The cooling and hardening of magma deep underground results in what?
The cooling and hardening of magma deep underground results in igneous rock. Rare gems and diamonds can be found in igneous rock.
Type of rocked formed when lave or magma cools?
A rock that is formed when magma cools is called a igneous rock.
The process in which a rock changes as a result of heat generated from magma?
contact metamorphism
Which type of rock forms from magma?
magma is a mixture of several different types of rock.
Name the three major groups of rocks and describe how each forms?
The three groups are igneous, sedimentary, and metamorphic. igneous forms when magma or lava cools down. sedimentary forms when sediments (clay, sand, silt etc) gets compressed. and metamorphic forms when an igneous or sedimentary goes under very high temperatures and pressure
How is the texture of an igneous rock related to the rate which it cooled?
Quick cooling of magma results in small crystal formation. Slow cooling magma results in larger crystals.
What factors can effect the texture of a igneous rock?
Factors that can affect the texture of an igneous rock include the rate of cooling (fast cooling results in fine-grained texture and slow cooling results in coarse-grained texture), the mineral composition of the rock, and the amount of gas trapped within the magma during solidification. Other factors can include the amount of pressure present during crystallization and any subsequent deformation or alteration processes.
When magma crystallizes it becomes?
When magma crystallizes, it becomes igneous rock. Igneous rocks are formed by the cooling and solidification of molten rock material. The texture and composition of the igneous rock are determined by the rate of cooling and the mineral content of the magma.
What factors affect the texture of igneous rock?
The cooling rate of magma is the primary factor that affects the texture of igneous rocks. Rapid cooling results in fine-grained texture, while slow cooling leads to coarse-grained texture. The mineral composition of the magma also influences the texture, with high silica content producing light-colored and fine-grained rocks, and low silica content resulting in dark-colored and coarse-grained rocks.
The cooling and hardening of magma deep underground results in what?
The cooling and hardening of magma deep underground results in igneous rock. Rare gems and diamonds can be found in igneous rock.
What causes igneous rock to form?
Igneous rocks form when magma (molten rock) cools and solidifies either beneath the Earth's surface (intrusive) or on the surface (extrusive). The rate of cooling and the mineral composition of the magma influence the texture and characteristics of the resulting igneous rock.
How is the size of mineral crystals in igneous rock related to the rate at which they cool?
When igneous rocks cool quickly, they have small crystals and have a texture that may be described as aphanitic. When igneous rocks cool slowly, they have much larger crystals and have a texture that may be described as phaneritic or pegmatitic.
What are the factors that controls most texture in igneous rocks?
The rate of cooling is the main factor that controls texture in igneous rocks. Faster cooling leads to fine-grained textures, while slower cooling leads to coarse-grained textures. Other factors that can influence texture include the mineral composition of the magma and the presence of gases or water vapor during solidification.
Is the texture of an igneous rock determined by the composition of the magma?
No. The texture is determined by the amount of time the magma had to cool and solidify. Slow cooling magmas produce larger crystals and therefore have a coarse grained texture. Quick cooling magma or lava produce small crystals and a fine grained rock texture.
Crystallization from cooling magma describes one way that?
minerals form
What is the texture of an igneous rock when it was formed from cooling maga deep beneath the earth?
The texture of an igneous rock formed from cooling magma deep beneath the earth is typically coarse-grained. This is because the slower cooling process allows larger mineral crystals to form within the rock.
Extrusive igneous rock are made from?
Extrusive igneous rocks are formed from lava that cools and solidifies quickly on the Earth's surface. This rapid cooling results in small mineral crystals or a glassy texture in the rock. Examples of extrusive igneous rocks include basalt, andesite, and rhyolite.
