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?
lava in the mantle
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.
When rock in earth's mantle melt what does it become?
Melted rock in the Earth's mantle is called magma.
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 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.

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 does a rock become when it melts?
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
When a rock melts what substance does it become?
Lava.
How lava is made?
Most of Earth's interior is composed of a layer called the mantle. The mantle is so hot that the rocks in it would melt if exposed at the surface, but it is kept in a semisolid state by immense pressure. Under some circumstances some of the upper part of the mantle can melt to make magma. If this magma reaches the surface it is called lava. Magma can form in the mantle in three ways:Tectonic plate pull apart, causing the crust to become thin, which reduces pressure on the mantle and allows rock to melt.A slab of oceanic crust slides into the mantle, taking some water with it. The water alters the chemistry of the mantle rock and allows some of it to melt.Extra hot rock in the mantle rises to just below the crust and begins to melt.
