Basaltic lava and the different types of lava flows Basalt is one of the most common types of rock in the Earth's crust, according to USGS, and makes up most of the ocean floor.

Volcanoes are grouped into four types: cinder cones, composite volcanoes, shield volcanoes and lava volcanoes.

Lava flows are outpourings of molten rock on the Earth's surface. They're very common in volcanic eruptions, and they come in different forms, according to AccuWeather. Pahoehoe lava is smooth and ...

The three common types of lava—basaltic, andesitic, and rhyolitic—contain different amounts of silica (SiO 2) and dissolved gases. They have different viscosities based on the amount of silica ...

Volcanoes produce many types of lava because of the varying elemental composition of the molten rock. So, when the lava cools it forms different rock types, such as basalt, pumice and obsidian.

The type of magma in the Earth can create different volcanoes. If the magma is quite thin, the gas can escape easily and there will not be an explosion.
