The Earth’s land and water distribution varies significantly between the Northern and Southern Hemispheres. The Northern Hemisphere contains the majority of Earth’s landmasses, including North America, Europe, most of Asia, and parts of Africa. This concentration of land leads to greater temperature variability, as land heats and cools more quickly than water. As a result, regions in the Northern Hemisphere often experience more extreme seasonal temperature changes.
In contrast, the Southern Hemisphere is dominated by vast oceanic expanses, including parts of the Pacific, Indian, and Southern Oceans. The water’s ability to retain heat provides a moderating effect, resulting in milder and more stable temperatures. This abundance of water also influences wind patterns and precipitation, as it provides more moisture, leading to frequent rainfall in certain areas. This distribution of land and water shapes climate patterns, biodiversity, and ecosystems in both hemispheres, impacting agriculture, population distribution, and weather systems globally.

(a) False. The Indian Ocean ranks as the third-largest of the world’s five major oceans, spanning about 20% of Earth's surface and bordered by Asia, Africa, and Australia. The Arctic Ocean, positioned near the North Pole, is actually the smallest ocean, covering only about 3% of Earth’s surface areaRead more
(a) False. The Indian Ocean ranks as the third-largest of the world’s five major oceans, spanning about 20% of Earth’s surface and bordered by Asia, Africa, and Australia. The Arctic Ocean, positioned near the North Pole, is actually the smallest ocean, covering only about 3% of Earth’s surface area. This distinction influences regional climates and marine ecosystems.
(b) True. Marine plants, particularly phytoplankton, contribute over 50% of Earth’s oxygen, essential for sustaining life. As phytoplankton photosynthesize, they release oxygen and absorb carbon dioxide, helping regulate atmospheric gases. This process is vital for maintaining Earth’s climate and supports marine ecosystems, illustrating the ocean’s key role in environmental balance and human well-being.
(c) False. Greenland, while the largest island, is not classified as a continent. It is geographically part of North America and is smaller than continents like Australia. Unlike continents, Greenland does not have diverse biomes or a vast range of ecosystems. Its classification as an island reflects both its size and its connection to the North American tectonic plate.
(d) False. The Southern Hemisphere is dominated by oceans, such as the Pacific, Indian, and Southern Oceans, resulting in a higher water-to-land ratio. The Northern Hemisphere has the majority of Earth’s landmasses, including Asia, Europe, and North America. This distribution creates climate differences, with the Southern Hemisphere experiencing milder, more ocean-influenced climates due to its water-dominated geography.
(e) False. Although underwater earthquakes are common causes, tsunamis can also result from volcanic eruptions and underwater landslides. These events displace significant amounts of water, producing powerful waves that can travel vast distances. The destructive impact on coastal areas highlights the need for early warning systems, which can detect various tsunami-causing events and help protect populations.
