Why do angular aggregates better suit freeze thaw than rounded aggregates?

-Because angular aggregates have lower absorption. Rounded aggregates have larger critical sizes which can have no impact on freeze thaw.

Is this true? If not, why?

Answer #1

The angular shapes have larger surface area as compared to the rounded ones with the same mass, so their area of exposure is higher. So it is wrong to say they angular particles have lowwr absorption. On the other hand it will be higher. Rounded sizes has smallest sizes.

On the other hand angular particles has the advantage of better interlocking, and thus perhaps better resistance against any stresses. When they are well graded, they will have less water permeability and higher strength.

The equilibrium theory of island biogeography states that larger islands will have a lower  rate than small islands because larger islands can support larger populations. Islands that are closer to the mainland will have a higher  rate than ones further away because individuals are more likely to successfully travel to close islands, and a lower extinction rate because the ____________ effect will be higher, preventing declining island populations from going extinct through the arrival of new immigrants.
