Because they could be destroyed and recycled.
Rocks wear away because slowly,wind/water take away tiny pieces of dust and slowly it gets worn away.
When rocks wear away, it is called weathering. Weathering is the process by which rocks are broken down into smaller pieces due to exposure to environmental factors like water, wind, temperature changes, and chemical reactions.
Small rocks have a larger surface-to-volume ratio , and are therefore more quickly weathered compared to a large rock with a lower surface-to-volume ratio.
Wind can wear away rocks through a process called abrasion, where small particles carried by the wind collide with rock surfaces, gradually eroding and smoothing them over time. The force of the wind, combined with the particles it carries, can break down rocks into smaller pieces through repeated impacts, resulting in their weathering and erosion.
Limestone and marble.
Erosion can wear away all types of rocks, but it is more effective on softer rocks such as sandstone and limestone compared to harder rocks like granite and basalt. The rate of erosion depends on the rock's hardness, composition, and resistance to weathering.
Sedimentary rocks can wear away to form sediment through weathering processes such as erosion, transportation, and deposition. These rocks are formed from the accumulation and cementation of sediments over time.
Any kind. (There are more than one?)
They wear away more rapidly than marble because the metamorphic rocks are very hard and sturdy.
Yes, metamorphic rocks can wear away through erosion. This can occur when wind, water, ice, or other natural processes gradually break down the rock's surface and carry away particles or fragments of the rock. Over time, this erosion can shape the landscape and change the appearance of the metamorphic rocks.
Small rocks have a larger surface-to-volume ratio , and are therefore more quickly weathered compared to a large rock with a lower surface-to-volume ratio.
Rocks can wear away through processes like erosion, weathering, and abrasion. Over time, factors like water, wind, ice, and chemical reactions can break down rocks into smaller pieces, eventually leading to their erosion and disappearance.
