Pillow lava is a type of lava that forms underwater when hot magma is erupted into the ocean. This unique type of lava gets its name from its characteristic pillow-like shapes that form as the outer layer of the lava cools rapidly upon contact with the cold ocean water.
Formation of Pillow Lava
When magma is erupted underwater, the intense heat causes the outer layer to cool and solidify almost immediately, creating a glassy crust. As more magma is forced out from the center, the crust wrinkles and bulges, forming the distinctive pillow shapes that give pillow lava its name. This process is repeated as more lava is erupted, creating a series of interconnected pillow structures.
Composition and Characteristics
Pillow lava is typically made up of basaltic rock, which is low in silica and high in iron and magnesium. This composition gives pillow lava its dark color and allows it to flow more easily than other types of lava. The pillow structures can range in size from a few centimeters to several meters in diameter, depending on the rate of eruption and the depth of the water.
One of the key characteristics of pillow lava is its glassy crust, which forms as the outer layer cools rapidly in contact with the water. This crust can often be cracked or shattered, revealing the hot, flowing lava inside. Over time, as the pillows continue to erupt and cool, they stack on top of each other, creating a layered mound of pillow lava.
Significance and Study
Pillow lava formations provide valuable information to geologists and scientists about past volcanic activity and the history of the Earth's oceanic crust. By studying the size, shape, and distribution of pillow lava structures, researchers can better understand the processes of underwater volcanic eruptions and the evolution of oceanic ridges.
Volcanic activity underwater plays a crucial role in shaping the Earth's geology, and pillow lava offers a unique window into this dynamic process. As scientists continue to study these formations, they uncover new insights into the Earth's past and gain a greater understanding of the forces that have shaped our planet over millions of years.
