The reddish-brown can take a little longer to cook, but Iâve mixed the two colors together without any trouble. As a general rule, I donât keep cooked grains in the refrigerator for longer than a 3 â 4 days, and some people cut it off at 2 days.And keep in mind, quinoa freezes beautifully. To defrost, just throw it in the microwave for a minute, depending on the strength of your microwave.he reddish-brown can take a little longer to cook, but Iâve mixed the two colors together without any trouble.

In physical weathering the rocks are broken down into smaller pieces, but the chemical composition of the rock remains the same. Temperature Change Hot temperatures can give rise to thermal expansion in rocks and cool temperatures can cause rocks to contract.
Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals (clays) and soluble salts.These reactions occur particularly when the water is slightly acidic. These chemical processes need water, and occur more rapidly at higher temperature, so warm, damp climates are best.Chemical weathering (especially hydrolysis and oxidation) is the first stage in the production of soils.hese reactions occur particularly when the water is slightly acidic.
