Answer:
Water lowers the strength and cohesion of clay-rich regolith or soil.
Explanation:
Water can seep into the soil or clay-rich regolith and replace the air in the pore space of the soil or regolith. Water will completely surrounds all the grains of the clay-rich regolith and breaks the bonds in between the grains, that is eliminating all grain to grain contact of the regolith. When the regolith becomes saturated with water, the angle of repose is reduced to very small values and the regolith tends to loose its form.

Answer:
NaF>NH3>H2S>CO2
Explanation:
The boiling point of a substance depends on the magnitude of electronegativity difference and the type of bond between the atoms of the compound in question.
NaF is an ionic substance. Ionic substances have a high melting and boiling point due to the fact that the ionic lattice contains a large number of ions. This means that a lot of energy is usually required to overcome this ion-ion interaction therefore ionic compounds usually have high melting and boiling points.
Nitrogen is more electronegative than sulphur hence NH3 is more polar than H2S and consequently NH3 has a higher boiling point than H2S due to stronger dipole-dipole interaction.
CO2 is a nonpolar molecule hence it has the lowest boiling point. Only weak dispersion forces exist in CO2.
