What rock would form when basaltic magma cools?
When basaltic magma cools, it typically forms basalt rock. Basalt is a fine-grained, dark-colored volcanic rock rich in iron and magnesium minerals. It often contains characteristic minerals such as pyroxene, plagioclase feldspar, and olivine.
Is basalt a dark and green igneous rock?
Basalt is a dark-colored igneous rock that ranges from black to dark green in color. It is commonly found in volcanic areas and is rich in iron and magnesium minerals.
Volcanic islands in the deep ocean are composed primarily of what igneous rock?
Volcanic islands in the deep ocean are primarily composed of basaltic igneous rock, which is formed from the rapid cooling of lava. This rock is rich in minerals such as pyroxene, olivine, and plagioclase feldspar, giving it its characteristic dark color.
Is basalt an element a mineral or a rock?
Basalt is a rock composed of minerals which are composed of elements.
What type of type rock is basalt?
Basalt is an extrusive igneous rock, which means it has solidified from magma above ground.Read more: What_kind_of_rock_is_basalt

Is basalt a dark and green igneous rock?
Basalt is a dark-colored igneous rock that ranges from black to dark green in color. It is commonly found in volcanic areas and is rich in iron and magnesium minerals.
What type of rock makes up the dark spots on the Moon?
The dark spots on the Moon, known as lunar maria, are made up of basalt rock formed from ancient volcanic activity. Basalt is a dark-colored, fine-grained volcanic rock that is rich in iron and magnesium minerals.
What igneous rock has formed on earth surface?
Basalt is an igneous rock that commonly forms on the Earth's surface through volcanic eruptions. It is dark in color, fine-grained, and rich in iron and magnesium minerals. Basalt is found in oceanic crust, volcanic islands, and areas where lava has flowed.
How do you define basalt?
Basalt is a dark-colored igneous rock that forms from the solidification of lava flows. It is fine-grained and typically rich in minerals like pyroxene and plagioclase. Basalt is commonly found in volcanic regions and oceanic crust.
Does basalt react with acid?
Yes, basalt is a type of volcanic rock primarily composed of calcium-rich plagioclase feldspar and pyroxene minerals. It does react with acid, such as hydrochloric acid, by undergoing a chemical reaction that causes the dissolution of certain minerals in the rock and the release of gas bubbles.
What is the dark colored igneous rock with rich in iron and magnesium?
The dark-colored igneous rock rich in iron and magnesium is called basalt. Basalt is a fine-grained rock that is commonly found in volcanic areas and oceanic crust. It is characterized by its dark color due to the presence of minerals like pyroxene and olivine.
What color is basalt?
The rock basalt can be greenish, blackish, or gray.
Which has a greater percentage of biotite in it rhyolite or basalt?
Rhyolite typically has a greater percentage of biotite compared to basalt. This is because rhyolite is a silica-rich volcanic rock that contains more biotite, a mica mineral, which forms in silica-rich environments. Basalt, on the other hand, is a silica-poor volcanic rock that generally contains lower amounts of biotite.
Most common volcanic rock?
Basalt is the most common volcanic rock. It is a dark-colored, fine-grained volcanic rock that is found in many volcanic settings around the world. Basalt forms from the rapid cooling of magma on the Earth's surface.
Volcanic islands in the deep ocean are composed primarily of what igneous rock?
Volcanic islands in the deep ocean are primarily composed of basaltic igneous rock, which is formed from the rapid cooling of lava. This rock is rich in minerals such as pyroxene, olivine, and plagioclase feldspar, giving it its characteristic dark color.
What is an example of a mafic rock?
Basalt is a common example of a mafic rock. It is dark in color, fine-grained, and rich in minerals like pyroxene and olivine. Basalt is formed from the solidification of magma with low silica content, typically from volcanic activity.
