A lava flow is an example of an igneous rock one of the two main igneous rock groups?
It is an example of extrusive igneous rock.
What else can I help you with?
When a volcano erupts lava may flow onto the surface. What type of rock does the lava cooling form?
When lava cools on the surface, it forms igneous rock called basalt.
Is scoria metamorphic?
no, extrusive because it is made by lava not magma.
Magma that has reached the earths surface?
When magma reaches the Earth's surface, it is called lava. Lava can flow out of a volcano during an eruption and can cool to form igneous rocks. The characteristics of the lava, such as its temperature and composition, can influence the type of volcanic eruption that occurs.
Where would you expect to find the largest crystals in a lava flow?
The largest crystals in a lava flow can typically be found in the center or core of the flow where cooling occurs more slowly, allowing for more extensive crystal growth. These areas are often shielded from rapid cooling by the outer crust of the flow.
Which type of rock is formed above the ground by lava?
The general type is extrusive igneous rock.
What type of igneous rock is a lava flow an example of?
It is an example of extrusive igneous rock.
A lava flow is an example of what?
A geologic event. An example of an igneous rock formation.
What is another name for an extrusive igneous rock?
Basalt is one example. or perhaps a lava flow or an ignimbrite.
How can lava flow from a volcano and become part of the rock cycle and eventually become a flow of lava again?
The lava is melted rock called magma when it is underground, then it is exposed and is then called lava. The volcano erupts, and it hardens into igneous rock. If the igneous rock heats up again, it is lava once more!
Lava is an example of what kind of rock?
Lava flows in Hawaii are an example of Mafic Lava. Mafic Lava is composed of Basaltic rocks of which tend to have high levels of iron and magnesium.
What types of rocks are formed from a quickly cooled lava flow?
Cooled lava produces extrusive igneous rock.
The lava flows of hawii are an example of what kind of rock?
igneous rock
If a lava flow at earths surface had a basaltic composition what rock type would the flow likely be?
A Mafic Extrusive Igneous Rock.
When a volcano erupts lava may flow onto the surface. What type of rock does the lava cooling form?
When lava cools on the surface, it forms igneous rock called basalt.
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.
Is lava metamorphic?
No. Lava is igneous.
Is scoria metamorphic?
no, extrusive because it is made by lava not magma.
