Difference between Extrusive rock and Pumice

Extrusive rock vs. Pumice

Extrusive rock refers to the mode of igneous volcanic rock formation in which hot magma from inside the Earth flows out (extrudes) onto the surface as lava or explodes violently into the atmosphere to fall back as pyroclastics or tuff. Pumice, called pumicite in its powdered or dust form, is a volcanic rock that consists of extremely vesicular rough-textured volcanic glass, which may or may not contain crystals.

Andesite

Andesite is a volcanic rock of intermediate composition.

Basalt

Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon.

Caldera

A caldera is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption.

Crystal

A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

Dacite

Dacite is a volcanic rock formed by rapid solidification of lava that is high in silica and low in alkali metal oxides.

Igneous rock

Igneous rock, or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic.

Lava

Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface.

Magma

Magma is the molten or semi-molten natural material from which all igneous rocks are formed.

Matrix (geology)

The matrix or groundmass of a rock is the finer-grained mass of material in which larger grains, crystals, or clasts are embedded.

Pyroclastic rock

Pyroclastic rocks are clastic rocks composed of rock fragments produced and ejected by explosive volcanic eruptions.

Scoria

Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock formed by ejection from a volcano as a molten blob and cooled in the air to form discrete grains called clasts.

Vesicular texture

Vesicular texture is a volcanic rock texture characterized by a rock being pitted with many cavities (known as vesicles) at its surface and inside.

Volcanic rock

Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano.
