Final answer:
The conversion of logs into wooden furniture and iron ore into steel appliances are examples of secondary economic sector activities, which involve manufacturing raw materials into finished goods.
Step-by-step explanation:
The conversion of logs into wooden furniture or iron ore into steel appliances are examples of secondary economic sector activities. This sector, also known as the manufacturing sector, involves processing raw materials into finished goods.
For instance, the lumber industry processes logs into lumber, which is then used to create wooden furniture. Similarly, the steel industry transforms iron ore into steel, which can be used in appliances. The efficiency of transporting processed materials versus raw materials is significant, which adds economic value and can contribute to the development of secondary sector industries near primary sector resources.
