Detailed explanation-1: -Physical weathering involves the breakdown of rocks into smaller fragments through processes such as expansion and contraction, mainly due to temperature changes. Two types of physical breakdown are freeze-thaw weathering and thermal fracturing. Pressure release can also cause weathering without temperature change.
Detailed explanation-2: -Weathering is the breaking down or dissolving of rocks and minerals on Earths surface. Once a rock has been broken down, a process called erosion transports the bits of rock and minerals away. Water, acids, salt, plants, animals, and changes in temperature are all agents of weathering and erosion.
Detailed explanation-3: -(b) Physical Weathering is when rocks are broken apart by mechanical processes such as rock fracturing, freezing and thawing, or breakage during transport by rivers or glaciers.
Detailed explanation-4: -The correct option is A Weathering. Breaking down of rocks by the action wind and climate is called weathering.
Detailed explanation-5: -Sun, rain, frost, and wind are breaking down even the most solid of the rocks into smaller bits before they are taken away. This process is termed as weathering.
