There are three basic types of magma: basaltic, andesitic, and rhyolitic, each of which has a different mineral composition. The volcanoes that emit ash, gas and magma high into the sky are known as 'explosive volcanoes', while those which emit lava are termed as 'effusive volcanoes'. Magma is the molten form of rock, stored deep beneath the Earth's surface. Magma is the molten or semi-molten natural material from which all igneous rocks are formed. This type of magma has the highest silica and gas content. ta [mag-muh-tuh]. Once it comes to the surface, it is known as lava. The main vent is the main outlet for the magma to escape. This, in turn, produces an intermediate composition of the same. Answer for question: Your name: Answers. When the denser plate subducts below the less dense plate, hot rocks from below rises into the cooler areas above the subducting plate resulting in the formation of magma. That is because once it reaches the surface it becomes lava. magma made of 3 components. 1 decade ago. Magma generated by the hot spot rises through the rigid plates of the lithosphere and produces active low viscosity volcanoes at the Earth's surface. 49 50 51. When a volcano erupts or a deep crack … Magma contains a mixture of gases and simple elements. Magma is primarily a very hot liquid, which is called a 'melt.' Researchers also believe that magma exists on other terrestrial planets in and beyond our solar system. Suspended crystals and fragments of unmelted rock may be Magma migrates either at depth or to Earth’s surface and is ejected as lava. Chemically lava is made of the elements silicon, oxygen, aluminum, iron, magnesium, calcium, sodium, potassium, phosphorus, and titanium (plus other elements in very small concentrations. Wiki User Answered . Magma, basically the derivative of molten rocks. A magma chamber is a large pool of liquid rock beneath the surface of the Earth. Relevance. This mixture is usually made up of four parts: a hot liquid base, called the melt; minerals crystallized by the melt; solid rocks incorporated into the melt from the surrounding confines; and dissolved gases. Magma is extremely hot, melted rock, but it also contains other materials. Magma is molten rock within Earth that consists of liquids, gases, and particles of rocks and crystals. Magma is a mixture of molten and semi-molten rocks, crystallized minerals, solids, and dissolved gases. As it makes its way up, it melts the rock structures surrounding the upward flow and integrates the elements present in them. It also contains small amounts of dissolved gases such as water vapor, carbon dioxide, and sulfur. Answer. When magma is ejected to the surface through volcanicity it is known as lava. The word ‘lava’ is obtained from the Latin word ‘labes’ that stands for a fall or slide. It also has a low content of gas and viscosity. Magma is composed of molten rock and is stored in the Earth’s crust. Magma can mix with an existing body of magma. In this story, we will try to answer one of the basic questions in the field of geological studies, what is magma made of? For example, it usually contains bits and pieces of minerals that have not yet melted or have solidified (or cr… The molten material, which already exists in the outer core of the planet, travels to the other parts through cracks and fissures. It flows over the surface of the earth. Magma is primarily made up of elements like: As the amount of oxygen and silica in the molten matter is high, it is ideal to classify it into different types depending on its silica content. Mafic magma does not erupt explosively but it instead flows out of volcanoes and moves quickly on the surface. The high temperatures and pressure under Earths crust keep magma in its fluid state. The temperature of this hot fluid ranges from 1292 - 2372 °F. Lava is molten rock that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon.Magma is generated by the internal heat of the planet or moon and it is erupted as lava at volcanoes or through fractures in the crust, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F).The volcanic rock resulting from subsequent cooling is also often described as lava. What magma made from? earth is like a boiled egg. At this temperature, it has the ability to melt the surrounding rock structures to produce more magma. Its temperature is between 1472° to 1832° Fahrenheit resulting in a higher viscosity than mafic magma. Asked by Wiki User. Enormous heat, which is sufficient enough to melt the rocks, is also generated when two huge rock masses rub against each other.
