What type of rock igneous metamorphic or sedimentary makes up most of the continents?
The type of rock would be igneous.
When Magma is launched from a volcano forms what type of rock?
A volcano is made of extrusive igneous rock. The specific type of igneous rock will vary from one volcano to another.
What type of rock is formed when an igneous rock is cooled very rapidly?
When magma is cooled, it forms an igneous rock. When magma is cooled rapidly, that igneous rock is of the category called "extrusive" or "volcanic". When the magma is cooled very rapidly, the extrusive igneous rock formed will probably be holohyaline (glassy) in texture, or foamy like pumice.However if you take an igneous rock that is already rock and cool that very rapidly it will probably shatter owing to thermal stress. That might result in the formation of tuff.
Type of crystal grain that form when molten rock cools quickly?
Small crystal grains form when molten rock cools quickly. In an extrusive igneous rock, it's referred to as aphanitic texture.
What type of rock is sulfur?
Igneous
Peridotite is what type texture?
Peridotite is a dense, coarse-grained igneous rock.
An intrusive igneous rock will have what type of texture?
Intrusive igneous rock has a coarse, visible crystalline texture. Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. An igneous rock with a coarse texture is said to be phaneritic.
What type of rock are granite pumice and basalt?
Granite is an igneous rock with a coarse-grained texture, formed from the slow cooling of molten magma deep within the Earth's crust. Pumice is also an igneous rock, but with a frothy texture, formed from the rapid cooling of gas-rich lava. Basalt is another igneous rock, but with a fine-grained texture, formed from the cooling of lava on the Earth's surface, typically in volcanic environments.
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.
Is granite a igneous rock?
Yes, granite is a type of igneous rock.
A type of rock formed by molten rock solidified?
igneous rock
Which type of igneous rock has air bubbles in it?
Pumice is an igneous rock that contains air bubbles, giving it a porous texture. This lightweight rock forms from lava with high gas content that solidifies rapidly, trapping the bubbles inside.
What is the definition of Igneous Rock?
Igneous rock is a type of rock that forms from the cooling and solidification of magma or lava. It is classified based on its texture (coarse or fine-grained) and composition (silica content and mineralogy). Examples include granite, basalt, and obsidian.
What is felsite?
Felsite is a fine-grained volcanic rock composed mostly of feldspar and quartz. It is generally light in color and often has a smooth texture. Felsite is commonly used in construction and as a decorative stone.
Which type of rock is formed as a result of lava cooling quickly?
Igneous rock, specifically basalt, is formed when lava cools quickly. Basalt is characterized by its fine-grained texture due to rapid cooling at the Earth's surface.
What does not affect the type of igneous rock that forms?
The type of igneous rock that forms is primarily determined by the chemical composition of the magma from which it solidifies. Factors such as pressure and temperature can influence crystal size and texture, but they do not affect the type of igneous rock that ultimately forms.
What type of rock forms when heat and pressure change one type of rock into another?
Changes in the structure, texture, or mineralogy of existing rocks will create a metamorphic rock. Metamorphism can result from the effects of heat and/or pressure, or from the addition of ions from heated fluids. Examples of metamorphic rock are slate, schist, and gneiss.
