Step 1
Why did the farmer select site V to grow his/her crops?
Answer
The farmer selected site V primarily due to its favorable agricultural conditions. The site features flat land with a gentle slope, which is ideal for cultivation. It is located near a river and a water source, providing adequate irrigation for crops. Additionally, the soil in this area is fertile, which enhances the potential for high yields. Finally, access to infrastructure such as roads aids in transporting produce to markets.
Step 2
Crops are stored in local silos. Is this a primary, secondary or tertiary activity?
Answer
This activity is classified as tertiary. Tertiary activities involve services that support the primary and secondary sectors, and storing crops in silos is a service that helps preserve agricultural products for later sale and distribution.
Step 3
The suitability of site V for cultivation may be reduced by flooding. Explain this statement.
Answer
Site V is located in a low-lying area along the river's floodplain, making it vulnerable to flooding, especially during heavy rainfall. When flooding occurs, the crops planted in this area can be washed away, leading to significant losses. Additionally, the excess water may erode the soil, depleting its nutrients and making it less suitable for future cultivation.
Step 4
The farmer at V noticed that early morning mist in winter starts to clear from the bottom of the valley. Explain why this happens.
Answer
At 07:00, the mist covers the entire valley because the lower elevation remains cooler compared to higher ground. As the sun rises, the temperature begins to warm the valley's slopes, leading to the evaporation of mist. By 09:00, the heat from the sun causes the air near the slopes to warm significantly, and by 11:00, most of the mist evaporates as the valley approaches a near-complete warming, leaving the area almost clear.
