Lava is made up of volcanic glass, volcanic gases, and crystals. Once the magma arrives near the surface and starts to cool, it crystallizes the minerals and forms volcanic gases.
What else can I help you with?
What is the lava composition of the abu volcano?
there is a type and its lave
Whats the composition of lava for Mt Pelee?
The lava composition of Mount Pelée in Martinique is typically andesitic, which means it contains minerals such as plagioclase, pyroxene, and amphibole. Andesitic lava is intermediate in composition between basaltic (low silica content) and rhyolitic (high silica content) lavas.
What type of lava is considered intermediate composition?
Andesitic lava is considered intermediate in composition. It has moderate silica content and viscosity, resulting in eruptions that produce both effusive and explosive activity.
What is the lava in the Andes called?
The lava in the Andes is typically referred to as Andesitic lava, due to its composition being rich in silica and forming characteristic volcanic landforms in the Andean region.
Does mt st Helens have pahoehoe or AA lava?
Niether. Pahoehoe and a'a are both varieties of basaltic lava. The material from Pinatobo is of a dacitic composition, which is much more viscous than a'a or pahoehoe. It tends to erupt explosively, producing ash and pumice rather than lava flows. When dacitic lava does flow it creates a block lava flow.
What is the lava composition for surtsey?
The magma and lava of Surtsey has a composition of alkali Olivine Basalt.
What is the composition of a lava dome?
Lava domes are generally composed of felsic, highly viscous lava, usually dacite or rhyolite.

What rock forms from lava that cools?
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
What rock form from cooling lava?
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
What type of scientists study lava?
Volcanologists study lava. They examine the behavior, composition, and effects of volcanic activity, including the study of lava flows and eruptions.
What type of lava is considered intermediate composition?
Andesitic lava is considered intermediate in composition. It has moderate silica content and viscosity, resulting in eruptions that produce both effusive and explosive activity.
What the composition of lava?
Lava is primarily composed of molten rock and consists mainly of silicate minerals, with significant amounts of silicon, oxygen, aluminum, iron, calcium, sodium, potassium, and magnesium. The exact composition can vary depending on the type of lava, with basaltic lava being rich in iron and magnesium, while rhyolitic lava contains higher silica content. Additionally, lava may contain dissolved gases such as water vapor, carbon dioxide, and sulfur dioxide, which can influence its behavior during eruptions. The composition affects the viscosity, temperature, and eruptive style of the lava.
What different aspects of lava would a geologist examine?
A geologist would examine the composition of lava, including its mineral content and chemical composition. They would also investigate the temperature and viscosity of the lava, as well as its eruption style and flow behavior. Additionally, they might study the texture and structure of lava rocks to understand how the lava cooled and solidified.
What 3 factors affect the formation of lava?
Composition, heat, and pressure.
What is the lava in the Andes called?
The lava in the Andes is typically referred to as Andesitic lava, due to its composition being rich in silica and forming characteristic volcanic landforms in the Andean region.
