(i) evaporation;
? High temperatures in arid and semi-arid areas cause evaporation of water in
lakes/seas. This leads to high concentration of mineral salts in the water.
Continued evaporation causes further recrystallization of the salts which may
thereafter be attracted as minerals such as soda ash and common
salt/deposition of salts near the surface
(ii) vulcanicity;
? When molten magma intrudes into rock joints minerals contained in the
magma embedded in the joints called veins. Such minerals as tin and copper
occur in this form/Hot springs/geysers. Fumaroles bring minerals to the
earth's surface
(iii) metamorphism
? High pressure and heat cause recrystallization and hardening of certain rocks
causing them to change their nature to and become minerals such as
diamond.
