Generally speaking, yes. Magma that cools quickly will produce small, "fine grained" crystals.
Magma which cools slowly will generally produce rocks with larger, visible to the naked eye, crystals.
This is because while magma is cooling, crystals are forming. Generally, crystal which have more time to grow will be larger. Therefore, generally, the slower magma cools, the bigger the crystals will be. The faster lava cools, the less time crystals have to grow and are thus smaller, "fine grained".

What are formed when magma cools inside earth?
When magma cools inside Earth, it forms igneous rocks like granite or basalt. The cooling process can result in different textures, such as fine-grained or coarse-grained, depending on whether the magma cooled quickly or slowly.
What will form when magma cools?
When magma cools, it can solidify into different types of igneous rock depending on the cooling rate. Slow cooling can form coarse-grained rocks like granite, while rapid cooling can form fine-grained rocks like basalt. If the magma cools very quickly at the Earth's surface, it can solidify into volcanic glass like obsidian.
When magma cools rapidly what kind of textures does rock have?
Aphanitic, or fine-grained.
When magma cools quick is the crystal smaller or larger?
When magma cools quickly, the crystals that form are typically smaller. This rapid cooling does not allow sufficient time for large crystals to grow, resulting in a fine-grained texture. Conversely, when magma cools slowly, larger crystals can develop due to the extended time available for crystal growth.
When magma cools above ground what will it crystallize?
When magma cools above ground, it will crystallize into fine-grained igneous rocks such as basalt. The quick cooling process prevents large crystals from forming, resulting in a texture that is smooth and not easily visible to the naked eye.
What includes the formation of igneous rock from magma?
The formation of igneous rock from magma involves the cooling and solidification of molten rock material. When magma rises to the Earth's surface or cools within the crust, it loses heat and gradually solidifies, forming crystalline structures. If it cools quickly, such as during a volcanic eruption, it can create fine-grained rocks like basalt; if it cools slowly underground, it forms coarse-grained rocks like granite. This process is a fundamental part of the rock cycle.
What is the origin of the fine grained igneous rock?
Uplift and solidification
Are in intrusive rocks fine grained?
No, intrusive rocks are typically coarse-grained because they form from magma that cools slowly beneath the Earth's surface, allowing larger crystals to develop. In contrast, extrusive rocks, which form from lava that cools quickly on the surface, are usually fine-grained. Thus, the grain size is a key distinguishing feature between intrusive and extrusive igneous rocks.
How do fine grain igneous rock form?
Fine-grained igneous rocks form when the magma cools quickly.
What are the properties of extrusive rock?
Extrusive rocks are formed from magma that cools quickly on the Earth's surface, resulting in small or no crystals. They typically have a fine-grained texture and may contain gas bubbles. Examples of extrusive rocks include basalt and rhyolite.
Which rocks are extrusive igneous rocks where do they form?
Extrusive igneous rocks are formed when magma reaches the Earth's surface and cools. Since this magma is exposed to air and/or water, it cools very quickly, creating finer-grained, sometimes glassy rocks. Obsidian and pumice are both extrusive igneous rocks. Conversely, intrusive igneous rocks, like granite, are created when magma cools in the Earth's crust, which is a slower process.
Where do coarse-grained igneous rocks form?
Coarse-grained igneous rocks are formed when magma cools slowly deep inside the Earth. Creating big crystals in them.
