Glaciers Break Apart in a Process Known as Glacial Calving

Prepare to be enchanted as we explore the awe-inspiring wonders of our planet. From the spellbinding dance of the aurora borealis to the dramatic spectacle of a total solar eclipse, Earth's natural sights never fail to captivate. But amidst the beauty lies the raw power of nature, as hurricanes and tornadoes remind us of its relentless force. Yet, in the midst of chaos, there's also harmony – the gentle whispers of nacreous clouds and the ethereal glow of fogbows. Join us as we delve into the extraordinary, where every photo is a testament to the breathtaking marvels our world beholds. Let's embark on this journey together and marvel at the sheer magnificence of Earth's natural wonders!

As glacial ice cracks due to thawing and refreezing or its motion forward, sections of the ice can sometimes crack off at the glacier's terminus. These chunks of ice can fall extremely rapidly. The cracks can travel across the surface of the ice at speeds as high as 80 miles per hour. If the ice falls off into a body of water, it can cause large, dangerous waves to form. In addition, glacial calving is the primary source of oceanic icebergs, which can be extremely dangerous to ships.

Sinkholes: Sudden Openings of the Earth's Surface

Sinkholes are formed when the surface layer of the ground collapses into an underground tunnel or cavern as you can see in this image. These holes often fill with rainwater, which can cause a pond to form. There are different ways that sinkholes can be created, but erosion is the most common mechanism. Groundwater can erode rock beneath the surface, and this creates an opening under the surface that grows rapidly. This erosion can eventually cause a sinkhole to appear on the surface.

In other cases, sinkholes can be formed as surface water causes erosion and makes its way underground. The sinkhole is created after the surface water enters an underground tunnel or cavern.

However, sinkholes often do not open up into an underground cavern or tunnel. That's because the material leading to the collapse often blocks the tunnel. In some cases, there is actually an opening into a cavern or tunnel at the bottom of the sinkhole. Some examples of sinkholes that have an opening into a cavern are the Minye Sinkhole in Papua New Guinea and the Cedar Sink in Mammoth Cave National Park.
