Islands: Exploring unique ecosystems

Islands are fascinating geographical features that can be found all over the world. They are pieces of land that are surrounded by water, and they come in all shapes and sizes.

Formation of Islands

Islands can be formed through various geological processes. Some are the result of volcanic activity, where molten rock from beneath the Earth's surface erupts and forms new land. Other islands are created through the accumulation of sediment, such as sand or coral, over time.

Types of Islands

There are several types of islands, including continental islands, oceanic islands, and coral atolls. Continental islands are connected to a mainland, while oceanic islands are formed from volcanic activity in the middle of the ocean. Coral atolls are ring-shaped islands formed from the accumulation of coral reef around a central lagoon.

Unique Ecosystems

Islands are home to a wide variety of unique plant and animal species. Due to their isolation, many islands have evolved their own distinct ecosystems, with species that are found nowhere else in the world. This makes islands important areas for conservation and biodiversity.
