While it looks like lava, this is actually water gushing down from Yosemite's Horsetail falls. The glowing orange hue is formed when the setting sun hits it at just the right angle. Better known as the ‘Firefall’, this natural phenomenon at Yosemite National Park illuminates like a sight out of this world!

The spectacular body of ice stretches 13 miles across Mendenhall Valley! Hidden within the ice-cold exterior of the glacier are bright blue ice caves carved out by melted water that flows beneath and through the glacier. New caves are constantly formed!

It's TRUE! Mount Ijen in Java, Indonesia hosts one of the last remaining active sulfur mines in the world. The Ijen volcano is a complex group of composite volcanoes. It has attracted many tourists and scientists leaving them awestruck! The active vent at the edge of the lake also contributes to mining operations. The sulfur is originally deep red in colour but turns yellow as it cools, hence often called the ‘Devil’s Gold’.

It's Methane gas! This phenomenon happens when the decaying plants on the lake bed release methane gas, creating bubbles that become trapped within the ice, just below the surface as the lake begins to freeze. Together with the clear water, they form a beautiful sight.

It is acid rain. Through the process of chemical weathering, acid rain dissolves the calcium carbonate, a primary compound found in limestones. This creates cracks in the rock, allowing rainwater to seep downwards, further dissolving the rock layers. Over time, this results in the formation of sinkholes, underground streams, caves, and even cliffs!

It means Cotton Castle – the literal translation of the Turkish name! Its name was coined by the Turkish because of its resemblance to the cotton plantations grown in central Turkey. The temperature of waters from the hot spring ranges from 35°C to 100°C and more than 2 million people visit the fascinating hot water springs every year.
