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.
Stay away from acidic and citrus foods like tomatoes, oranges, grapefruit, limes and lemon. The acids found in these foods can irritate and worsen your sore throat. Instead of having citrus fruits, choose fruits that are soothing to the throat such as bananas, melons, kiwi and peaches. If you are looking to add more vitamin C into your diet, you can munch on kale or red peppers instead of irritating citrus foods.
