When rocks are broken down without any change to their chemical compositions it is mechanical weathering. Causes of mechanical weathering are Freezing and melting of water, Abrasion, when the rock is weather by an abrasive agent such as wind and sand, and exfoliation occurs when a rock is brought to the surface.
Mechanical weathering is simply the breakdown of rocks into smaller pieces by physical means. It does not affect a rock's chemistry and mineralogy.
Yes. Mechanical weathering can and does affect all three types of rock.
No. Mechanical weathering breaks rocks apart.
No.
Biologically, Chemically and Mechanically.
They are mechanically formed sedimentary rocks, such as Sandstone and Conglomerate.
rain, wind, heat
The rate of chemical weathering increases when a rock becomes more mechanically weathered, also called abrasion.
Rocks formed by accumulation of materials from other rocks which are cemented together. Eg: sandstones formed from sand grains, granite made up of quartz.

Mechanically
Sandstone.
Sedimentary rocks can be both chemically and mechanically weathered.

Magma. Water. Ice. Wind.
The answer to your question is: Natural acids chemically weather rocks, hope that helped....
1. Organically. 2. Mechanically. and 3. Chemically.
