Question

(a) Explain how huge difference in temperature contributes to the weathering process​

Answer 1

Answer:

Heya your answer goes like this

A chunk of solid rock in the hand--let alone a snowy peak on the horizon--might seem permanent and unchanging, an indestructible bone of Earth. Yet, like water or organic matter, rocks are constantly transformed.

Temperature is an essential part of rock creation, modification, destruction and ultimate rebirth. And, weathering is the first step in the breakdown of rock into smaller fragments. This process is critical to the the formation of landscapes and many other geological processes.

Weathering

Weathering refers to a group of processes that pulverize rocks into smaller fragments. Think of mechanical weathering as rock-breaking. It is the result of physical forces such as the freeze-thaw cycle of water. Water trickles into joints and fractures in solid rock, freezes and expands. The expansion puts pressure on the surrounding rock and gradually widens the cracks. As water and ice penetrate more deeply, pressure eventually forces apart whole slabs of rock. Over time, frost action can reduce rock to silt-sized particles.

Hope it helps!

Answer 2

$\huge{\fbox{\fbox{\bigstar{\mathfrak{\red{Answer}}}}}}$

Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens.♥️
