Where do you find obsidian in minecraft?
Obsidian is usually found in caves underground where flowing water hits still lava.
How does water erode obsidian?
Water erodes obsidian primarily through a process called mechanical weathering, where the physical forces of moving water, along with sediment and other materials it carries, gradually wear down the glassy volcanic rock. Over time, the constant flow of water can create small fractures and chips in the obsidian's surface, leading to its breakdown. Additionally, chemical weathering can occur when water interacts with minerals in the obsidian, though this is less common due to its low reactivity. Overall, the combined effects of physical and chemical processes contribute to the erosion of obsidian by water.

Is obsidion a ignious rock?
Yes, obsidian is an igneous rock. It forms when molten lava cools rapidly and solidifies without crystal formation, resulting in a smooth, glassy texture. Obsidian is commonly found near volcanic areas.
Is obsidian metamorphic igneous or sedimentary?
Obsidian is an igneous rock.
Is obsidian rock found on the moon?
Yes, obsidian rock has been found on the Moon. During the Apollo missions, samples collected included volcanic glass, which is essentially obsidian formed from rapidly cooled lava. This indicates that volcanic activity occurred on the Moon in the past, producing materials similar to those found on Earth.
What does rock group does obsidian belong to?
Obsidian is in the Igneous rock group.
Is obsidian extrusive rock?
No. Obsidian is volcanic glass. Glass is amorphous and thus noncrystalline.
