Water and lava: A fiery debate or a harmonious union?
Is water the gentle life-giver or a destructive force akin to lava? It's a question that sparks curiosity and controversy in the world of geophysics. While lava is known for its scorching heat and destructive nature, water is often seen as its opposite, nurturing life. But are these two elements truly as different as they seem?
Some experts argue that the answer lies in the nature of ice. If ice can be classified as a rock, then water, when heated, could potentially be lava. Minerals, like ice, have a highly ordered crystal lattice structure and are naturally occurring solids. Rocks, formed by chemically bound minerals, undergo a transformation when pushed deep into the Earth's mantle. They melt, creating magma, which eventually rises and erupts as lava.
But here's where it gets controversial: Peter Liberty, a geology enthusiast, suggests that ice is a mineral made from water, and when it melts, it becomes molten rock. This implies that water could be classified as lava. However, Paul Ashwell, a volcanologist, disagrees. He points out that lava has a more complex chemical composition than water, making it an unfair comparison. The water on Earth varies in salinity, but these differences are minimal compared to the diverse chemical compositions of magma.
And this is the part most people miss: the role of trace elements. Magma comes in various forms, each with unique major and trace elements. These elements significantly impact the type of rock formed. For instance, silica content in lava determines the formation of komatiite or rhyolitic rocks with distinct textures and colors. But water, when forming ice, doesn't incorporate trace elements into its structure, always resulting in ice, regardless of its initial state.
Enter Jade Umbsaar, who challenges this notion. Umbsaar highlights that, although rare, ice can include trace elements, behaving like a mineral. This similarity between ice and magma can't be overlooked. Umbsaar directs our attention to cryovolcanoes on Pluto, which erupt water that quickly freezes. If water is considered lava on other planets, why not on Earth?
The definition of a volcano becomes hazy when we explore other celestial bodies. Volcanism on Earth is well-understood, but cryovolcanism remains a mystery. Ashwell suggests that while cryovolcanoes share similarities with Earth's volcanoes, we can't confirm their exact mechanisms. So, are water and lava truly distinct, or are they more alike than we imagine?
Despite their differences in appearance and composition, water and lava might not be as disparate as we believe. Engaging in debates like this encourages us to question scientific dogma and explore new possibilities. The 'Is water lava?' debate may seem unusual, but it's these intriguing questions that propel scientific discovery forward, even if the answers remain elusive for now.
