Scientists refer to the early Earth, when its outer surface was completely molten, as the "Hadean" eon. This period, which lasted from about 4.6 to 4 billion years ago, is named after Hades, the Greek god of the underworld, reflecting the harsh and hellish conditions of the planet during this time. The Hadean eon is characterized by intense volcanic activity, frequent impacts from celestial bodies, and a lack of stable crust.
The molten material that reaches earth's surface is lava :)
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.
Molten rock on the surface of the Earth is called lava.
Molten rocks under the Earth's surface are called magma. When magma reaches the Earth's surface, it is then called lava.
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.

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.

True, lava is molten rock that has reached the Earth's surface, while magma is molten rock beneath the Earth's surface.
The earth was in molten state for approximately 0.8-1 billion years.
Molten rock from under the surface (called 'magma') that reaches the Earth's surface and flows out is is called 'lava'.
Early in its history Earth was either completely or almost completely molten. The liquid state allowed the denser materials to sink deeper into Earth's interior while less dense materials floated closer to the surface.
Molten rock that is contained below the earth's surface is known as magma. Once it break the surface of the earth, as in a volcanic eruption, it is called lava.
