Question

What is the alkaline component in the process of weathering that causes alkaline crystallisation?

• A. Rocks
• B. Seawater
• C. Minerals in the rocks
• D. Rainwater

Answer 1

The correct option is B Seawater

Seawater is alkaline, and when it gets into the cracks of rocks, the minerals in the rocks dissolve. This causes small holes to be formed in the rocks. When this water evaporates, only salt crystals are left behind. These crystals further stress the rocks and cause them to develop holes, leading to a honeycomb structure or alkaline crystallisation.
