The Big Questions (Page 27)

Question 1. What are oceans and continents? What are their names and their distribution?

Answer: Oceans are vast bodies of saltwater that cover about 71% of the Earth’s surface, while continents are large landmasses that make up the remaining 29%. The five oceans are the Pacific, Atlantic, Indian, Southern, and Arctic Oceans. The seven continents are Asia, Africa, North America, South America, Antarctica, Europe, and Australia. They are unevenly distributed, with most of the landmass located in the Northern Hemisphere.

Question 2. In what ways do oceans and continents impact life on Earth, including human life?

Answer: Oceans regulate the Earth’s climate, provide food, and are crucial for transportation and trade. They also support marine ecosystems. Continents host human societies, agriculture, and biodiversity. Their geographical features influence climate, natural resources, and human activities like settlement, culture, and economy.
