Hello friend
___________________________
This type of weathering is mainly seen on the rocky coast.When waves break at the cost their water droplets hit the sea Cliffs.In this saline water, the soluble materials in the rocks get dissolved and small holes are formed in the rocks .
This is the effect of solution.Through these holes saline water enters the rock.After evaporation of water the salts remains in the rocks itself .
When they undergo crystallisation crystals grows and occupy more space.These creates tension in the rocks.
The holes get enlarged.This gives the cliff an appearance of honeycomb and hence this type of weathering is called honeycomb weathering and the type are called Salt Weathering.
Thanks....

Weathering is the breaking down of rocks, soil, and minerals as well as wood and artificial materials through contact with the Earth's atmosphere, water, and biological organisms. Weathering occurs in situ (on site), that is, in the same place, with little or no movement, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.
Two important classifications of weathering processes exist – physical and chemical weathering; each sometimes involves a biological component. Mechanical or physical weathering involves the breakdown of rocks and soils through direct contact with atmospheric conditions, such as heat, water, ice and pressure. The second classification, chemical weathering, involves the direct effect of atmospheric chemicals or biologically produced chemicals also known as biological weathering in the breakdown of rocks, soils and minerals.[1] While physical weathering is accentuated in very cold or very dry environments, chemical reactions are most intense where the climate is wet and hot. However, both types of weathering occur together, and each tends to accelerate the other. For example, physical abrasion (rubbing together) decreases the size of particles and therefore increases their surface area, making them more susceptible to rapid chemical reactions. The various agents act in concert to convert primary minerals (feldspars and micas) to secondary minerals (clays and carbonates) and release plant nutrient elements in soluble forms.
