Which materials are formed from molten rock?
Igneous rock is formed from molten rock. When igneous rock breaks down, it forms lava and it also forms volcano erupting pumice.
Which would have larger crystals an igneous rock formed from magma below the surface or igneous rock cooled from lava on the surface?
Crystals are generally formed when magma or molten rock cools and solidifies. Rapid cooling of the molten rock generally results in the formation of small crystals, like when magma reaches the surface. However, if they cool down slowly, then large crystals are formed. Keeping heat applied allows more growth on the crystal over time. In that logic, larger crystals grow underground.
What type of atmosphere is present when earth is formed?
The atmosphere of Earth has changed since its formation. When the Earth formed 4.6 billion years ago, it was a molten ball of rock with an atmosphere of hydrogen and helium. This atmosphere was blown away by the solar winds because there was no magnetic field to protect the Earth. After the Earth cooled, volcanoes released gases such as water vapour, ammonia and carbon dioxide. The ammonia was broken down into nitrogen and hydrogen by sunlight. Eventually, the evolution of cyanobacteria released oxygen into the atmosphere, which began to have a similar composition to the modern atmosphere.
When molten lava hardens and turns to rock?
When it cools down.
Are volcanoes made of rock?
A volcano is a part of the earth where there is so much heat underground that the rocks actually melt and are forced to the surface. Volcanoes are formed of the rock that solidifies as that molten rock cools down and hardens.

How has earth evolved over the last 4.5 billion years ago?
No. Not much known during the Big Bang, but the big bang was 4.5 billion years ago, and it is today. Earth was formed once the big bang cooled down, and the big bang formed petrol in the ground because everything has been molten and formed petrol and got buried by the radiation when the bang cooled down and formed Earth.
How were the dark spots on the moon formed?
i think when the moon cooled down.

What happens to atoms when cooled?
as the atom cools down it comes back in its orignal shape .it will be in its contracting form
Where rocks came from?
Molten magma cooled to become igneous rocks. Igneous rock eroded to become sediment which washed down into lakes and seas, became compacted and formed sedimentary rocks. Tectonic plate movements created mountain ranges which buried igneous and sedimentary rocks deeply to form metamorphic rocks.
How do golds from mining turn to jewelry?
Your Mom. The Gold is first melted then it is cooled down for 3 weeks after being formed into special shapes
Could you use molten in a sentence?
Molten: The boy poured molten steel down his own throat. :)
How do igneous rocks form?
Igneous rock forms from the cooling of molten material called magma or lava.
