Yes, rock can bend without melting under certain conditions, primarily due to the effects of pressure and temperature over long periods. This process, known as ductile deformation, occurs in the Earth's crust where rocks can flow and change shape without reaching their melting point. This phenomenon is commonly observed in tectonic settings, such as during the formation of mountains or in fault zones.

No, a fault is not a bend in layers of rock; rather, it is a fracture or zone of weakness along which movement has occurred. In contrast, a bend in layers of rock is typically referred to as a fold. Faults result from tectonic forces causing rocks to break and shift, while folds occur due to compressional forces that bend the rock layers without breaking them.
A bend in a crustal rock is a deformation where the rock has been subjected to stress, causing it to bend without breaking. This bending can occur due to tectonic forces such as compression or extension, resulting in curved layers or shapes in the rock. Bends in crustal rocks are commonly seen in mountain ranges where tectonic forces have been active.
Rocks can bend or fold without melting primarily due to temperature and pressure conditions, which influence their ductility. At significant depths within the Earth's crust, high temperatures and pressures allow rocks to deform plastically rather than fracturing. Additionally, the mineral composition and water content of the rocks play a crucial role; certain minerals are more malleable, and the presence of water can reduce friction and facilitate bending. These factors together enable rocks to undergo deformation without reaching their melting point.
Metamorphic rock forms due to high heat and pressure without melting. This process alters the mineral composition and structure of the original rock (either igneous, sedimentary, or another metamorphic rock) through recrystallization. Common examples of metamorphic rocks include schist, gneiss, and marble. The transformation occurs while remaining solid, distinguishing metamorphic rocks from those that form from melting or cooling of magma or lava.

Metamorphic rocks form when existing rocks are subjected to high heat and pressure without melting. This process causes the minerals and texture of the rock to change, resulting in a new type of rock. Examples of metamorphic rocks include marble, slate, and gneiss.
No, metamorphism usually does not involve melting. Instead, it involves changes in temperature and pressure that alter the mineral composition and texture of rocks without causing them to melt completely.
It is called folding when rocks bend without breaking because of plate movement.

Metamorphic rock usually forms when a rock is altered under heat and pressure without melting. Some rocks may be metamorphosed by contact with hot water,
Melting causes an igneous rock to form into lava/magma.

The melting of metamorphic or igneous rock forms magma.
