Volcano and Geyser - heat drives the engine that makes rocks and minerals for the crystal collector

Some interesting volcano facts ...

 

Formation and composition 

• Volcanoes are created when magma, or molten rock, rises to the Earth's surface. Once the magma erupts, it becomes lava.

• Volcanic ash is not soft but made of tiny, sharp fragments of rock, minerals, and volcanic glass.

• Volcanic eruptions can create new land, forming islands like Surtsey and parts of Hawaii. 

 

Location and activity 

• About 75% of the world's active volcanoes are located around the Pacific Ocean's Ring of Fire.

• Most of the planet's volcanoes are underwater, forming submarine volcanoes.

• Volcanoes can be classified as active, dormant (sleeping), or extinct.

• The tallest volcano on Earth is Mauna Loa in Hawaii, which is over 33,500 feet tall from its base on the ocean floor.

• The largest volcano in the solar system is Olympus Mons on Mars, which is more than twice the height of Mount Everest. 

 

Effects and other facts 

 

• Large eruptions can cause a temporary global cooling effect by reflecting sunlight with ash and gases.

• In 1883 the eruption of Krakatoa killed over 36,000 people, mostly from a tsunami, and the 1902 eruption of Mount Pelée resulted in about 30,000 deaths from pyroclastic flows

• Some volcanic ash clouds can generate lightning due to static electricity from hot particles colliding.

• The eruption of the Krakatoa volcano in 1883 created the loudest sound ever recorded.
