Responses
the transformation of rocks into some other type of materials
the transformation of rocks into some other type of materials
the building up of rock that has been brought from other places
the building up of rock that has been brought from other places
the breaking of rock into smaller pieces from nonchemical processes
the breaking of rock into smaller pieces from nonchemical processes
the movement of rock from one place to another
the movement of rock from one place to another
the breaking of rock into smaller pieces from nonchemical processes
The correct answer is:
- the breaking of rock into smaller pieces from nonchemical processes
The correct answer is: "the breaking of rock into smaller pieces from nonchemical processes."
To understand physical weathering, it helps to know that weathering refers to the various processes that break down rocks and minerals on the Earth's surface. This can occur through physical or chemical means.
Physical weathering, specifically, refers to the breaking of rock into smaller pieces without any chemical changes taking place. It is also known as mechanical weathering. This type of weathering occurs primarily due to the effects of physical forces like temperature changes, pressure, ice wedging, wind erosion, and the actions of plants and animals.
To find the correct answer, it is important to read each option carefully and consider the definition of physical weathering. The first option mentions the transformation of rocks into other materials, but that is more closely related to chemical weathering. The second option refers to the building up of rock from other places, which is not related to weathering. The last option mentions the movement of rock from one place to another, which is more associated with erosion rather than weathering. Only the third option, "the breaking of rock into smaller pieces from nonchemical processes," accurately describes physical weathering.
By understanding the definition and eliminating the incorrect options, we can identify the correct answer.
