Final answer:
Geographic features such as river valleys and mountain ranges play a crucial role in shaping economic activities. The fertile Nile River Valley supports agriculture, while the Alps promote tourism and winter sports industries.
Step-by-step explanation:
Geographic features have a significant impact on the development of economic activities. For instance, areas with fertile land and favorable climates, like river valleys, are ideal for agricultural activities. The Nile River Valley in Egypt has been the agricultural hub for millennia due to the annual flooding that enriches the soil, making it suitable for growing crops such as wheat and cotton. This has led to a thriving agricultural economy in the region.
Similarly, mountain ranges like the Alps in Europe have shaped economic activities in their vicinity. They are not only natural barriers for trade and travel but also offer opportunities for tourism and winter sports industries. Ski resorts and related businesses thrive in these regions because of their geographic features.
In summary, physical geographic features like rivers and mountain ranges are instrumental in determining where and what type of economic activities can flourish, due to factors including climate, soil fertility, and natural barriers or attractions for tourism.
