Hydration as one of the processes of chemical weathering. It includes its definition, its processes, its advantages and disadvantages. CREDITS TO: JAKE PAULINO and RAPHAEL SANTIANO for making this presentation.

1. HYDRATION
Gr3: Paulino & Santiano

2. Hydration
-Hydration is a form of chemical weathering in
which the chemical bonds of the mineral are
changed as it interacts with water.
-Hydration is a type of chemical weathering where
water reacts chemically with the rock, modifying its
chemical structure.
-Hydration is a process where mineral structure of
the rock forms a weak bond with H20 which causes
the mineral grains to expand, creating stress which
causes the disintegration of the rock. Hydration
often produces a new mineral compound that is
larger than the original compound. The increased
size expanse the rock and can lead to decay.

3. Example: Anhydrite (CaSO₄) --> Gypsum (CaSO4·2H2O)

4. Process
-water molecules
hydrate ions causing the
mineral to expand. the
expansion causes the
mineral to break,
allowing the new
compund to form.

5. potential benefits of
enhanced rocks
Advantages
some minerals in rock may
decompose

6. Summary
Hydration is the chemical
reaction of water and
minerals, modifying the
structures of minerals,
causing expansion, which in
terms, leads to weathering.
