Which type of rock forms from magma?
magma is a mixture of several different types of rock.
How are silica and water related to volcanos explosiveness?
because
What type of rock forms from sediment of different materials such as sand dirt mud clay gravel and stone?
Sedimentary rock - these are usually recognisable by their layers.Other types of rock include:Igneous rock - formed when magma cools, recognisable by their crystals scattered insideMetamorphic rock - rock which has been pressurised and heated, altering it.
What does continental- continental collision cause?
The oceanic plate is forced to sink beneath the continental plate as it is denser. This is subduction. From here, a further series of events unfolds (if you are still interested)...The material is melted into magma at the pressure and heat intensityThe magma rises due to convection (warmer rises above cooler)The fold mountains formed due to the pressure of two plate colliding now spring arise to volcanoes as the lava comes upThe volcanoes are of an Acidic lava type, even though the origin of the rock is the basaltic sea floor (you might expect 'Basic' lava). This makes them highly explosive, and have infrequent eruptions. Why is this?The volcanoes formed are explosive because the lava is very viscous as it has a high silica content. This is because of the sediment which was also subducted with the crustal rock. When the magma pushes up, it often cools quickly within the cone of the volcano, forming a plug. When the pressure of the magma is too great, the volcano explodes, like the spectacular eruption at Mt. St. Helens in September 1980.With this collision, you will also find many earthquakes occurring as friction occurs between the plates.
Which bond type is formed between two polar molecules that contain hydrogen?
a hydrogen bond
What is a type of rock formed when lava or magma cools?
the type of rock formed when lava or magma cools is igneous rock..
What type of rock is formed after volcanic magma cools?
If the magma cools on the surface of the crust, it is called extrusive igneous rock
Type of rock formed when lava or magma cools?
type of rock formed when lava or magma coolsIgneous Rock Forms when lava or magma cools.Trust Point me if this Helped, Thanks!
What does magma composition play a major role in?
The type of rock formed when the magma cools. The type of volcano or volcanic intrusion that is formed The explosiveness of volcanic eruptions.
What type of grains are formed when magma cools quickly at the surface of earth?
Small grains.
Which type of rock is formed when magma rises to the surface of the earth and cools?
uncategorized
What type of rock is formed by cool lava or magma?
An igneous rock is formed when magma cools and hardens. Some examples of igneous rocks are pumice and obsidian.
What is a type of rock formed by cooled magma?
Igneous rock is formed from the solidification of magma as it cools.
What type of crystal texture is formed when magma cools slowly within warm rock underground?
As magma cools slowly, large coarse crystals form. This is described as a phaneritic texture.
What type rock forms when magma cools and hardens?
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
What are two factors affect the type of igneous rock that is formed?
The mineral composition of the magma and the rate at which it cools determines what rock forms.
What type of rock is formed by magma that cools deep below earths crust?
Igneous rocks are formed from cooled magma of lava, sedimentary rocks by sediment under pressure, and mettamorphic from any rock that undergoes much heat and/or pressure.
