The Galapagos Islands is a cluster of islands in the Pacific Ocean that sits right on top of the equator. The climate of the islands varies according to the elevations, but the temperature rarely rises over 27 degrees Celsius. At sea level, there is seldom rain and therefore only plants that can go extended time without water can survive, such as cacti. However, in the higher regions of the islands, there are large clouds of moisture, which help vegetation grow.
These are the islands that Charles Darwin visited while on his five-year voyage on The HMS Beagle, from 1831 to 1836. While visiting the islands, Darwin found that there were many unique species that had adapted to the Islands according to their environment.
