Under the basalt layer, you would typically find gabbro, which is a coarse-grained igneous rock formed from the same magma that cools slowly beneath the Earth's surface. Additionally, in some geological settings, you might encounter sedimentary rocks or metamorphic rocks, depending on the specific tectonic and environmental history of the area. If the basalt is part of an oceanic crust, it may also rest on peridotite, a mantle rock.
What else can I help you with?
The floor of heavier rock under the oceans is composed of?
The floor of heavier rock under the oceans is primarily composed of basalt. Basalt forms from volcanic activity and makes up the majority of the oceanic crust.
What is the dark colored rock the makes up most of the oceanic crust?
Basalt
Where in Earth's crust would you find basalt?
Most basalt is found in the oceanic plates. Most granite is found in the continental plates.
If a lava flow at Earth's surface had a basaltic composition what rock type would the flow likely turn into upon solidification?
It would form into the rock basalt, an extrusive, mafic, igneous rock.
What is the crustal portion of each oceanic plate is composed primarily of?
Basalt rock with a layer of sedimentary rock overlaying that, covered with water saturated sediments.
What is the most abundant extrusive rock exposed layer upon layer at the Grand Candyon?
basalt
Which layer of rock would be most under pressure?
The deeper layer.
The floor of heavier rock under the oceans is composed of?
The floor of heavier rock under the oceans is primarily composed of basalt. Basalt forms from volcanic activity and makes up the majority of the oceanic crust.
Is basalt a igneous metamorphic or sedimentary rock?
Basalt is an extrusive igneous rock.
What is a fossil found under a layer of rock is usually?
It is usually older than the rock layer it is found under.
What is A fossil found under a layer of rock is usually .?
It is usually older than the rock layer it is found under.
What is the dark colored rock the makes up most of the oceanic crust?
Basalt
Where in Earth's crust would you find basalt?
Most basalt is found in the oceanic plates. Most granite is found in the continental plates.
Which is the layer of solid rock that is found under all soil?
Bedrock. However you should realize that sometimes bedrock can be over a thousand feet below the soil. For example, on the coastal plains of the US, bedrock can be a few feet deep, or several thousand.
What was the basalt and igneous rock formed by?
Basalt and igneous rocks were formed by what we would call magma/lava
How would you connect the words lava and basalt?
Most lava forms a rock called basalt when it cools.
If a lava flow at Earth's surface had a basaltic composition what rock type would the flow likely turn into upon solidification?
It would form into the rock basalt, an extrusive, mafic, igneous rock.
