basalt lava. The volcanoes started erupting on the sea floor and over a very long time grew tall enough to rise above the surface of the ocean as islands. Lava that contains a greater amount of silica does not flow easily. Silicarich lava tends to build coneshaped volcanoes with steep sides. Vo lcanoes fed by silicarich magma tend to erupt explosively.

Rocks make up the majority of the Earth's crust. One of the most common rock is granite. The four minerals that make up granite are feldspar, quartz, mica, and hornblende. Granite was formed when magma cooled slowly forming crystals of the four minerals that make up the rock granite.
Basalt originates from volcanic magma and flood volcanoes, a very hot fluid or semifluid material under the earth's crust, solidified in the open air. Basalt is a common term used for a variety of volcanic rocks, which are gray, dark in colour, formed from the molten lava after solidification[1 4].
Basalt: Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Learn more about basalt .
Lava rock, also known as volcanic rock or basalt, forms after volcanic eruptions containing high levels of magnesium and iron. Magma reaches extreme heat and then cools, forming this highly porous rock. It has been estimated that volcanic rocks cover about 8% of the Earth's current land surface.
