How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
The mineral composition of the oceanic crust is similar to the composition of what rock?
The mineral composition of the oceanic crust is similar to the composition of basalt rock. Basalt is a type of volcanic rock that contains minerals such as feldspar, pyroxene, and olivine, which are also commonly found in the oceanic crust.
What do obsidian pumice rhyolite and granite have in common?
Obsidian, pumice, rhyolite, and granite are all types of igneous rocks that form from the cooling and solidification of molten material from within or on the earth's surface. They have different mineral compositions and textures based on their specific formation processes.
What is an extrusive igneous rock with a composition similar to granite but with smaller crystals?
An extrusive igneous rock with a composition similar to granite but with smaller crystals is called rhyolite. Rhyolite forms from the rapid cooling of magma at the Earth's surface, resulting in fine-grained crystals. It is light in color and rich in silica, similar to granite.
How are basalt and granite different in their Orgin texture and mineral composition and how are they similar?
Basalt is an extrusive igneous rock formed from the rapid cooling of lava, with a fine-grained texture and dark color due to high concentrations of iron and magnesium. Granite is an intrusive igneous rock formed from the slow cooling of magma underground, with a coarse-grained texture and lighter color due to its composition of quartz, feldspar, and mica. Both rocks are composed of silicate minerals, have crystalline structures, and are commonly used in construction and architecture.

Which layer in the Earth has a composition similar to the green olivine?
The Earth's upper mantle has a composition similar to the green mineral olivine. Olivine is a common mineral found in the upper mantle, making up a significant portion of its composition.
What is an igneous rock that cooled very quickly called?
An igneous rock that cooled very quickly is called a volcanic glass, such as obsidian. These rocks lack a crystalline structure due to rapid cooling, resulting in a more glass-like texture. Their composition is similar to that of other igneous rocks but with a characteristic lack of defined mineral grains.
What is a dark coarse-grained intrusive igneous rock similar to basalt in mineral make up?
Gabbro

What is coarse grained igneous but not granite?
Gabbro is a coarse-grained igneous rock that is different from granite. It forms from the slow cooling of magma deep within the Earth's crust and is composed mainly of dark-colored minerals like pyroxene and olivine. Gabbro typically has a similar coarse texture to granite but has a darker color due to its mineral composition.
How are basalt and granite different in their Orgin texture and mineral composition and how are they similar?
Basalt is an extrusive igneous rock formed from the rapid cooling of lava, with a fine-grained texture and dark color due to high concentrations of iron and magnesium.

A rock that consists mostly of mineral quartz will have a composition very similar to?
Quartz is a major mineral in granite. Therefore, a rock consisting mostly of quartz will have a composition similar to granite. Both rocks are light in color and have a high silica content.
How are the sultan granite different in their Orgin texture and mineral composition and how are they similar?
They are massive, hard and tough in nature. They may resemble each other in terms of color and texture.
What is a dark coarse-grained intrusive igneous rock similar to basalt in mineral make up called?
The answer is Gabbro.
