Step-by-step solution

9 steps

Part a

On the map extract, draw a linear scale bar for 1:50 000 (e.g., 0→1→20 \to 1 \to 2 km) using a red pen. Include a key showing symbols such as ∙\bullet for trig beacons, solid blue line for perennial rivers, dashed line for seasonal rivers.

Part b(i)

Secondary roads: Drawn as broken lines (e.g., from grid square 20-30 to 25-35) and named (e.g., "Unsurfaced road", "Secondary road").

On the outline map:

Part b(ii)

Trigonometrical beacons: Marked as ∙\bullet at positions (e.g., 1855, 2248) and named (e.g., "Trig 1", "Trig 2").

Part b(iii)

River Jorani and tributaries: Drawn as meandering blue lines with arrow showing flow direction.

Part c· 3 steps

Three reasons for the direction of flow of River Jorani:

  1. Gradient/relief - The river flows from high altitude areas (contours 1500m+) in the north-west to lower areas (800m) in the south-east as shown by V-shaped contours.

  2. Underlying rock structure - Fault lines and strike direction influence flow along lines of weakness.

  3. Regional slope - Overall south-easterly tilt of the area.

Part d· 3 steps

Three drainage characteristics:

  1. Dendritic drainage pattern - Tributaries join main river at acute angles resembling tree branches (grid sq.

    15-25).

  2. Perennial river - River Jorani shown by solid blue line with consistent width indicating permanent flow.

  3. Meandering course - River has loops and bends in flat valley bottom (grid sq.

    28-32).

Part e· 3 steps

Account for limited settlement:

  1. Steep slopes - High relief with close contours discourages settlement due to erosion risk (e.g., hill at 2000m, grid 10-20).

  2. Swampy areas - Marshes along river (hachured areas, grid 30-35) prone to flooding.

  3. Thick forest/vegetation - Forest reserve limits clearance for farming/housing.

Part f

Describe relief using evidence:
The area has varied relief. Steep slopes on hill (grid 12-18, contours from 1200m to 2100m, close spacing). Gentle slopes in valley (wide contour spacing 1000-1200m, grid 25-35). Flat plateau top (grid 05-10, 1600m contour).

Part g

Rainfall and temperature distribution table (typical for stations):

\begin{tabular}{|c|c|c|}
\hline
Station & Annual Rainfall (mm) & Mean Temp (∘^\circC) \
\hline
U & 1200 & 22 \
V & 1000 & 24 \
W & 900 & 25 \
X & 800 & 26 \
\hline
\end{tabular}

Explanation: Rainfall decreases eastwards due to rain shadow; temperature increases with decreasing altitude.
