It is called magma before it hits the surface. Once it is on land it is called lava.
Melted material that rises from the mantle is called magma. Once magma reaches the Earth's surface, it is then referred to as 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.
It is called a volcano.
From near the Earth's core. The mantle, located beneath the Earth's crust, is where hot melted rock, known as magma, originates. This magma can rise towards the surface through volcanic activity.
Melted crust rises to the surface because it is less dense than the surrounding mantle material. Just like how hot air rises in a room, the buoyancy of the molten rock allows it to ascend through the solid rock above it. This process is known as mantle convection, where the hotter, less dense material moves upwards and the cooler, denser material sinks back down.
The opening in the earth crust which magma rise to the surface are Volcanoes
Buoyancy.
Rises
The channel through which magma rises within a volcano is called a conduit. This conduit allows magma to move from deep within the Earth up to the surface, where it can eventually erupt as lava.
The hot molten liquid that rises up through a volcano is called magma. It is a mixture of molten rock, gases, and other substances that is stored beneath the Earth's surface. When a volcano erupts, the magma is expelled as lava onto the Earth's surface.
it is called the art of materilintasion which was discovered by the neanderthals
The channel through which magma rises within a volcano is called the "magma conduit" or "volcanic conduit." This passage allows magma to move from the magma chamber beneath the Earth's surface to the surface, where it can erupt as lava. The size and shape of the conduit can influence the type and intensity of volcanic eruptions.
