Mechanical weathering can change the size of a rock by breaking it into smaller pieces through processes like frost wedging, root wedging, and abrasion. The physical forces acting on the rock cause it to fragment into smaller pieces without changing its chemical composition.

What the a force that acts on a rock to change it?
The force that acts on a rock to change it is usually weathering and erosion. Weathering breaks down the rock into smaller pieces, while erosion transports these pieces to a new location, changing the shape and size of the original rock.
Which type of weathering occurs when only the size of a rock is changed?
Mechanical weathering, specifically the process known as abrasion, occurs when only the size of a rock is changed. This process involves the physical breakdown of rocks into smaller pieces through the grinding and rubbing action of moving sediment or other rocks.
Which type of weathering only affects the size of a sample?
Mechanical weathering, also known as physical weathering, only affects the size and shape of the rock without changing its mineral composition. This can be caused by processes such as freeze-thaw cycles, root wedging, and salt crystal growth.
Are all wathered rock fragments all the same size why or why not?
No, weathered rock fragments can vary in size depending on the type of weathering that occurs. Mechanical weathering can break rocks down into different sizes, forming a mixture of small and large fragments. Chemical weathering can also cause rocks to disintegrate into varying sizes based on the mineral composition and the intensity of the weathering process.
What always changes in a rock during physical weathering?
During physical weathering, the size and shape of the rock fragments can change as they are broken down and transported by natural processes like wind, water, or ice. The texture and surface features of the rock may also be altered as a result of abrasion and other physical actions that occur during weathering.
What are two ways mechanical weathering change rocks?
Two forms of mechanical weathering are frost heaving and plant root wedging. All forms of mechanical weathering result in the breakage of rock into smaller size particles.
What type of weathering occurs when only the size of the rock change?
physical weathering
Which typeof weathering would change the size of a rock but not its chemical composition?
Mechanical weathering, like wind, water, and other forms of erosion. Now, rain and some rivers contain diluted rocks and can change rocks.
What are two ways that mechanical weathering changes rocks?
Ice live
Animal burrows dug in rock that let in water and air chemical or mechanical?
Plant growth is both a chemical and mechanical process. The roots secrete mild acids that dissolve minerals in rocks, and the plant's roots and stems can increase in size and force rocks apart inside cracks and crevices.

Can physical weathering make a rock bigger?
Physical weathering is mechanical action which typically erodes rock faces. This invariably results in a smaller rock. Chemical weathering involves water absorption or other reactions. Mechanical heating and freezing can crack and fissure the rock, slightly increasing its size. In general, physical weathering is an abrading process, whether via water born sediment wearing away the rock, or wind blown particles sand blasting the rock, and these actions make reduce the rock's size.

Compare and contrast mechanical weathering and chemical weathering?
Mechanical weathering physically breaks down rocks into smaller pieces through processes like frost wedging and root growth. Chemical weathering alters the composition of rocks through chemical reactions, such as oxidation or hydration, which changes the minerals present. Both processes work together to break down rocks and transform Earth's surface.
