The top layer is pulled off to the sides and crumples, forming jagged regions of rock. As the flow moves off, the top of the aa hardens and insulates the layer beneath it. The aa lava flows are sharper and stiffer than the panhoehoe. There are two predominate "aa" and "panhoehoe" (both are words of Hawaiian origin). Mount Azul, on the island Isabela, recently erupted. Isabela, the newest island still has two active volcanoes craters. As this "hot spot" moves, more islands will grow. In the Nazca crust has a crack in it that allows magma to rise up, forming the volcanoes we see in the Galapagos. The volcanic activity of the Galapagos is due to the sublimation of the Nazca plate under the South American continental plate. This archipelago is millions of years old. ![]() Geography: The Galapagos archipelago is a perfect example of a chain island system. The uniqueness is also represented by the diversity of the range of organisms that coexist with one another. Due to the complexities of the climate surrounding the archipelago, the Galapagos' climate can be seen as a unique system. Scientists still have trouble accurately predicting the strength and timing of El Nino events. Fish die off and ageless coral become bleached by the higher ocean temperatures. Waterborne diseases such as malaria, cholera, and dengue erupted amongst the human populations. (Glantz) Diseases that affect the digestion systems break out in human populations. For example 45% of the population of cormorant died in the 1997 to 1998 El Nino event. Marine animals, such as the famous marine iguanas and flightless cormorants die off in huge numbers. Also the rainfall actually can increase over 2000 mm (Glantz) from the average rainfall. Meanwhile, air temperatures also jump by 2 degree Centigrade, or 4 degrees Fahrenheit. Water temperatures can jump up 2 to 4 degrees Centigrade, or 4 to 8 degrees Fahrenheit. Warm seas continue to bathe the island dumping water and tropical temperatures on the island. ![]() This occurs when the Humboldt Current shifts, so the dry season does not arrive. However, every few years, a weather anomaly known as El Nino occurs. The Humboldt (Peruvian) current typically moves up the western coast of South America, bringing cool, dry air to the Galapagos Islands (“Weather and the Galapagos Islands”). The reason why the Galapagos receives lower temperatures than expected from a tropical climate is because to the ocean currents that constantly bathe the island. However, mist usually forms further inland, allowing precipitation to reach the plants and fauna that lie away from the ocean. During the dry season, from April to December, the Galapagos receive less than 75 mm of rain on average (Slater). The Galapagos usually receives nearly 350 mm of rain during this time. From January to April it is the wet season. Like most tropical areas, the Galapagos has two seasons: the dry and wet seasons. The coolest the averages reach are 70 degrees in August. Then the temperature is around 87 degrees. On average, the warmest months are March and April. The temperatures average around the 80 degrees Fahrenheit. This is of 10/31/04.Ĭlimate: Although the Galapagos lies upon the equator, surprisingly, the temperature ranges are mild. So you know some of it repeats itself from summary 1. Alright this is my final research summary.
