temperature is an essential part of rock formation, modifications and destruction and ultimate rebirth.a nd weathering is the first step in breakdown of rock into smaller fragments.T his process critical to the formation of landscapes and many other geographical processes....
In Earth’s mantle, lava cools as it rises, forming solid rocks in our planet’s crust. The lava forms when tectonic plates – the fractured slabs of crust – are shoved back down under each other into the mantle and melt. In this way, a balanced cycle of meting, rock formation and remelting continues through the ages,At depth, slow-cooling lava forms coarse-grained, volcanic rock such as granite. Finer-grained rock such as basalt occurs when lava erupts or oozes to the surface and cools quickly. In metamorphic rocks, intense heat or pressure change the minerals of volcanic or sedimentary rocks. Metamorphism can occur at depth or at Earth’s surface, whenever a sheet of lava flows over and bakes other rocks. Bhai aab nhi Aata brain fail ho gya maff kr dena

it is very tough
answer
what u mean??
it's still not exposing how it helps in weathering
u should write of exfoliation Here
??

hey mate here is ur ans
the change in temperature causes alternate contraction and expansion of the layers
this causes peeling off the rock (exfoliation)
thus making the rock weak and prone to weathering
