What is the streak color of basalt?
Basalt typically has a dark gray to black streak color.
Which rock has a darker color basalt or granite?
Basalt tends to be darker in color compared to granite. Basalt is typically a dark-colored volcanic rock formed from the rapid cooling of lava, while granite is an igneous rock that is lighter in color due to its composition of lighter minerals such as quartz and feldspar.
Streak color of basalt?
Basalt is typically a dark gray to black in color due to the high content of iron and magnesium minerals. This gives it a consistent streak color of dark gray to black as well.
What is the color and the type of rock that forms oceanic crust at mid ocean ridges?
The color of rock that forms oceanic crust at mid-ocean ridges is usually dark gray to black. The type of rock is basalt, which is rich in iron and magnesium and forms from solidified lava.
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.
Which has a lighter color rhiolite or basalt?
rhyolite
Is basalt an example of a felsic rock?
No, basalt is not an example of a felsic rock. Basalt is an example of a mafic rock, which is rich in iron and magnesium and typically dark in color. Felsic rocks, on the other hand, are rich in silica and aluminum and are lighter in color.
What is the streak color of basalt?
Basalt typically has a dark gray to black streak color.

Streak color of basalt?
Basalt is typically a dark gray to black in color due to the high content of iron and magnesium minerals. This gives it a consistent streak color of dark gray to black as well.
What is the dark color rock that makes up the most of the oceanic crust is?
Basalt.
What is the color and the type of rock that forms oceanic crust at mid ocean ridges?
The color of rock that forms oceanic crust at mid-ocean ridges is usually dark gray to black. The type of rock is basalt, which is rich in iron and magnesium and forms from solidified lava.

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 is a mafic rock and what color is it?
Mafic rocks are igneous rocks that are rich in magnesium and iron minerals. They typically appear dark in color, ranging from black to dark green. Examples include basalt and gabbro.
What gives basalt its dark color?
Andesite gets its dark colour from the way its crystals stick together.
What does basalt mean in science?
In science, basalt refers to a fine-grained volcanic rock that is dark in color and commonly found in oceanic crust. It is formed from the rapid solidification of lava and contains minerals such as feldspar, pyroxene, and olivine. Basalt is important in Earth's geology and can provide insights into the history of volcanic activity.
How does a basalt differ from gabbro?
Basalt is a fine-grained volcanic rock, usually dark in color, while gabbro is a coarse-grained intrusive rock that is also dark in color. Basalt tends to cool and solidify quickly on the Earth's surface, resulting in a fine-grained texture, whereas gabbro cools slowly beneath the surface, allowing larger mineral crystals to form.
