When magma cools in two stages, it typically results in a texture known as porphyritic. In the first stage, magma cools slowly underground, allowing large crystals to form, known as phenocrysts. In the second stage, the magma erupts and cools rapidly at the surface, leading to a fine-grained matrix. This combination creates a rock with a distinct texture, featuring visible larger crystals set within a finer-grained background.

Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
What are the 2 ways igneous rock are is formed?
Igneous rocks are formed through volcanic activity, where molten rock (magma) cools and solidifies either on the Earth's surface (extrusive igneous rock) or beneath the surface (intrusive igneous rock). These cooling processes result in the formation of crystals within the rock, determining its texture and composition.
What three factors affect the formation of magma?
Three factors that affect the formation of magma are temperature, pressure, and the presence of volatiles (such as water and carbon dioxide). Increasing temperature, decreasing pressure, and the addition of volatiles all contribute to the melting of rocks and the formation of magma beneath the Earth's surface.
What are the 3 stages in the formation of volcano?
When a continental plate and an oceanic plate move toward each other and collide, the edge of the oceanic plate goes down into the part of the mantle which consists of molten rocks. At a depth of 125 to 160 km below the earth's surface, the heat is so great that the rock which goes down is partially melted. This partial melting of rocks generates magma. The downgoing rocks also brings water. The other materials in the mantle interact with the water and also generate magma. Magma has lower density than the surrounding rocks. The gas from the melting rock which mixes with the magma makes it rise. As magma rises, it melts its way through the surrounding rocks and forms a large chamber where magma is stored until it finds it way out to the earth's surface.
What are the 3 stages of a volcanoe?
The three stages of a volcano are: 1) precursory stage, where signs like earthquakes and ground deformation occur, indicating magma movement beneath the surface, 2) eruptive stage, where the volcano releases ash, lava, and gases, and 3) post-eruptive stage, where the volcano gradually becomes dormant again.
Magma cooling in 2 stages slow and then fast what is the resulting texture?
The resulting texture is porphyritic. The slower cooling stage allows large crystals to form (phenocrysts), while the faster cooling stage results in the formation of smaller crystals in the remaining magma (groundmass). This gives the rock a mixture of large and small crystals, creating a porphyritic texture.

How are the 2 types of igneous rock made?
They are either made through the fast cooling of lava, or the slow cooling if magma in the Earth.

What would happen if water was present in wet magma?
wet magma is nothing but magma which is cooling down.if wet magma touches water, it will cool down the magma.2. Much volcanic material, magma included contains water - hence forming clouds above an active volcano. But seldom is material ejected from the throat steaming when it lands, therefore most of the moisture is rapidly dissipated.Volcanic glasses can occasionally contain water, under large pressure and temperature, and upon the explosive ejection, may form pumice or ignimbrite.Presumably the water in the magma was entrained during the subduction phase of the cycle.
What determines how large the crystals and an igneous rock Will be?
The speed at which the magma/lava cools ie. fast cooling = not much time for crystals to form = little or no small crystals slow cooling = much time for crystals to form = big crystals
