Cracks in buildings due to atmospheric drying of moisture in building materials cause:

Explanation:

Shrinkage cracks

• These cracks are caused by the atmospheric drying of moisture in building materials, particularly concrete and plaster.

• As the material dries and loses moisture, it contracts, leading to cracks, which are typically shallow and non-structural.

Additional Information

1. Structural cracks

   • Caused by issues like excessive loading, foundation movement, or design defects.

   • These cracks affect the stability and strength of the structure.

2. Shrinkage cracks

   • Result from moisture loss during the drying of materials, leading to contraction and cracking.

3. Thermal cracks

   • Caused by temperature fluctuations that cause expansion and contraction in materials.

   • Not specifically related to moisture drying but more to thermal stress.

4. Settlement cracks

   • Occur when the foundation settles unevenly, causing movement in the structure.

   • These cracks are typically deeper and structural in nature.
