The heaviest rocks in the mantle do not directly become lava. Instead, they undergo processes such as partial melting due to increased temperature and pressure, which can produce magma. This magma can rise to the surface, where it may erupt as lava during a volcanic event. Thus, while the heaviest rocks contribute to the formation of magma, they do not transform into lava themselves.

How does lava flow become rock and then become a lava flow again?

It cools then it heats back up! Lava is molten rock (rock that is a fluid due to high temperatures). When lava cools, it becomes rock once again. Due to tectonic activity from the Earth's crust, rock can be shoved down into the mantle, which is extremely hot, which melts the rock once more. The whole process is analogous to water freezing to become ice, and then melting to become water once more.


What conditions allow rock in the mantle rock?

cause it will keep going until the lava stop erupting will make the mantle stop


What is hot molten rock under the earth's surface?

What is the liquid rock in the mantle called?

The liquid rock in the mantle is called magma. As it moves closer to the surface, it is then called lava when it erupts from a volcano.


How are lava form?

Lava is molten rock. The rock deep inside the earths mantle is always molten, and when it occasionally breaks through to the surface, the opening is called a volcano, and the liquid rock spilling out of the top is lava.


What is the name for magma flowing from a volcano?

Magma that flows from a volcano is called lava. Lava is molten rock that emerges from the Earth's mantle and reaches the surface during volcanic eruptions.


What does a rock become when it melts?

Lava.


When rock in earth's mantle melt what does it become?

Melted rock in the Earth's mantle is called magma.


Which layer of the earth produces lava and molten rock?

The mantle is the source of molten rock. This molten material can, if the tectonics are right, penetrate up through the solid outer mantle and the crust to deliver lava, which is molten rock (magma) that has reached the surface of the earth.


What is the state of matter of the Earth's upper mantle?

The Earth's upper mantle is composed of solid rock that flows through liquid rock, also known as lava.


How can lava flow from a volcano and become part of the rock cycle and eventually become a flow of lava again?

The lava is melted rock called magma when it is underground, then it is exposed and is then called lava. The volcano erupts, and it hardens into igneous rock. If the igneous rock heats up again, it is lava once more!


How does lava become an igneous rock?

lava becomes igneous rock by cooling down and hardening -ctd
