The correct answer is: The breaking of rock into smaller pieces from non-chemical processes.
To determine the correct answer, we can break down the question into smaller parts and analyze each option:
Option 1: "The breaking of rock into smaller pieces from non-chemical processes."
This option accurately describes physical weathering as it refers to the process of rocks being broken down into smaller pieces due to mechanical forces such as temperature changes, pressure, or abrasion.
Option 2: "The transformation of rocks into some other type of materials."
This option describes a different process called chemical weathering, where rocks are broken down through chemical reactions that transform them into new substances. It is not the correct description for physical weathering.
Option 3: "The building up of rock that has been brought from other places."
This option describes depositional processes, which involve the accumulation and building up of sediments or rocks that have been transported from one place to another. It is not the correct description for physical weathering.
Option 4: "The movement of rock from one place to another."
This option describes the process of erosion, where rock materials are transported and moved from their original location to a different place. It is not the correct description for physical weathering.
Therefore, the correct answer is the first option: "the breaking of rock into smaller pieces from non-chemical processes."
