Cinder cone volcanoes are made of material called scoria, a low density form of basalt. Scoria forms as gases in the lava try to force their way out of the molten material through a vertical path. More » Science Earth Science Volcanoes

Steep-sided volcanoes, or stratovolcanoes, are primarily made from multiple layers of cinders and ash that were laid down during past eruptions. According to Oregon State University, stratovolcanoes are distinct from shi... More » Science Earth Science Volcanoes

Some of the advantages that volcanoes provide include the creation of new land, mineral deposits and beautiful landscapes that generate tourism. Active volcanoes actively cool the Earth, as their emissions remove heat fr... More »

Cinder cone, or scoria cone, volcanoes are cone-shaped hills that form when lava fragments are ejected from localized vents and pile up and solidify around the opening. Cinder cones can be standalone formations or develo... More » Science Earth Science Volcanoes

Paricutin is considered to be a scoria, or cinder, cone volcano. It stands at a height of 9,186 feet above sea level and has a lava field that covers an area of 10 square miles around it. As of 2014, it is the youngest W... More »

Cinder cone volcanoes form when high temperatures and pressure melt rock deep inside the Earth. Once a large amount of magma forms, it rises until it reaches the surface, creating an eruption. More »

Cinder cone volcanoes generally spew lava dramatically when they erupt, though the eruptions are not particularly dangerous to human populations. Dramatic and beautiful as the eruptions may be, they are quite insignifica... More »
