Igneous rocks are formed after solidification of lava (Magma inside earth). They are rich in metals as metals are found deep in earth and hence they come out in molten state with the lava.
The froth that runs out of a volcano is called lava. It is molten rock that flows from the vent of a volcano during an eruption. When lava cools and solidifies, it forms different types of volcanic rocks.
This is the description of a volcanic eruption.A eruption.
The solid flying debris of a volcano is known as tephra, which includes various fragments such as ash, pumice, and volcanic rocks ejected during an eruption. This material can vary in size from fine ash particles to larger volcanic bombs and blocks. Tephra can travel considerable distances from the eruption site, posing hazards to air travel, infrastructure, and nearby populations. Its composition and size can provide insights into the eruptive history and behavior of the volcano.
Flying solid debris from a volcano is typically referred to as volcanic ash. This ash is composed of pulverized rock, mineral, and glass fragments that are ejected into the air during an explosive volcanic eruption. Ash can travel long distances and pose risks to aircraft, infrastructure, and health.
The main solid parts of a volcano include the crust of the Earth, the volcanic rock that forms the cone and vent of the volcano, and the hardened lava flows. Beneath the surface, there are also solid magma chambers where molten rock accumulates before erupting.
"Ejected debris" the the solid material shot into the air by an erupting volcano (as opposed to the gasses ejected by the same eruption).
Cinders are small, solid pieces of lava that are expelled during a volcanic eruption. When cinders fall in vast quantities, they can form a layer of loose volcanic debris called a cinder cone. This type of volcano has a steep slope due to the accumulation of cinder material.
The two terms that describe the substance produced by a volcano are "lava" and "tephra." Lava refers to molten rock that flows from a volcanic eruption, while tephra encompasses solid fragments such as ash, pumice, and volcanic rocks ejected into the air during an eruption. Both substances can significantly impact the surrounding environment and contribute to the formation of new geological features.
Bedrock in a volcano refers to the solid, unweathered rock that lies beneath the volcanic materials such as ash, lava, and pyroclastic flow deposits. It forms the foundation on which the volcano is built and can help determine the stability and structure of the volcano.
Whether a volcano should erupt or not depends on the pressure building up in the mantle underneath. In some areas, the solid cap formed over a dormant volcano is sufficient to prevent a new eruption. In this case, the pressure could move away to find a weaker area and a new eruption and the birth of a new volcano could appear.
Tephra is produced naturally by volcanic eruptions and refers to the material produced when the volcano erupts. Tephra comes in a range of forms and are classified by size Ash, Lapilli or Volcanic blocks.
