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.
What else can I help you with?
What are three ways sedimentary rocks can form?
Biologically, Chemically and Mechanically.
What are 3 processes that mechanically weather rocks?
Three processes that mechanically weather rocks are frost wedging (freeze-thaw cycles), exfoliation (physical weathering due to pressure release), and abrasion (erosion caused by frictional forces).
How water can breakdown rocks mechanically explain?
Water can breakdown rocks mechanically through a process called hydraulic action, where water enters cracks and crevices in rocks. When this water freezes and expands, it exerts pressure on the rock, causing it to crack. Additionally, water can carry sediment and debris that effectively wear down rock surfaces through abrasion.
Does the rate of chemical weathering increase or stay the same when the rocks becomes more mechanically weathered?
The rate of chemical weathering increases when a rock becomes more mechanically weathered, also called abrasion.
What are rock groups that are classified as clastic sedimentary rocks?
Some examples of clastic sedimentary rocks include sandstone, conglomerate, shale, and breccia. These rocks are formed from the accumulation of fragments of pre-existing rocks and minerals, which are then compacted and cemented together over time.
What process carries away soil and weatherd rocks?
erosion
Does wind weather rocks mechanically or chemically?
Mechanically
What are mechanically formed rocks?

Are sedimentary rocks chemically weathered?
Sedimentary rocks can be both chemically and mechanically weathered.
What is the type of weathering that mechanically breaks down rocks?
