Rocks can soften and weaken due to high temperatures and pressure, which cause minerals within the rock to deform and rearrange. Chemical weathering can also weaken rocks by breaking down minerals and altering rock composition. Additionally, the presence of water can promote the growth of microorganisms that contribute to rock weakening.
Technically, you develop until you're middle-aged, then your cells get weaker and causes your skin to soften and weaken, and lose hair color; thus the answer is both.
Chemicals that soften granite can weaken its structure, making it more susceptible to damage and reducing its overall durability and longevity.
Exfoliation is primarily caused by a combination of thermal expansion and contraction due to daily temperature fluctuations. The heating of rock during the day causes expansion, while cooling at night causes contraction. This continuous expansion and contraction weaken the rock, leading to exfoliation.
Oxidation in chemical weathering causes minerals containing iron to rust. This process breaks down the minerals and can weaken the rock structure, leading to eventual disintegration.

Burrowing animals can break rock through physical force, such as digging and tunneling, or through chemical processes like acid secretion. Over time, the repeated actions of burrowing can weaken and break apart rock formations.
When a piece of rock is heated up, the particles within the rock gain energy and begin to vibrate more intensely. This causes the bonds between the particles to weaken, eventually leading to the rock melting into liquid magma.
None- ALL plastics soften on heating. Even stone and rock (think volcano) will soften on heating.
Weathering processes, such as freezing and thawing, and chemical weathering from exposure to water and acids are the most likely causes for rock to crack and crumble. Over time, the expansion and contraction of these forces weaken the rock structure, leading to eventual breakage.
Rock exposed to very high temperature and pressure will soften or melt.
Weightlessness causes the bones to soften and muscle mass to reduce.
