The Earth is divided into two hemispheres by the Equator:
1. Northern Hemisphere: Located north of the Equator, it includes most of the landmasses such as North America, Europe, the majority of Asia, and parts of Africa. This hemisphere is home to the majority of Earth’s population and experiences seasonal changes opposite to the Southern Hemisphere.
2. Southern Hemisphere: Located south of the Equator, it includes South America, Australia, Antarctica, and the southern part of Africa and Asia. This hemisphere has fewer landmasses but extensive ocean coverage, which stabilizes temperatures. The Southern Hemisphere’s summer and winter seasons are opposite to those in the Northern Hemisphere.
These hemispheres influence climate and seasonal patterns globally, impacting agriculture, wildlife, and human activities based on their distinct climates.

The Andaman and Nicobar Islands are strategically significant in India’s geography, located in the Bay of Bengal, close to Southeast Asia. They form India’s eastern maritime boundary, strengthening national security in this region. Due to their geographic positioning, they serve as natural shields against cyclones and storms, helping to reduce their impact on the eastern coastline.
The islands also play an important role in the Indian monsoon system by regulating moisture and influencing the weather in mainland India. The rich biodiversity in these islands includes tropical rainforests, coral reefs, and various endangered species, making them essential for India’s ecological health and tourism. The Andaman and Nicobar Islands also support marine life, and their waters are essential for fishing and tourism industries. By helping to moderate climate and contributing to India’s economy, these islands are an invaluable part of India’s natural heritage and ecological balance.

The world’s oceans are interconnected, creating a continuous flow of water, nutrients, and marine life across different regions. This connectivity allows for a dynamic exchange of water masses, heat, and nutrients, which in turn sustains diverse marine ecosystems. Ocean currents, like the Gulf Stream and the Antarctic Circumpolar Current, distribute nutrients and warmth, supporting marine habitats in multiple regions and promoting biodiversity.
Marine life, including fish, whales, and migratory species, benefit from these connections as they move across oceans in search of food, breeding grounds, and suitable climates. This movement supports balanced food webs, as various species can find new habitats and interact within different ecosystems. For example, fish such as tuna travel thousands of miles, contributing to diverse fisheries. Thus, interconnected oceans ensure that marine life can thrive in various ecosystems, enriching biodiversity and maintaining the health of marine environments.

Tsunamis are large, powerful waves formed when underwater earthquakes, volcanic eruptions, or landslides displace huge volumes of ocean water. The energy released from these geological events travels through the water, generating waves that increase in height as they approach shallow coastal areas.Read more
Tsunamis are large, powerful waves formed when underwater earthquakes, volcanic eruptions, or landslides displace huge volumes of ocean water. The energy released from these geological events travels through the water, generating waves that increase in height as they approach shallow coastal areas. Upon reaching shore, these waves can cause devastating flooding, destruction, and loss of life.
One effective way to protect coastal areas is by implementing an early warning system. This system uses seismic data, satellite technology, and ocean buoys to detect unusual ocean movements. Once a potential tsunami is detected, alerts are issued to affected regions, allowing people to evacuate to safer, elevated areas. Such systems have been established in tsunami-prone regions, including the Indian Ocean, where India contributes to the Indian Ocean Tsunami Warning System. By providing timely warnings, these systems save lives and reduce property damage.

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.

(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.
