When lava cools very suddenly (a process known as quenching), it creates a glassy, or hyaline, texture. This sudden cooling also creates very small, often microscopic, crystals in the rock. The most well-known example of a glassy textured igneous rock is obsidian.

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.


What 2 igneous are formed by fast cooling lava?

Two igneous rocks formed by fast cooling lava are basalt, which is a fine-grained volcanic rock, and obsidian, which is a natural glass formed from rapidly cooling lava without crystal growth.


How would a rock that formed from lava cooling on the Earth's surface compare with a rock that formed from magma cooling deep in the Earth's crust?

A rock formed from lava cooling on the Earth's surface would have smaller mineral grains due to rapid cooling, making it fine-grained (such as basalt). In contrast, a rock formed from magma cooling deep in the Earth's crust would have larger mineral grains due to slower cooling, resulting in a coarse-grained texture (such as granite).


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 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.

How is a rock from cooling lava classified?

A rock formed from cooling lava is classified as an igneous rock. Igneous rocks are formed from the cooling and solidification of magma/lava. They can be further classified based on their mineral composition, texture, and formation process.

Is igneous rock that formed from cooling lava fined-grained?

yes because of the fast cooling rate

What is the name of the crystal grain that is formed when molten rock cools slowly?

The texture of the rock product of slow cooling magma is referred to as coarse grained.


How would you best describe the texture of an igneous rock that formed extremely slowly underground?

The texture of an igneous rock that formed extremely slowly underground would likely be coarse-grained. This slow cooling process allows for the growth of large mineral crystals within the rock, leading to a visibly grainy texture.


The size of the mineral crystals found in an igneous rock is directly related to the?

the rate melted rock cools.


Which igneous rocks would be formed by the fastest cooling of lava?

Glassy textured extrusive igneous rock, such as obsidian.


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.
