What is a metamorphic rock facts for kids?
Metamorphic rocks are formed when other rocks are affected by great temperatures and pressures. They do not melt, but the chemicals they contain may change their forms, or crystal shapes. Marble and slate are two examples of metamorphic rocks. The name metamorphic comes from Greek words meaning “change of shape.”

Fun Facts About Metamorphic Rocks for Kids
- Many metamorphic rocks are made of layers that can be split apart.
- Magma under the earth sometimes heats rocks, causing them to change.
- Marble is a type of metaphoric rock made from limestone or chalk and is usually found in the mountains.
What are 4 facts about metamorphic rocks?
The word metamorphic literally means “changed form”. Slate, a metamorphic rock, can form from shale, clay or mudstone. The Taj Mahal in India is made entirely of different types of marble, a metamorphic rock. Serpentine is a type of metamorphic rock that originates as the igneous rock periodite.
What is metamorphic rock in simple words?
A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. Its name is from ‘morph’ (meaning form), and ‘meta’ (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change.
Did you know facts about metamorphic rocks?
Metamorphic Rock Facts
- Metamorphic rocks have been changed over time by extreme pressure and heat.
- Metamorphic rocks can be formed by pressure deep under the Earth’s surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
What things are made from metamorphic rock?
Quartzite and marble are the most commonly used metamorphic rocks. They are frequently chosen for building materials and artwork. Marble is used for statues and decorative items like vases (Figure 4.15). Ground up marble is also a component of toothpaste, plastics, and paper.

What is metamorphic rock used for?
Why is it called metamorphic rock?
The word metamorphism is taken from the Greek for “change of form”; metamorphic rocks are derived from igneous or sedimentary rocks that have altered their form (recrystallized) as a result of changes in their physical environment.
What’s metamorphic rocks made of?
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
What are some interesting facts about rocks?
Interesting Facts about Rocks The word “igneous” comes from the Latin word “ignis” which means “of fire.”. Ores are rocks that include minerals that have important elements such as metals like gold and silver. Sedimentary rocks form layers at the bottoms of oceans and lakes.
How to know about metamorphic rocks?
Hold the rock to the light and see if it has a shine or shimmer. Metamorphic rocks tend to have more luster than igneous or sedimentary rock.
How is metamorphic rock formed for kids?
How are Metamorphic Rocks Formed Video for Kids. Metamorphic rocks are formed from other rocks when they are changed because of heat and pressure. These changes occur in the process of metamorphism. This rock is formed underground through when molecular structure of a rock is changed due to heat, pressure and chemical reactions.
What type of rock can form a metamorphic rock?
Igneous – they form from the cooling of magma deep inside the earth. They often have large crystals (you can see them with the naked eye).
