1).What is mechanical weathering?\
2.)How do water, ice, wind, and organisms cause mechanical weathering?
ASAP

mechanical weathering  --is the process of breaking big rocks into little ones

when rivers or ocean waves cause rocks to collide and scrape against each other. Ice can cause mechanical weathering when glaciers cause rocks to scrape against each other. Ice can also cause mechanical weathering when water gets in cracks in rocks, and then freezes and expands.

Explanation:

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
