magma

Definition

Magma is hot, melted rock that is found inside the Earth. It is made up of liquid rock, dissolved gases, and suspended crystals. Magma can be found deep underground, or it can erupt onto the surface of the Earth during a volcanic eruption.

Magma is formed when rocks deep inside the Earth are heated up. The heat causes the rocks to melt, and the dissolved gases and suspended crystals are released. Magma can also be formed when two different types of rock collide.

When magma erupts onto the surface of the Earth, it is called lava. Lava is still hot and molten, but it is exposed to the air and it starts to cool and solidify. Lava can flow for miles, and it can create new landforms, such as volcanoes and mountains.

Etymology

The word "magma" comes from the Latin word "magma", which means "thick mass". It was first used in English in the 17th century.

The Latin word "magma" is thought to be derived from the Greek word "μάζα", which also means "thick mass". The Greek word "μάζα" is related to the verb "μάσσειν", which means "to knead". This is a reference to the way that magma is constantly moving and changing, like dough being kneaded.
