Answer (1)
What is the Ring of Fire? The Ring of Fire is a major area in the Pacific Ocean basin where a large number of earthquakes and volcanic eruptions occur. It is shaped like a horseshoe and is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and tectonic plate movements. The Ring of Fire is home to about 75% of the world's active and dormant volcanoes.
What is an island? Give two examples. An island is a landmass that is completely surrounded by water. It can be found in oceans, seas, lakes, or rivers. Examples of islands include Hawaii (located in the Pacific Ocean) and Madagascar (located in the Indian Ocean).
Why are oceans important to life on Earth? Oceans are vital to life on Earth for several reasons:
They help regulate the Earth's climate by storing and distributing heat around the planet.
Oceans are a major source of food, providing fish and other seafood.
They produce oxygen through phytoplankton photosynthesis, which contributes significantly to the oxygen we breathe.
Oceans are a habitat for a diverse array of marine life.
Why is the Indian Ocean named after India? The Indian Ocean is named after India due to its strategic location at the head of the ocean and its extensive, ancient trade and cultural exchanges across and within the ocean. Historically, India was a significant presence in international maritime trade, which led to the ocean's name.
