What are three types of igneous rock?
Three types of igneous rocks are basalt, granite, and obsidian. Basalt is a dark-colored fine-grained rock, granite is a light-colored coarse-grained rock, and obsidian is a natural glass formed from rapidly cooled lava.
Which igneous rock is an extrusive rock?
Basalt, Rhyolite, Obsidian and Andesite. There's many more but these are the main ones.
Which rock has large mineral grains-granite basalt obsidian pumice?
Granite has large mineral grains compared to basalt, obsidian, and pumice. It is an intrusive igneous rock formed from the slow crystallization of magma beneath the Earth's surface, allowing large crystals to develop. In contrast, basalt has smaller grains due to its rapid cooling, while obsidian is volcanic glass with no visible grains, and pumice is a light, porous rock with small, frothy bubbles.
Is basalt cooled slowly?
In reference to the cooling of magma into rock, basalt is formed from rapid cooling.
Name a volcanic rock?
Obsidian, basalt, andesite, pumice.
A black rock formed from cooled lava?
Obsidian
What is the difference between basalt and obsidian?
Basalt is a dark-colored volcanic rock formed from the rapid cooling of lava, while obsidian is a dark volcanic glass formed from the rapid cooling of lava with high silica content. Basalt has a crystalline structure, while obsidian is amorphous and often exhibits conchoidal fracturing. Basalt is typically denser and more resistant to weathering compared to obsidian.

What is an igneous rock that forms at the surface?
