Molten rock is magma. It is called lava once it has cooled and hardened.
hen rocks are pushed deep under the Earth's surface, they may melt into magma. If the conditions no longer exist for the magma to stay in its liquid state, it will cool and solidify into an igneous rock. A rock that cools within the Earth is called intrusive or plutonic and will cool very slowly, producing a coarse-grained texture. As a result of volcanic activity, magma (which is called lava when it reaches Earth's surface) may cool very rapidly while being on Earth's surface exposed to the atmosphere and are called extrusive or volcanic rocks. These rocks are fine-grained and sometimes cool so rapidly that no crystals can form and result in a natural glass, such as obsidian. Any of the three main types of rocks (igneous, sedimentary, and metamorphic rocks) can melt into magma and cool into igneous rocks.
Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks.Perhaps this site would be helpful to further answer your question.http://www.fi.edu/fellows/fellow1/oct98/create/igneous.htm
Apples are cool
Igneous Rock
Extrusive rocks do cool quickly because either the crystals in the rock are very small or there are no crystals at all.
Yes, melted chocolate chips will harden when left to cool.
igneous rocks
Igneous rock is formed when melted minerals cool and harden. This process can happen either beneath the Earth's surface (intrusive igneous rock) or on the surface (extrusive igneous rock). Examples of igneous rocks include granite, basalt, and obsidian.
metamorphic rocks are heated and pressured so soon they are being melted turning into magma. But volcanic activity can also release lava which would cool and harden either in crack inside the volcano or on earths surface.
Once magma and lava cool and harden, they solidify to form igneous rocks. The texture and composition of the rocks depend on the cooling rate and mineral content. Over time, these rocks can be uplifted, eroded, and transformed in the Earth's crust through various geological processes.

Igneous rocks that cool quickly beneath earth's crust are known as intrusive rocks. These rocks will form from magma which will cool and solidify quickly.
Metamorphic rocks gain enegry as they are melted by magma and then lose energy as they cool into igneous rocks.

Puritans made candles by dipping a wick repeatedly into melted tallow or beeswax, allowing each layer to cool and harden to build up the candle. The wick would absorb the melted wax, creating a solid candle as it dried.
