What type of mountains are formed when molten rock erupts onto earth surface?
volcanic mountains
Where do most rocks have basaltic composition?
Most rocks with basaltic composition are found in volcanic regions, such as volcanic islands and mid-oceanic ridges. They are also commonly found in continental flood basalt provinces, which are large expanses of basaltic lava flows that cover extensive areas of land. Basaltic rocks can sometimes be found in other settings as well, such as in certain types of metamorphic rocks.
Does volcanic mountains build from layers of ash cinders and lava erupting onto the earth's surface?
Yes
Volcanic mountains build from layers of ash cinders and lava erupting onto the earth's surface.?
true
What is the composition of lava?
Lava is made up of volcanic glass, volcanic gases, and crystals. Once the magma arrives near the surface and starts to cool, it crystallizes the minerals and forms volcanic gases.

What us the surface of volcanic mountains made of?

What are mountains formed by magma that reach the Earth's surface?
Mountains formed by magma that reach the Earth's surface are called volcanic mountains or ridges.

Are seamounts volcanic?
Yes, volcanic seamounts are the submarine mountains that haven't reacher the surface of the water. When they do, they become islands.
