Status Updates From Natural Wonders of the World

We’ll see how long it takes me to read this coffee table book. It has beautiful pictures. And is awe inspiring

The Perot Moreno Glacier acts as a dam, separating two lakes from each other.

There are rocks that seem to move on their own in the Mojave Desert, just like that episode in Spongebob. The rocks move when thin ice flows get blown by the wind.

In the winter at Lake Abraham, stack of cotton-like bubbles are trapped under the ice. These bubbles form from the methane gas released as bacteria decompose at the bottom of the lake

- Glaciers move downhill due to pressure from their own weight

- The front of a glacier (where it is moving to) is the snout. The back of the glacier (where it is moving from) is the terminal

- Moraines are rock fragments that are being carried along by a glacier, revealing dark bands

- The Appalachians started rising 480 million years ago (older than bones) They were once probably as tall as the Himalayas, but have been eroded over millions of years

- The Great Lakes freshwater came from the melting of the giant ice sheet at the end of the last ice age.

- Calderas form when a volcano erupts and leaves part of its magma chamber empty, allowing the top layers to collapse in, forming a depression.
