Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
What else can I help you with?
Magma that is ejected during a volcanic eruption forms igneous rocks?
Yes, when magma is ejected onto the Earth's surface during a volcanic eruption, it cools and solidifies to form igneous rocks. These rocks can vary in composition and texture depending on the type of magma and how fast it cools.
Is Tephra igneous?
Yes, tephra is igneous in origin. Tephra is made up of fragmented rock material ejected during a volcanic eruption, such as ash, pumice, and volcanic bombs, and is typically formed from solidified magma or lava.
What type of igneous material cools the fastest?
Igneous material that cools the fastest is typically volcanic glass, such as obsidian. This occurs when lava is rapidly expelled during a volcanic eruption and cools quickly upon contact with air or water, preventing the formation of crystal structures. As a result, volcanic glass lacks a crystalline structure and has a smooth, glassy appearance.
What rock group does pumice belong to?
Pumice forms from the eruption of volcanoes. It occurs from hot pressurized rock that gets ejected from the volcano during eruption.
Why is the atmosphere affected after a volcanic eruption?
likely due to the gases and ash that are ejected during the eruption
What is volcanic throat?
it is the upperpart of the volcanic chimney during an eruption it is the upperpart of the volcanic chimney during an eruption

What are pyroclastics?
Pyroclasts are rock fragments or rocks formed from volcanic fragments thrown into the air as a result of a volcanic eruption. Also known as tephra, some examples of these rocks include pumice, reticulite and scoria.

What is the name of the cloud that volcanos make when they erupt?
The cloud of ash, gas, and rock fragments that is produced during a volcanic eruption is called a volcanic plume or eruption cloud.
What part of the earths interior is spewed out during a volcanic eruption?
Which part of the Earth's interior is spewed out in a volcanic eruption?
How many people died in the Lassen Peak volcanic eruption 1915?
Three people died in the Lassen Peak volcanic eruption in 1915. They were suffocated by toxic gases and ash during the eruption.
What is the light sort rock produed during volcanic eruption?
Pumice.
How much people died during the Iceland volcanic eruption?
about 600
