How was the rock cycle made?

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.


What are the four main types of 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


Are igneous rocks the rarest rocks found on earth?

Apples are cool


What type of rocks form when molten rocks cool and solidify?

Igneous Rock


Do extrusive rocks cool quickly?

Extrusive rocks do cool quickly because either the crystals in the rock are very small or there are no crystals at all.

What kind of rock is formed when melted minerals cool and harden?

Igneous Rock.


How do igneous rocks turn into metamorphic rock?

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.


What happens to magma and lava once they cool and harden?

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.


What is rock that is melted into liquid form?

When rock is melted into liquid form, it is called magma. Magma is generated beneath the Earth's surface and can eventually cool and solidify to form igneous rocks.


How do metamorphic rocks turn into igneous rocks?

Metamorphic rocks can turn into igneous rocks through the process of melting and subsequent cooling and solidification. When metamorphic rocks are subjected to high temperatures and pressures, they can melt and form magma. If this magma makes its way to the surface and cools, it can solidify into igneous rocks.


What happens to the energy inside the rock as metamorphic rock becomes igneous rock?

Metamorphic rocks gain enegry as they are melted by magma and then lose energy as they cool into igneous rocks.


What are Igneous rocks that cool quickly beneath Earth's crust called?

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.


What rock takes the longest time to cool of?

Igneous rocks that cool under the Earth's surface. They are called intrusive rocks.


How did puritans make candles?

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.


What is it called when igneous rocks cool quickly?

obsidian


What would happen if you place melted chocolate in refrigerator?

Placing melted chocolate in the refrigerator will cause it to harden quickly. This can affect the texture and taste of the chocolate, making it less smooth and potentially changing its appearance. It is best to let melted chocolate cool at room temperature to maintain its quality.
