10 most difficult volcanos riddlesVolcanos quiz
Nearest which capital is this volcano located?
Popocatépetl is 70 km (43 mi) southeast of Mexico City, from where it can be seen regularly, depending on atmospheric conditions. Until recently, the volcano was one of three tall peaks in Mexico to contain glaciers. It is linked to the Iztaccihuatl volcano to the north by the high saddle known as the Paso de Cortés.
Visiting Antarctica, we will not be able to see:
the saltiest lake in the world
the most oxygenated lake in the world
a stony desert
In Antarctica we can find the Erebus high volcano at nearly 4 km, the Don Juan pond with a salinity of 44.2%, and the desert of the McMurdo Valleys. Lake Vostok with an oxygen content 5 times more than the average, however, is hidden under a 4 km layer of glacier.

What is the world's only active volcano that erupts natrocarbonatite lava?
Ol Doinyo Lengai
Ol Doinyo Lengai is an active volcano located in Tanzania. It uniquely produces natrocarbonatite lava. Due to this unusual composition, the lava is erupted at relatively low temperatures (approx. 500-600 °C). This temperature is so low that the molten lava appears black in sunlight, rather than having the red glow common to most lavas.
How often does the Stromboli volcano erupt?
every few minutes
every few weeks
every few years
every few decades
Strombolian eruptions are distinct bursts of fluid lava from the mouth of a magma-filled summit conduit. The explosions usually occur every few minutes at regular or irregular intervals. The explosions of lava, which can reach heights of hundreds of meters, are caused by the bursting of large bubbles of gas, which travel upward in the magma-filled conduit until they reach the open air.
