Question

Can you please answer following questions with specific answers ;

Pleases specific answers without websites:

1/ Name one type of congruent and one type of incongruent weathering reactions?

2/ How would the water chemistry and TDS of an aquifer in a carbonate environmental compare with that of rainfall?

3/ Why are colloids able to move faster than water even through it is a larger solid?

4/ How does Bowen’s reaction series relate to weathering rates?

5/ What is the effect of covalency of bonds on the weathering rate?

Answer 1

1) In Congruent weathering reactions, the solid dissolves in water adding elements to water according to their proportions in the mineral. An example is : Solution of calcite in limestone.

In incongruent weathering reaction, only a part of the solid is consumed. An example of the incongruent weathering reaction is attack of carbondioxide-charged soilwater on mineral K-spar(KAlSi₃O₈)

**Answering only first question as per the policy, please posr the questions individually/seperately.
