5. Students in Mr. Stoval's class were studying weathering and erosion. One group of students placed some limestone chips in a beaker. Next they poured in 50 ml of water to which they added 5 ml dilute HCl. After 48 hours, the limestone chips had almost disappeared and the water was cloudy. This simple experiment is an example of what process on Earth?

Water physically erodes limestone and it is carried away by moving groundwater.
Acid rain falls over limestone rock and washes particles away. This is the result of the kinetic energy of the moving water and it is a physical process.
Acidic groundwater or precipitation chemically reacts with limestone resulting in Karst features.
Acid rain falls on limestone rock and physically dissolves the particles in the rock. This is similar to dissolving salt in water. It occurs in places where evaporite form.

Answer 1

The correct answer is:

Acidic groundwater or precipitation chemically reacts with limestone resulting in Karst features.
