How does chemical weathering form a cave? Weak acids seep into the ground until they reach a zone soaked with water. As the ground water become more acidic, it dissolves calcite and other minerals in the rock.
Yogurt is a good food choice when you have a sore throat because it is cool and bland. The American Cancer Society explains that people with sore throats should choose bland foods like yogurt rather than acidic foods like oranges or spaghetti with tomato sauce, which may irritate the throat.
Worst foods: Avoid hot liquids and hard, scratchy foods such as potato chips, nuts, and granola. The acidic juices from raw fruits and vegetables, as well as orange juice, grape juice, and lemonade can also irritate a sore throat.
