What is inside a rock?
somttimes crystals, sometimes (mostly) more rock
Why do plutonic rock and volcanic rock have big and small crystals respectively?
The size of the crystals is a function of the rate of cooling of the molten rock. The faster the molten rock cools, the smaller the crystals will be.
What type of sedimentary rock forms when crystals grow out of solution?
These minerals are called evaporites.
What causes volcanic rock to have no crystals?
rapid cooling, so that crystals do not form.
Must all rocks form crystals?
All rock does not contain mineral crystals. Obsidian, or volcanic glass, in particular is a rock that has cooled so quickly from lava that mineral crystals were not able to form.
What are hollow spheres in a limestone rock called?
Hollow spheres in limestone rock are called vugs. Vugs are formed when a cavity in the rock is later filled with minerals or crystals. They can vary in size and shape and are often sought after by collectors for their unique beauty.
Is it true that a hollow rock lined with crystals is a geode?
it is true.
What is a hollow rock lined with crystals?
a geode
What is a rock lined with mineral crystals?
A rock lined with mineral crystals is called a geode. Geodes are hollow rocks that contain a variety of different crystals inside, such as quartz, amethyst, or calcite. These crystals form inside the geode over time as mineral-rich water flows through and deposits minerals along the walls.
What are stones with crystals inside called?
Stones with crystals inside are called geodes. Geodes are natural rock formations that contain hollow cavities lined with crystals, often quartz or amethyst. They are often cut or broken open to reveal the beautiful crystals inside.
What is a hollow space in a rock?
A hollow space in a rock is called a vug or a vuggy. It is typically formed when minerals dissolve or are weathered away, leaving a cavity within the rock. Sometimes, vugs can be lined with crystals or other minerals.
What is a hollow rock that is often lined with mineral crystals?
That's a geode.
What is a crystal-lined rock called?
A crystal-lined rock is called a geode. Geodes are hollow rocks that contain sparkling crystals inside, formed by minerals depositing in the cavities of the rock over time.
What is a geod?
A hollow rock with crystals in it. See the related link for more information.
