One of the most active volcanoes today is in Mauna Loa, Hawaii. Is it magma or lava? Well, it’s both! Magma is the liquid rock inside the volcano, and once it spills out of it, it is called lava. Lava will burn everything in its path. How Does a Volcano Erupt Well, it’s ...
Generally speaking, the volcanoes that cause the most trouble for humankind are of the kind known as stratovolcanoes or composite volcanoes. Like other types of volcanoes, stratovolcanoes form around vents from which molten rock, or magma, reaches the Earth's surface as lava. They're most commo...
Volcanoes vary a great deal in their destructive power. Some volcanoes explode violently, destroying everything in a mile radius within minutes, while other volcanoes seep out lava so slowly that you can safely walk all around them. The severity of the eruption depends mostly on the composition ...
There are over 1500 volcanoes all around the world. While some are dormant, there are many that are active and are in a constant state of eruption. Magma reaches the surface and erupts into hot liquid lava through the lava tubes that run from the Earth’s magma to the surface. Causes of...
How are cinder cones (volcanoes) formed from a build-up of gases? Explain the term vapor diffusion. Describe the chemistry behind how an instant cold pack works. Explain how a voltaic cell works. Be sure to mention the various parts of the voltaic cell and what they have to do with how...
It’s a tropical destination with rainforests, countless beaches, volcanoes, and mountains. The ‘pura vida’ lifestyle, means pure life—and is the true philosophy of Costa Rica. With Worldpackers volunteer opportunities in Costa Rica, you can work on projects to protect sea turtles and ...

Glaciers, volcanoes, forested coasts—these distinctive Alaskan landscapes are packed into this rarely visited reserve. Here’s what you need to know.
First of all, volcanoes are the reason Iceland exists.The area where volcanic activity has created the island over 18 million years rests on a constructive plate boundary called the Mid-Atlantic Ridge, which is part of one of the world's longest mountain ranges (albeit underwater) at nearly...
Andes:Formed by the subduction of the Nazca plate beneath the South American plate, the Andes are a volcanic range with active volcanoes along the subduction zone. Appalachians:An older range in North America, formed about 480 million years ago, the Appalachian mountains display a folded structure...
