Question 6
Karst topography is a landscape or landform created when nearby groundwater or surface water dissolves rocks.
Examples of karst topography include caves and sinkholes, as shown in the images.
Based on your experimental results, what can you conclude about the type of rocks that once existed in these
locations and the acidity of the nearby groundwater?

The type of rocks that once existed in these locations are limestone and dolomite whereas the pH of the nearby groundwater is slightly acidic which is responsible for the formation of caves. Caves are formed by the dissolution of limestone due to acid rain.

Acid rain

Rainwater reacts with carbon dioxide from the air and percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone which become turn to form caves so we can conclude that Limestone and dolomite are the rocks present in the locations which leads to the formation of caves.

Answer:

The rocks present in the locations that lead to the formation of caves are limestone and dolomite.

The rocks that once existed in these locations are limestone and dolomite, and the pH of the nearby groundwater is slightly acidic, which is responsible for cave formation. Caves are formed as a result of the dissolution of limestone caused by acid rain.

Rainwater reacts with carbon dioxide from the atmosphere as it percolates through the soil, forming a weak acid. This gradually dissolves the limestone, which then forms caves, so we can conclude that limestone and dolomite are the rocks present in the locations that lead to cave formation.
