The third basalt-forming environment is a continental environment where a mantle plume or hotspot delivers enormous amounts of basaltic lava through the continental crust and up to Earth's surface. These eruptions can be from either vents or fissures.They have produced the largest basalt flows on the continents.t has a composition similar to gabbro. The difference between basalt and gabbro is that basalt is a fine-grained rock while gabbro is a coarse-grained rock. Basalt underlies more of Earth's surface than any other rock type. Most areas within Earth's ocean basins are underlain by basalt.

Play media. This short video shows the cloudy island of Cuba and the Bahamas as the ISS flies from the Caribbean Sea north-east to the Atlantic Ocean. In the video, you can see Cuba is mostly covered by clouds, but the reefs in the Bahamas stand out quite nicely.he land on the Bahamas has a foundation of fossil coral, but much of the rock is oolitic limestone; the stone is derived from the disintegration of coral reefs and seashells. The land is primarily either rocky or mangrove swamp. Low scrub covers much of the surface area.
