What is the difference between lava and magma Which is hotter magma or lava

Magma is formed on the ground, while lava works on the earth's crust.

MagmaThe temperature is usually between 700 and 1200 degrees. But the temperature of the magma of different compositions in Hail Mingqing is different: The temperature of basalt magma is higher, up to 1025 to 1225 degrees; andesite magma is 900 1000 degrees; The temperature of the acid-sourced magmatic locust bend is the lowest, generally 735 890 degrees.

Lava that flows on the surface in a liquid state is called a lava flow, and when the lava flow cools, it forms a solid rock accumulation, sometimes called a lava flow. The temperature of lava flowing in liquid form is usually between 900° and 1200°C.

Extended information: Magma temperature is related to a variety of factors, which can be determined directly from lava flows from modern volcanoes or by indirect methods. The temperature of magma is usually between 700 and 1200 degrees Celsius, according to the direct determination of volcanic lava flows and the study of lava melting and crystallization temperatures.

Magma is a high-temperature melt deep underground, with a complex composition dominated by silicates, containing large amounts of water vapor and other volatile substances. It is a variety of magmatic rocks and related deposits**.

There is also an explanation that magma refers to rocks that are molten or partially molten underground. When magma erupts from the earth's surface, it is called lava. The magma that erupts from the surface becomes the ejecta rock; Intrusions into the earth's crust are called intrusive rocks.

Evolution

The basic process of magmatic evolution is the formation of a variety of magmatic rocks from a small number of magmas through differentiation, assimilation and mixing.

There are two main types of differentiation: melting and crystallization.

Melting refers to the division of originally homogeneous magma into two immiscible magmas as the temperature and pressure decrease or due to the addition of foreign components. Sulfides, oxides and silicate melts in natural magma can be dissociated.

The crystallization temperature of minerals varies from high to low, so the order of crystallization and precipitation of minerals from magma is also precedent, which is crystallization differentiation.

Assimilation is also known as assimilation and mixed dyeing. Due to the high temperature of magma and its strong chemical activity, it can melt or dissolve the surrounding rock that comes into contact with it or the surrounding rock blocks it captures, thus changing the composition of the original magma.

If the magma completely melts or dissolves the surrounding rock to make it completely uniform with the magma, it is called assimilation; If the melting or dissolution is not complete, the traces of the surrounding rock are retained to varying degrees (such as specimen structures, etc., it is called mixed dyeing. Because assimilation and mixed dyeing often coexist, it is also collectively referred to as assimilation and mixed dyeing.

Magma means hot magma formed by the melting of underground rocks, which is in the ground before it erupts to the surface.

Lava is volcanic rock formed by magma erupting from the earth's surface.

Magma is the parent body of meltdown excavations, which erupt from the surface to form volcanic rocks, including lava (e.g., basalt, rhyolite) and clastic rocks (e.g., tuff); Those that have not erupted from the surface are called intrusive rocks, such as granite, which we often say, and the two are collectively called igneous rocks. That is, igneous rocks are all formed from magma. The big fight point is that our crust down to the core is all magma.

This means that magma is the parent lava eruption rock, and the silver core lava is a type of rock formed by the eruption of underground magma from the earth's surface.

We call molten material that is produced deep in the upper mantle and crust and contains volatile components, mainly silicates, as magma.

Magmatism refers to a series of changes in the magma itself and its impact on the surrounding rock in the whole process of magma formation, movement and condensation into rocks. Magmatism is another manifestation of the outward release of energy from within the Earth. Magmatism can be divided into extrusion and intrusion.

The magmatic rocks formed accordingly are called volcanic rocks and intrusive rocks, respectively.

Magma, a geological term, is a molten fluid formed in the upper part of the earth's mantle, which is composed of four parts: the liquid formed by melting, the crystallized minerals in the liquid, the traps and inclusions, and the dissolved gas in the magma.

Magma is divided into primary magma and regenerated magma, which can be transported to different depths of the earth's crust with crustal activities to condense and crystallize, or can be ejected to the surface for condensation and consolidation.

During the eruption of lava flows, a large amount of volatiles will be lost due to the sudden drop in pressure, so it is not really magma, but only the material closest to magma. Magma can move to different depths of the earth's crust with crustal activity to condense and crystallize, or it can spill to the surface to condense and consolidate. The whole process from the generation of magma to the rise to the condensation and consolidation of magma into rock is called magmatic activity or magmaticaction, and the magmatic activity that erupts from the surface is called volcanism or volcanism.

Magma turns into lava when it comes into contact with air.
