Step 1
3.1.1 Why did the farmer select site V to grow his/her crops?
Answer
The farmer likely chose site V for several favorable conditions. Firstly, the area is characterized by a flat land or gentle slope, which is advantageous for farming activities. Additionally, site V is located near a river or a water source, ensuring irrigation needs are met. It may also possess fertile soil, conducive for crop growth, and has infrastructure such as roads that facilitate access to markets.
Step 2
3.1.2 Crops are stored in local silos. Is this a primary, secondary or tertiary activity?
Answer
The storage of crops in local silos is classified as a tertiary activity. This is because it involves the sector of the economy that provides services, in this case, the storage and management of agricultural produce.
Step 3
3.1.3 The suitability of site V for cultivation may be reduced by flooding. Explain this statement.
Answer
Site V's cultivation potential can be hampered by flooding, especially since it is located near a river. During periods of heavy rainfall, the river may overflow its banks, inundating the surrounding areas. This flooding can wash away crops, erode soil, and alter the topography, making farming more difficult. Additionally, waterlogged soils can lead to poor root development and reduced crop yields.
Step 4
3.1.4 The farmer at V noticed that early morning mist in winter starts to clear from the bottom of the valley, as indicated in the sketches below. Explain why this happens.
Answer
At around 07:00, mist covers the valley as the temperatures are cooler. As the sun rises and the temperatures increase between 09:00 and 11:00, the mist dissipates due to the warming of the air. Terrestrial radiation warms the valley, causing the moisture in the air to evaporate. This process results in a clearer environment as the mist lifts. The valley's topography may contribute to cooler air settling at the bottom, leading to this phenomenon.
