What is rock called after it is ejected from a volcano and it cools?

Rock that is ejected from a volcano and cools is called volcanic rock or lava rock. This type of rock typically has a fine-grained texture due to rapid cooling.


What are things that are ejected from a volcano.?

The matter thrown out of a volcano while it is erupting is called lava, and it consists of melted rock matter. Before erupting, the lava moves underground towards the opening of the volcano. When it is underground like this, it is called magma.


These pieces of lava fragments are ejected from a volcano while they are still molten?

These sorts of ejecta are sometimes called 'bombs'.


What kind of rocks grapefruit sized thrown from a nearby volcano what are they called?

The rocks ejected from a volcano that are grapefruit-sized are typically called volcanic bombs. They are formed when molten lava is ejected into the air and solidifies before hitting the ground. Volcanic bombs can vary in size and shape depending on the type of eruption and the properties of the lava.


What type of volcano is build almost entirely from ejected lava fragments?

The type of volcano that is built entirely of ejected lava fragments is a volcanic cone. Volcanic cones can be of varying types, and it depends upon the nature, and size of the fragments ejected during the eruption.

What are large volcanic rock particles called?

Lapilli--Lapilli is pyroclastics the size of walnuts.Cinders-- Cinders are a type of pyroclastic material the size of a pea. According to the text, Earth An Introduction to Physical Geology, Cinders come in different forms when "ejected lava blobs are pulverized by the escaping gases".Blocks-- Blocks are particles larger than Lapilli's and are formed by harden lava.Bombs-- Bombs too help to produce blocks, but they are ejected as lava. They take on an streamline shape. They usually tend to fall on the slopes of a cone volcano and they can be ejected far from the volcano due to the force of escaping gasesI answered this earlier but this is a better answer ;)

What is a volcano shaft?

A volcano shaft refers to a vertical conduit or pipe-like structure that connects the magma chamber beneath a volcano to the surface. It allows magma, gases, and other volcanic materials to be ejected during an eruption. The shape and size of volcano shafts can vary depending on the volcano's specific characteristics.
