Chemical a.is caused by freezing b.breaks apart rocks by physical process c.occurs when chemical reactions dissolve or change the minerals in rocks d.none above

The correct choice is C)

Occurs when chemical reactions dissolve or change the minerals in rocks

Explanation:

Chemical weathering is caused by rain water reacting with the mineral grains in rocks to form new minerals and soluble salts. Water, and many chemical compounds found in water are the main agents of chemical weathering. These reactions occur particularly when the water is slightly acidic.

C would be the answer. A way to remember is to just remember chemical weathering has to do with chemical reactions.

Newton’s universal law of gravitation states that all objects attract each other with a force -directly- proportional to the product of their masses and -inversely- proportional to the square of the distance between their centers. When considering objects on the surface of the Earth, the force is -away from directly-proportional to the product of the mass of the object and the -acceleration- due to -gravity-at the Earth’s surface. Since the Earth is -larger- than ant object under consideration, the object is drawn -toward- the Earth.
