Sand is blown against/ rubbed against the rock by sea and wind and scrapes off pieces of rock.
Wind
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.
Exfoliation is the mechanical weathering process that causes rock to flake off in layers. This occurs due to the expansion and contraction of rock surfaces, caused by temperature changes, which lead to the peeling away of outer layers of rock.
Thermal expansion causes repeated expansion and contraction within the rock. This repeated stress breaks bonds and eventually causes the rock to crack. Thermal expansion is classified as a type of physical or mechanical weathering.
Well, it's pretty simple. Mechanical weathering is the type of weathering in which rock is physically broken into smaller pieces, so a lot of things we do cause weathering. For example: mining and construction. When we mine, we slowly break down the earth's crust. Same goes for construction. Even walking across a road of gravel causes mechanical weathering! Hope I answered yourquestion! :)

Mechanical weathering by blowing sand and exposed rock is caused by abrasion, which is the process of particles in the wind rubbing against the rock surfaces. This constant rubbing and erosion over time can lead to the breakdown of the rock into smaller pieces. Additionally, the force of the wind carrying sand and small rocks can also impact the rock surfaces and contribute to the weathering process.
Wind-blown sand causes Mechanical Weathering of rocks by abrasion
If you want to draw something of mechanical weathering like me then i got the idea for you draw a rock with cracks and a concrete house with no roof at the top mechanical weathering
Mechanical weathering in the Sahara is mainly caused by the wind. Other weathering is also caused by freezing temperatures and extreme heat.
Water causes mechanical and chemical weathering.
Mechanical weathering - Disintegration - breaks down into smaller pieces, no new substance. Frost Action, Abrasion, Gravity, Organic Activity, Wetting and Drying, and Joint Sheeting are the six major causes of mechanical weathering.
What are three agents or causes of mechanical weathering?
any plant
The major cause of mechanical weathering on the moon is micrometeorites. These tiny rocks hit the moons surface and over time, change it.
