Answer:
Extrusive igneous rock is formed by the crystallization of magma release after volcanic eruption at the Earth surface. They are characterized by fine grained textures because of rapid cooling they do not form large crystals. Extrusive rocks with fine grained textures are called aphanitic rocks. The most common extrusive igneous rock is basalt. Other examples include rhyolite, andesite and obsidian. Extrusive igneous rocks erupt quickly and they form small crystals. Some of these rocks cools slowly that they form glass. These rocks includes andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria and tuff.
The common characteristic of extrusive igneous rock is the b. forms crystals
Rapid cooling of magma produces small crystal rocks.

Abiotic factors play a large role in determining the types and traits of organisms that inhabit a given ecosystem. For example, air temperature, soil pH and type, the availability of fresh water, and the amount of sunlight all interact to influence what types of vegetation can thrive in a terrestrial habitat.
