Does a volcano form when magma reaches earths surface?
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
Does a mountin form when a volcano reaches the surface of the water in an ocean?
No, because when a volcano reaches the surface of the water it forms a volcnic island not a mountain
What substance reaches the earths surface that comes from a volcano?
lava
Can volcanoes form because of an earthquake?
Not really. Earthquakes can and do occur when a volcano is forming, but the volcano is not a result of an earthquake. Volcanoes are formed when magma (molten rock) within the earth's crust reaches the surface.
What do you call an opening in the Earth's crust where melted rock reaches the surface?
An opening in the Earth's crust where melted rock reaches the surface is called a volcano.
What does magma that reaches the surface flow out of?
it flows out of the central vent at the top of the volcano
What is called when magma erupts onto the surface of the volcano?
Lava. Because when magma reaches the surface, it is called lava.
Does a mountain turn into a volcano?
A volcano is formed when magma from beneath the Earth's crust reaches the surface through a vent or opening. While a mountain can be a volcano if it has been built up by volcanic activity, not all mountains are volcanoes.
What causes a volcano to grow larger?
When a volcano erupts, molten rock reaches the surface as lava, ash, or similar material. This is addes to the surface of the volcano. So the mountain or edifice of a volcano is essentially a pile of material that has erupted in the past.
What will be happen after magma form?
After magma forms, it will typically rise towards the Earth's surface due to its lower density compared to surrounding rock. As it reaches the surface, it may erupt as lava through a volcano or form intrusive igneous rock formations beneath the 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.
What materials are in a volcano?
Lava, or Magma as it is called before it reaches the surface is made out of molten rock.
