Geology

Geology is a branch of natural science concerned with the Earth and other astronomical bodies, the rocks of which they are composed, and the processes by which they change over time. The name comes . Modern geology significantly overlaps all other Earth sciences, including hydrology. It is integrated with Earth system science and planetary science.

A geopark is a protected area with internationally significant geology within which sustainable development is sought and which includes tourism, conservation, education and research concerning not just geology but other relevant sciences. It also supports the communities that live in its boundaries.

Tossol is a Catalan word (hillock) used to refer to protuberances that form in lava flows and that when the lava cools become small hills. In the Jordà beech forest (in the Garrotxa Volcanic Zone Natural Park, in Catalonia, Spain) there are more than 50 tossols (spatter cones) formed by the interaction between lava flows and pre-existing wetlands that, when covered by lava at more than 1000 °C, boiled with large bubbles that raised and deformed the flow forming the tossols. These in the Garrotxa Volcanic Zone are fo

Landscape originates from the erosion of joints in the bedrock, leaving out small plateaus or ridges in between. Common in Fennoscandia.
