Question

Assertion (A): A Karst topography is characterized by the formation of stalactites and stalagmites.
Reason (R): Solution is a dominant process in the development of land forms in Karst Region

• A. Both A and R are true and R is the correct explanation of A
• B. Both A and R are true but R is not the correct explanation of A
• C. A is true but R is false
• D. A is false but R is true

Answer 1

Answer:

B. Both A and R are true but R is not the correct explanation of A

Karst topography

• Karst topography, is a distinctive landscape characterized by unique landforms and geological features.
• Karst landscapes develop in areas with soluble bedrock, primarily limestone, dolomite, or gypsum, and are shaped by the dissolution of these rocks by natural processes

Solution

• Solution is a dominant geological process in the development of landforms in karst regions.
• Solution processes involve the chemical dissolution of soluble rocks, such as limestone, dolomite, or gypsum, by acidic groundwater.
• Over time, as water percolates through the rock, it gradually dissolves it, creating a variety of unique and distinctive landforms.

Here while both statements are true, they are not directly related or explaining each other.

The formation of stalactites and stalagmites is a specific result of solution processes in karst regions, but the reason is not providing a direct explanation for this particular formation.
