Lava.
Hot magma outside a volcano is called lava. Lava is molten rock that flows out of a volcano during an eruption.
Hot liquid rock is called magma when it is beneath the Earth's surface and lava when it reaches the surface through a volcano.
Lava
Hot lava comes from effusive eruptions, where magma is relatively low in silica and flows easily out of the volcano. This type of eruption typically results in slow-moving lava flows that can cover large areas.
Hot liquid rock exposed at the Earth's surface is called lava. It forms when magma erupts from a volcano and solidifies after cooling down, creating different types of volcanic rocks. Lava flows can vary in viscosity, temperature, and composition, leading to different types of eruptions and volcanic landforms.
The is called "lava", before it comes out on the surface it is called "magma".
The igneous rock forms from lava because when a volcano erupts the lava that flows from a volcano. Igneous rocks have a hot liquid in the beginning. The lava that flows forms into an igneous rock fast. When the lava reaches the surface, it cools rapidly and turns into igneous rock.
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.
Lava is melted rock that comes from the volcano.
Lava or Magma.
When magma beneath Earth's surface is forced up due to pressure, it flows out to Earth's surface through openings.
After erupting from a volcano, hot lava flows down the volcano's slopes or it may create lava flows that spread over the surrounding area. As the lava cools, it solidifies into rock formations called igneous rocks. Over time, these rocks can weather and break down to form new soil.
