Magma.
It is magma.
hot liquid that forms when rock melts is MAGMA
The hot liquid that forms when a rock partially or completely melts is called magma. Magma is composed of molten rock, mineral crystals, and dissolved gases. It can be found beneath the Earth's surface in the mantle and can erupt onto the surface as lava through volcanic activity.
When a sedimentary rock melts, it forms an igneous rock upon solidification. This process involves the sedimentary rock going through changes in temperature and pressure, causing it to melt and re-crystallize into an igneous rock.
When a sedimentary rock or any other rock kind melts, it becomes magma and when it sollidifies it forms an igneous rock.
metamorphic because it melts the rock and forms another
Metamorphic rock is formed.
Magma
Sedimentary rock can be changed into igneous rock by undergoing melting and then solidification.
When rock melts, it forms magma. Magma is a molten mixture of rock-forming substances, gases, and water that is found beneath the Earth's surface. If the magma reaches the surface, it can then solidify to form igneous rocks.
The rock melts, just like most other solids do when heated. Magma is to rock as water is to ice.
When rock melts at calderas, it forms magma. This magma is then forced towards the Earth's crust as lava through volcanic eruptions.
