measurement.
(ii) Ensure that the gauge is level and stable to prevent any tipping or spilling of collected rainwater.
(iii) Read and record the initial measurement of rainfall on the graduated scale.
(iv) Leave the rain gauge undisturbed for a specified period (such as 24 hours) to collect rainwater.
(v) After the collection period carefully read the new measurement on the graduated scale.
(vi) Subtract the initial measurement from the final measurement to determine the amount of rainfall during that period.


Mass movement refers to the movement of large amounts of material such as soil rocks and debris down slopes due to the force of gravity. It is usually triggered by factors such as the slope angle water saturation of the material vegetation cover and human activities.

(i) Landslides: Landslides occur when a mass of rock soil or debris rapidly moves down a slope. There are several types of landslides including rockslides debris flows and slumps.
(ii) Soil Erosion: Soil erosion refers to the gradual removal or displacement of soil particles from the land surface. It can happen through various processes such as sheet erosion rill erosion and gully erosion.

(i) Rockslides
(ii) Debris flows
(iii) Slumps

(i) Sheet erosion
(ii) Rill erosion
(iii) Gully erosion

(i) Destruction of Infrastructure: Mass movements can damage or destroy roads buildings bridges and other infrastructure in their path. This can lead to disruptions in transportation utilities and communication networks.
(ii) Loss of Life and Injury: Mass movements can pose a significant risk to human life especially during sudden and rapid events such as landslides. People caught in the path of mass movement may be injured or even killed.
(iii) Loss of Property: Mass movements can cause significant financial losses by damaging or destroying residential and commercial properties. This can result in the displacement of individuals and communities.
(iv) Environmental Damage: Mass movements can cause severe environmental damage by altering ecosystems destroying habitats and reducing biodiversity. They can also lead to soil erosion and sedimentation in bodies of water impacting aquatic ecosystems.
(v) Soil Degradation: Mass movements particularly soil erosion can lead to the loss of fertile topsoil reducing the quality and productivity of agricultural land. This can impact food production and agricultural economies.
(vi) Disruption of Water Resources: Mass movements can affect water resources by altering drainage patterns and causing the formation of new channels. This can result in flooding increased sedimentation and contamination of water sources with debris and pollutants.
