Basalt is a volcanic rock that is formed from the solidification of lava. It is a common rock type that is found all over the world. Basalt is known for its durability, strength, and resistance to weathering. In this article, we will explore the definition and meaning of basalt, its origin, associations, synonyms, antonyms, and example sentences.
Definitions
Basalt is a type of volcanic rock that is formed from the solidification of lava. It is composed mainly of plagioclase and pyroxene minerals. Basalt is a dark-colored rock that has a fine-grained texture. It is commonly used as a building material, as it is very strong and durable.
