What are extrusive and intrusive igneous rock?
Extrusive rocks are formed outside of earths surface. Intrusive rocks are formed inside earths surface.
What is Magma reaching earths surface flows from a volcano as blank?
Magma that reaches the Earth's surface flows from a volcano as lava. When magma erupts through a volcano, it becomes lava, which can flow in various forms, such as basaltic, andesitic, or rhyolitic, depending on its composition. As lava cools, it solidifies and can form different types of volcanic rock.
Which changes occur in the composition of the earths layers from the surface to the core?
material is hotter and denser
The basaltic rock that forms volcanic mountains where mantle plumes reach earths surface is usually composed of what?
The basaltic rock that forms volcanic mountains where mantle plumes reach the Earth's surface is typically composed mainly of silicate minerals, particularly pyroxene and plagioclase feldspar. It often contains smaller amounts of olivine and iron-rich minerals. This composition gives basalt its characteristic dark color and low viscosity, allowing it to flow easily during volcanic eruptions.
Type of igneous rock which is formed when magma underneath the earths surface solidifies and hardens?
Well, there are a few formations ; sills, loccoliths, lopoliths, dykes, layered igneous intrusions and batholyths.
If a lava flow at earths surface had a basaltic composition what rock type would the flow likely be?
A Mafic Extrusive Igneous Rock.

Where do you experience more gravity on earths surface or earths center?
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.
What mineral is stable at earths surface?
Quartz is a mineral that is stable at Earth's surface due to its chemical composition and resistance to weathering processes.
Why is earths composition of earths atmosphere important?
The Chemical Composition of the Earth's atmosphere is important because it holds the Earth together.
What percent of the earths surface is the US?
100
How much of earths oceans cover earths surface?
70% or 80% of water covers the earths surface
Does the outer core cover earths surface?
No the crust covers earths surface
Why are map projecters needed?
to draw the earths surface.
