Rocks are worn away through the process of weathering and erosion. Weathering is the breaking down of rocks into smaller pieces while erosion is what carries the rock to new places. Rocks can be worn away by water, ice, and wind. Examples of this are abrasion, ice wedging, and dissolution.
Intrusive igneous rocks are formed from magma that cools and solidifies beneath the Earth's surface. They are more resistant to weathering and erosion compared to surrounding rocks, which are often sedimentary or metamorphic in nature. Therefore, when the less resistant rocks are worn away, the intrusive igneous rocks are exposed at the surface.
The agent of mechanical weathering you are referring to is called abrasion. It occurs when rocks are physically worn down by the friction and impact of other rock particles.
Rock erosion is the process by which rocks are broken down and worn away by external factors such as wind, water, ice, and gravity. Over time, these forces can fragment rocks into smaller pieces and eventually reshape the landscape.
The process of rock being worn away by the grinding action of other rock particles is called abrasion. This can happen through the physical scraping and rubbing of rocks against each other, resulting in the wearing down of the surfaces over time.
Erosion is the process by which rocks, soil, and other materials are worn away and moved by natural forces such as wind, water, and ice. This can lead to changes in the landscape over time as rocks are broken down and sediment is carried away to new locations. Erosion plays a key role in shaping landforms and affecting ecosystems.
Erosion
"erosion"
Rocks wear away because slowly,wind/water take away tiny pieces of dust and slowly it gets worn away.
Centuries of erosion by wind have worn away the rocks.
Erosion.
Weathering and erosion.
As slate is a metamorphic rock, it can't be worn easily. I t would be harder to wear than igneous or sedimentary rocks.
Differential weathering
Intrusive igneous rocks are formed from magma that cools and solidifies beneath the Earth's surface. They are more resistant to weathering and erosion compared to surrounding rocks, which are often sedimentary or metamorphic in nature. Therefore, when the less resistant rocks are worn away, the intrusive igneous rocks are exposed at the surface.
All I know is it either could be deposit, hydraulic action, erosion, attrition, abrasion, transport, longshore drift.
The process you are describing is called erosion. Erosion occurs when rocks or soil are gradually worn away by natural forces such as water, wind, or ice.
Mechanical weathering is when rocks are worn away by physical action, ex: a river running past.
