Geology of the Canary Islands
The Canary Islands are a group of islands in the Atlantic Ocean that were formed by a process called volcanic activity. This means that hot molten rock, called magma, from deep underground rises up to the surface and creates new land.
The islands were formed over millions of years as volcanic eruptions continued to add more and more layers of rock to the surface. Some of the volcanoes are still active today, but most have been dormant for a long time.
The islands are made up of many different types of rock, including basalt, which is black and solid like granite, and tuff, which is lighter and more crumbly. The different types of rock were formed by different types of volcanic activity.
Over time, the islands have also been shaped by other natural forces like erosion and tectonic movement. Erosion is when water and wind wear away at the rock, smoothing it out and creating the islands’ famous rugged landscapes. Tectonic movement is when the plates that make up the Earth’s crust shift and move, causing earthquakes and changing the shape of the land.
Thanks to their unique geology, the Canary Islands are home to many fascinating geological features, including towering peaks, deep valleys, and even beaches made entirely of black volcanic sand. Scientists and geologists continue to study the islands to learn more about how they were formed and how they continue to change over time.
