⚡ How Was Son Doong Cave Formed?

1️⃣ Limestone Formation – Formed over 2–5 million years from limestone dissolution by underground rivers.

2️⃣ Karst Topography – The area’s limestone mountains and sinkholes contributed to massive cave development.

3️⃣ River Erosion – Underground rivers carved huge caverns and chambers over time.

4️⃣ Collapse of Roof Sections – Created giant openings and light-filled chambers, allowing vegetation to grow inside.
