What is a rock that looks like smooth glass?
A rock that looks like smooth glass is often obsidian, a volcanic glass formed when lava cools rapidly. It has a shiny, glassy appearance and can be black, brown, or even green. Other rocks that may resemble glass include some types of jasper or agate, but obsidian is the most commonly associated with a glass-like texture. Its smooth surface can be sharp and is often used for tools and decorative items.
What texture of obsidian?
Obsidian is an extrusive rock that cooled very rapidly without forming crystals. As a result, obsidian has a smooth, shiny texture of a thick piece of glass.
What is the difference between an igneous rock with glassy texture and a fine texture what cause it?
The primary difference between an igneous rock with a glassy texture and one with a fine texture lies in their cooling rates and crystal formation. A glassy texture, seen in rocks like obsidian, forms when lava cools very rapidly, preventing crystal growth and resulting in a smooth, glass-like appearance. In contrast, a fine texture, found in rocks like basalt, occurs when lava cools more slowly, allowing small crystals to form, which are often too tiny to see with the naked eye. The cooling environment, whether rapid or gradual, is what ultimately dictates the texture of the rock.
How a rocks surface looks and feels is the rocks what?
Texture is the word used to describe a rock's constituent mineral size and arrangement, visible on a freshly fractured surface. Because a rock's surface can be weathered to a smooth or polished surface, the way it feels is not usually included in a description of texture.
What is an example of how texture can provide clues as to how and where a rock is formed?
To determine the texture of rock when rock is forming , you must test the mohs hardness scale and wait for the feedback. Then analyze the information into categories of largest to smallest. Once you do that you must share your answer if it is either igneous, metamorphic, or sedimentary.
What igneous rock has a smooth glass like texture?
Obsidian is an igneous rock that has a smooth glass-like texture. It is formed when lava cools rapidly without crystal formation, resulting in a glassy texture.
What is the texture for sulfur?
The texture of sulfur is like a rock.
What is the resulting texture of igneous rock that is formed from extremely rapid cooling lava in which no crystals form?
The resulting texture is called glassy. This texture forms when lava cools so quickly that no crystals have time to grow, resulting in a smooth, glass-like appearance.
What does term ''glassy'' mean when talking about igneous rock texture?
Glassy texture in igneous rocks refers to a smooth and reflective appearance resembling glass. This texture is formed when the molten rock cools rapidly, preventing mineral crystals from developing. Glassy texture is typically seen in obsidian, a type of volcanic glass.
What is the relationship between igneous rock's texture and where it is formed?
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.

What do you call the way a rock feels?
The way a rock feels is referred to as its texture. Texture can vary from smooth to rough, depending on factors like the composition and history of the rock.
