What is a mountainous vent in the earth's crust that can spew out lava?
A volcano is a mountainous vent in the Earth's crust that can spew out lava, ash, and gases. Volcanoes are typically formed at tectonic plate boundaries or hot spots in the Earth's mantle, where magma rises to the surface. Eruptions from volcanoes can vary in intensity and can have significant impacts on the environment and surrounding communities.
What is an opening in the Earth's Surface through which lava can flow?
An opening in the Earth's surface through which lava can flow is called a volcano. When pressure builds up beneath the Earth's crust, it can force magma to erupt through a vent in the form of lava, gases, and ash.
Cone shaped mountains that spew out lava or gas?
These mountains are likely volcanoes, with the conical shape formed by layers of hardened lava and volcanic ash. The lava and gas are released during volcanic eruptions, which occur when pressure builds up beneath the Earth's surface and forces magma to the surface. Eruptions can vary in intensity and can have significant impacts on the surrounding environment.
Differences between lava and ash landforms and magma landforms?
Lava landforms are created by the eruption and cooling of molten lava on the Earth's surface, forming features like lava flows, lava domes, and lava tubes. Ash landforms are the result of volcanic eruptions that produce ash and volcanic debris, creating features like cinder cones, ash clouds, and pyroclastic flows. Magma landforms are underground structures formed by the cooling and solidification of magma, such as plutons, batholiths, and dikes.
What is the definition of layer of ash and lava?
A layer of ash and lava is a geologic feature formed by the deposition of volcanic ash and solidified lava during volcanic eruptions. These layers can build up over time to create thick sequences of volcanic material, which can be preserved in the rock record as distinct stratigraphic units.
What are the most devastating volcanoes?
ones that spew lava straight up and those that make a lot of ash
What type of lava flow does mount meakan have?
it has pyroclastic flow and has small eruptions of ash.
Does San Andreas Fault spew lava?
no
What are the long term effect caused by a volcano?
When volcanos erupt they spew ash and moltant lava all over the place. They can cause lots of problems with crop damage.
What spewed out of a volcano?
When a volcano erupts, it can spew out a mixture of hot gases, ash, lava, and rocks. This material, known as volcanic ejecta, can vary in composition depending on the type of volcano and the dynamics of the eruption. Eruptions can be highly explosive with significant ash clouds, or more effusive with slow-moving lava flows.
Why are volcano's bad?
Because they spew lava and ash everywhere, which means that it would destroy property and vegetation. Volcanoes also create a poisonous gas for humans called carbon monoxide.
What are the natural hazards on mt stromboli?
?pyroclastic flow, lava, ash, cinder, and bombs
What is a mountainous vent in the earth's crust that can spew out lava?

Eruptions from volcanoes can vary in intensity and can have significant impacts on the environment and surrounding communities.
Is block lava the same as pyroclastic flow?
No. Block lava is low-moving viscous lava, usually of andesitic or similar composition. A pyroclastic flow is a very fast-moving mixture of hot ash, rock and gas.
What lava flow does Mount Pinatubo have?
Mount Pinatubo is most famously known for its 1991 eruption, which resulted in a massive column of ash and volcanic materials being expelled into the atmosphere. This eruption did not involve a lava flow, but rather a pyroclastic flow, which is a mixture of hot ash, gas, and rock fragments that surged down the slopes of the volcano at high speeds.
Does mt Pinatubo's lava flow violently or quietly?
Mount Pinatubo erupt violently, but does not produce lava flows. It creates massive clouds of ash and pumice.
What is an opening in the Earth's Surface through which lava can flow?
An opening in the Earth's surface through which lava can flow is called a volcano. When pressure builds up beneath the Earth's crust, it can force magma to erupt through a vent in the form of lava, gases, and ash.
