What else can I help you with?
What molten rock is under the surface?
Molten rock beneath the surface is called magma. It can form in the Earth's mantle and rise to the surface during volcanic eruptions. Magma can vary in composition, temperature, and viscosity depending on the location and geological conditions.
Is silica a type of gas in a volcano?
No. Silica, or silicon dioxide, is a component of magma and most rocks on earth. It is a solid under most conditions but will form part of the liquid melt of magma. Pure silica in mineral form is called quartz.
Why do rocks form?
Igneous rocks form because, magma cools under the ground, or magma erupts, then cools on the ground forming these rocks.
What does low silica magma form?
Nealy all magma on Earth is originally low-silica, mafic magma. Most magma originates from the upper mantle, which is ultramafic, meaning it has a very low silica content. This rock may partially melt under certain conditions, forming mafic magma, which has a somewhat higher silica content than the mantle rock.
If the heat and pressure inside earth cause a rock to melt what material would be formed?
If heat and pressure inside the Earth cause a rock to melt, the resulting material would be magma. When magma cools and solidifies, it can form igneous rock. The composition of the magma depends on the original rock material and the conditions under which it melted.
When magma does crystallization what rock does it make?
That entirely depends on what type of magma it is and under what conditions it crystallizes. If you are looking for a general rock type, the answer is igneous, but that's very general.
What happenes during each method to form intrusive igneous rocks?
Igneous rocks are formed under high heat conditions. Intrusive igneous rocks are formed by the crystallization of magma in the Earth's crust.
Why rocks are differ?
Because of how they form and what conditions they form under.
How can magma form beneath volcanoes?
Magma is hot liquid lava that erupts out of a volcano, it's already under the entire surface of the Earth. In areas where the crust is weak, that's where the magma forms.
Molten rock under the ground?
Molten rock under the ground is called magma. It is formed from the melting of rocks in the Earth's mantle. Magma can rise to the surface through volcanic eruptions, or it can solidify underground to form igneous rock.
Where one tectonic plate is pushed under another magma forms and rises toward the surface form where the magma erupts as lava that builds up?
valcano
What factors affect the size of the crystals that form as magma cools?
it depends on how long is ban under the ground
