This new rock-breaking drilling technology applies a mechanical amplitude to the rock to generate a mechanical vibration frequency (up to 18 kHz) that is equal or close to the natural frequency of the rock (generally in the range of 20–40 kHz), causing the rock to resonate and fragment (Zhou et al., 2019). It has advantages, such as high ...

Rocks and pebbles carried by the river scrape and rub against the channel, eroding it. Attrition: Rocks and stones that the river carries knock against each other, breaking into smaller, rounder, and smoother fragments. It's like a natural rock tumbler, where rough edges get smoothed over time.

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary Rocks Sedimentary rocks are formed from pieces of other existing rock or organic …

Weathering Versus Erosion. Weathering and erosion sort of sound like the same thing, but geologists make a fairly simple distinction. With weathering, we are merely speaking of the in situ breakdown of rock material without transport. In other words, weathering involves rocks breaking apart along fractures but not moving from the site of disaggregation.

Chemical and mechanical weathering work hand-in-hand via a fundamental concept called surface-area-to-volume ratio. Chemical weathering only occurs on rock surfaces because water and reactants cannot penetrate the solid rock. Mechanical weathering penetrates the bedrock, breaking large rocks into smaller pieces and creating new rock surfaces.
