Abyssal rock is a term used to describe a type of rock that is formed at the bottom of the ocean. It is a unique and fascinating type of rock that has its own set of characteristics and properties. In this article, we will explore the definition and meaning of abyssal rock, its origin, and its associations.
Definitions
Abyssal rock is a type of igneous rock that is formed from molten magma that has cooled and solidified under the ocean’s surface. It is typically found at depths of 3,000 to 6,000 meters below sea level. Abyssal rocks are characterized by their fine-grained texture and dark color.
Origin
Abyssal rock is formed through the process of volcanic activity. When magma rises from the mantle and reaches the ocean floor, it cools and solidifies, forming abyssal rock. The process of forming abyssal rock can take millions of years, and it is influenced by a variety of factors, including temperature, pressure, and the chemical composition of the magma.
Meaning in different dictionaries

Associations
Abyssal rock is often associated with the ocean and the deep sea. It is also associated with the process of volcanic activity and the formation of igneous rocks. Abyssal rock has been studied extensively by geologists and oceanographers, who use it to understand the history and geology of the ocean floor.
Synonyms
