Differences Between Magma and Lava

One must understand the difference between Magma and Lava to fully grasp the meanings between one and the other. As they are both molten rock that emerges from below the Earth. It can get confusing identifying one from the other. Lava can be defined as the hot molten rock that gets shot out of the surface of the Earth, this is a semi-solid, burning hot substance that comes out of the Earth’s surface. The temperatures at which the molten lava usually vary however, they range from 1300-2200 degrees. Lava is usually categorized based on a number of different factors such as the viscosity and composition of the lava that spews out. It is important to know the types of volcanoes from which this type of lava may emerge.

Difference between Magma and Lava

Magma on the other hand is more of a molten rock that contains volatile substances within it. These substances usually lie below the surface of the Earth itself. Magma usually contains itself within magma chambers. These chambers usually contain a collection of dissolved gases, suspended crystals and gas bubbles. The heat that is produced within Magma may range from a temperature between 1300 and 2400 degrees.

Difference between Magma and Lava

Magma

Lava

The molten rock that is present beneath the surface of the earth is termed as Magma.

The molten liquid that gets erupted out of the surface of the Earth is termed as Lava. Lava is also referred to as Liquid Magma.

The temperature of Magma is slightly hotter and ranges from 1300-2400 degrees Fahrenheit.

The temperature of Lava is slightly colder and ranges between 1300-2200 degrees Fahrenheit.

The word Magma has its origins from Ancient Greek.

The word Lava has its origins from the Italian Language.

Lava has the property of cooling much quicker than Magma. This leads to lava sometimes crystalizing into glass.

Magma on the other hand takes a much longer time in cooling, as it is located underground which leads to the creation of gigantic crystals.

Thus, this is the key difference between Lava and Magma. If you liked this article and would like to read more download the BYJU’s app today! You may also want to check our related links below:
