Ans. The distribution of oceans and continents has significant implications for human settlements and biodiversity. Coastal areas, where land and sea meet, are often densely populated due to their access to resources and transportation routes. The proximity to oceans also influences economic activities such as fishing, trade, and tourism. The distribution of continents determines the availability of land for agriculture and habitation. In terms of biodiversity, different regions of the world, with their unique oceanic and terrestrial ecosystems, support a wide variety of plant and animal species. The distribution of oceans and continents plays a crucial role in shaping the habitats and biodiversity hotspots on Earth.
