2024 Is chalk a rock - With its distinctive dark color, basalt is one of the most ubiquitous rocks on Earth and beyond. This fine-grained igneous rock predominates in the ocean basins, underlying the majority of the seafloor. Its vast abundance stems from effusive lava flows at divergent boundaries where tectonic plates are pulling apart.
