How will the size of crystals in granite be different to the size of crystals in basalt?
Yes, because granite is a slow cooling rock, therefore the crystals have a lot of time to form, while basalt is a fast cooling rock, therefore thecrystals don't have much time to form and develop larger.
the granite is crystallising below the surface and have more time for crystallisation where basalt crystallizing on the surface and rapidly crystallizing so this why fine grain.

Basalt has a greater specific gravity than granite?
Basalt typically has a higher specific gravity than granite due to its more dense and heavy composition. This means that basalt is usually heavier for its size compared to granite.
What size are the crystals in marble?
The crystals in marble can vary in size, but they are typically small to medium in size, typically ranging from a few millimeters to a few centimeters. Marble is a metamorphic rock primarily composed of calcite or dolomite crystals that give it its characteristic appearance.
How big are basalt crystals?
Basalt crystals are typically microscopic in size, ranging from a few microns to a few millimeters. Under ideal conditions, some basalt crystals can grow larger, reaching centimeter-scale.
Is granite crystal or grain size?
Granite is a type of igneous rock that is composed of large crystals of minerals like quartz, feldspar, and mica. The crystals in granite can vary in size, ranging from small to very large, depending on the specific conditions under which the rock formed.
What determines the size of crystals that form in granite?
The cooling rate of magma plays a significant role in determining the size of crystals.
How willl the sizen of crystals in granite b different from the size of the crystals in basalt?
The will be large in an extrusive granite and fine in an intrusive basalt.
What rock has larger crystals than basalt and granite?
A pegmatite is a rock formed under certain favorable circumstances that enhance the crystal size of the rock. The crystals would be larger than those in basalt, an extrusive igneous rock, and granite, and intrusive igneous rock.
What is the size of basalt crystals?
relativity small

The crystals in marble can vary in size, but they are typically small to medium in size, typically ranging from a few millimeters to a few centimeters. Marble is a metamorphic rock primarily composed of calcite or dolomite crystals that give it its characteristic appearance.
What is the size of crystals in granite?
Crystals in granite can vary in size, but typically range from 1 mm to several centimeters in diameter. The size of crystals is influenced by factors such as the rate of cooling of the magma and the mineral composition of the granite.
Are basalt crystals large in size?
Basalt crystals are typically small to microscopic in size due to the rapid cooling of lava, which results in limited time for crystal growth. This rapid cooling process usually prevents the development of large crystals in basalts.
What are the size of granite crystals?
Granite crystals vary in size, but they are typically between 1-10 millimeters in diameter. Larger crystals can also be found in some granite formations, reaching up to several centimeters in size.
How big are basalt crystals?
Basalt crystals are typically microscopic in size, ranging from a few microns to a few millimeters. Under ideal conditions, some basalt crystals can grow larger, reaching centimeter-scale.
What is basalt crystal size?
Basalt typically has a fine-grained crystal size, usually referred to as aphanitic, meaning the crystals are too small to be seen with the naked eye. This results in a smooth or glassy texture in basalt rocks.
State one observable characteristic other than crystal size that makes granite different from basalt?
Granite is typically light in color due to its high silica content and contains visible grains of minerals like quartz, feldspar, and mica. In contrast, basalt is typically dark in color, fine-grained, and contains minerals like pyroxene and olivine.
What are rocks that have visible crystals in them classified as?
Rocks with visible crystals are classified as crystalline rocks. These rocks are formed when minerals inside the rock crystallize and grow to a size that they are visible to the naked eye. Examples include granite and basalt.
