Top 10 geology facts Selected as the most interesting among geology related questions in Geology quiz Which of the following European mountain ranges will rise the most in the next century?Scandinavian Mountains. The whole Scandinavia experiences uplift as a result of post-glacial rebound. In northern Europe, this is clearly shown by the GPS data obtained by the BIFROST GPS network. The average uplift is less than 1cm/year, but it may accumulate to 400m during next 10,000 years.Created by: globalquiz.orgtectonics facts » Which desert has this famous "eye"?Sahara. The Richat Structure in Mauritania, also known as the Eye of the Sahara, was interpreted as an asteroid impact structure, but no evidence for shock metamorphism has been found. Today scientists believe that it is a huge (40 km in diameter) and deeply eroded geologic dome.Created by: globalquiz.orgdeserts of Africa facts » What is the maximum depth of permafrost?1500 m. In areas of harsh winters the depth of the permafrost can be as much as 1,493 m (4,898 ft) in the northern Lena and Yana River basins. The overlying active layer that seasonally thaws is just 0.6–4 m (2.0–13 ft) thick.Created by: KasiaArctic facts » This kind of tilted forest is a common sight in subarctic taiga. What is this phenomenon caused by?The soil. The permafrost prevents trees from developing deep root system. Climate variations or forest fires can thaw the upper extents of the permafrost, creating a ground slump called thermokarst.Created by: Kasiataiga facts » Which lake is the oldest in the world?Lake Baikal is the deepest and the oldest lake, at least 25 million years old. It was formed as an ancient rift valley. Due its age, size and isolation, it hosts about 1000 endemic species of plants and animals (which can be found nowhere else in the world).Created by: globalquiz.orggeography of Russia facts » This is Sable Island, known as the graveyard of the Atlantic. It is about 109 miles southeast of Nova Scotia. What is the island origin?Post-glacial. Sable Island is believed to have formed from a terminal moraine deposited on the continental shelf near the end of the last Ice Age. It emerges from vast shoals and shallows which, in tandem with frequent fog and sudden storms, have caused over 350 recorded shipwrecksCreated by: globalquiz.orgsatellite photos facts » What is the typical source of pressure buildup inside a volcano?Degassing of magma. The whole process begins when hot magma is lifted by convection to the magma chamber. As the pressure in the chamber is lower than deep in Earth's crust, the gas starts to release. Since degassed magma has lower density, it may then sink and be replaced with new one. This process may build up huge pressure of gases, eventually causing explosion.Created by: Sumit Tamangnatural disasters facts » Which of European peninsulas has the most unstable shoreline?Scandinavian Peninsula. Before the 18th century, it was thought in Sweden that sea levels were falling. On the initiative of Anders Celsius a number of marks were made in rock on different locations along the Swedish coast. In 1765 it was possible to conclude that it was not a lowering of sea levels but an uneven rise of land, later recognized as post-glacial rebound.Created by: Debbie Foxgeography of Scandinavia facts » This photo has been taken at seaglass beach in Hawai'i. How is the seaglass formed?From garbage. Sea glass beaches are created from years of dumping garbage into an area of coastline. Sea glass begins as normal shards of broken glass that are then persistently tumbled and ground until the sharp edges are rounded.

Today, the cave is accessible because the mining company's pumping operations keep it clear of water. Unfortunately, the crystals deteriorate in air, and soon may be lost.Created by: globalquiz.orgcaves facts » Play geology quiz and see all the questions.
