Magma
VOLCANISM
An opening in the Earth's crust where melted rock reaches the surface is called a volcano.
If it reaches the surface, it is magma or lava. If it merely intrudes into rocks already formed, it is intrusive. Such as sills and dikes.
Molten rock above ground is called lava. It is molten rock that flows out of a volcano during an eruption and cools to form solid rock. Lava can vary in temperature, viscosity, and composition depending on the type of volcano.
Igneous rock is formed from cooled melted rock. It can be further classified as intrusive (formed below the earth's surface) or extrusive (formed on the earth's surface). Examples include granite, basalt, and obsidian.

Melted rock below the eaths suface is magma
'Magma' is melted rock occurring under the Earth's surface. When it comes up and flows out on the Earth's surface it is called 'lava'.
Melted rock below Earth's surface is known as magma. Magma forms when rocks in the Earth's mantle melt due to high temperatures and pressure. As magma rises towards the surface, it can eventually erupt as lava through a volcano.
Melted rock beneath the earth is called magma.
Melted rock beneath Earth's surface is known as magma. Magma forms in the Earth's mantle and can rise to the surface, where it is then called lava. Magma can also cool and solidify beneath the surface, forming igneous rocks.
An opening in the Earth's crust where melted rock reaches the surface is called a volcano.
If it reaches the surface, it is magma or lava. If it merely intrudes into rocks already formed, it is intrusive. Such as sills and dikes.
The molten rock inside the Earth is called magma. When magma reaches the surface, it is called lava.
Molten rock above ground is called lava. It is molten rock that flows out of a volcano during an eruption and cools to form solid rock. Lava can vary in temperature, viscosity, and composition depending on the type of volcano.
Molten material below the surface of the Earth is called magma. It consists of molten rock, gases, and suspended solids. Magma can eventually erupt onto the Earth's surface as lava through volcanic activity.
Igneous rock is formed from cooled melted rock. It can be further classified as intrusive (formed below the earth's surface) or extrusive (formed on the earth's surface). Examples include granite, basalt, and obsidian.
