The only way forces in the Earth can create molten rock is by friction on a fast moving fault. The friction causes heat which can melt small amounts of the fault wall surfaces and produce a glass like melt called a "Pseudotachylite".
Note: the hot molten rocks called lava that come out of volcanoes ARE NOT produced by forces in the Earth. These are melts resulting from the heat of the planet's interior.
What else can I help you with?
The earth's surface is what on molten rock?
Molten rock on the Earth's surface is called lava.
What name is given to molten rock on the surface of the earth?
Molten rock on the surface of the Earth is called lava.
What are molten substances that appear at the surface of earth?
Molten substances that appear at the surface of the Earth include lava, which is molten rock that flows out of volcanoes during eruptions, and magma, which is molten rock beneath the Earth's surface. These molten substances can solidify into igneous rock as they cool.
How are lava and magma the same?
Lava and magma are both molten rock beneath the Earth's surface. The main difference is that magma is molten rock below the surface, while lava is molten rock that has reached the surface through volcanic eruption.
What does magma intrusion means?
Magma intrusion refers to when molten rock (magma) forces its way into existing rock formations beneath the Earth's surface. This intrusion can create new igneous rock formations, as well as potentially lead to volcanic activity if the magma reaches the surface.
Are molten rock and lava the same thing in different places?
Molten rock that has been erupted onto Earth's surface is known as lava. Molten rock within the Earth is known as magma.
When is molten rock called magma?
Molten rock is called magma when it is inside the earth. Its called lava when it reaches the Earth's surface.
Rock formed from molten rock on earth's surface?
igneous rock
What is molten material below the surface of earth called?
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.
What is molten rock deep beneath the Earth's crust called?
Molten rock deep beneath the Earth's crust is called magma.
Is the lava a rock?
Lava is molten rock on earth's surface.
What is molten rock when it is in and outside of the Earth's crust?
Igneous Rock
