The Earth Story

@earthstory / earthstory.tumblr.com

This is the blog homepage of the Facebook group "The Earth Story" (Click here to visit our Facebook group). “The Earth Story” are group of volunteers with backgrounds throughout the Earth Sciences. We cover all Earth sciences - oceanography, climatology, geology, geophysics and much, much more. Our articles combine the latest research, stunning photography, and basic knowledge of geosciences, and are written for everyone!
We hope you find us to be a unique home for learning about the Earth sciences, and we hope you enjoy!

Sea Stacks in Oregon Sea stacks are stranded pillars of rock, isolated from their coastline brethren. Headlands that jut outwards over an open body of water leave themselves prone to erosion. Over long periods of time water and wind wear down the land formation creating a cave, which will slowly extend upwards to form an arch. Eventually the top of the arch erodes and collapses leaving an isolated pillar (sea stack.) Sea stacks are usually composed of rocks that are more resistant to erosion. The rocks in the picture above are comprised of sedimentary sandstone, chert layers derived from silica-rich sedimentary rocks, such as sandstone, blocks of greenstone and blueschist rocks formed from metamorphism of igneous rocks. http://bit.ly/1IlWrfa http://bit.ly/1Cf8tyS KKS Photo Courtesy of Marli Miller

This is really fun. Original caption:

Inspired by the viral success of their Only Slightly Exaggerated campaign in 2018, Travel Oregon partnered again with Wieden + Kennedy and Psyop to tell part two of this magical tale.
With the creative learnings from the first film, directors Todd & Kylie with animation partners Sun Creature pushed up the dial on the fantasy this round. With more breathtaking vistas and fantastical creatures, hovering just in the liminal space between imagination and reality, Travel Oregon is at once a loving homage to Oregon and a celebration of that exhilarating feeling all travelers experience of the sublime places they carry back in their memories and hearts.
To dive deeper into the ideas driving this campaign:

Apostles

Along the southern coast of Victoria, Australia, sits Port Campbell National Park, home of the fascinating sea stack formations known as the apostles (after some collapses, there are currently 8 of them).

The rocks are limestones of the Port Campbell limestone, a fairly soft and layered limestone that is 15 to 20 million years old – deposited at a time when sea level was slightly higher than now and the area was submerged.

As sea level has migrated up and down over the last few hundred thousand years, it occasionally paused at certain levels, leading to rapid scouring and erosion of the exposed layers. 15,000 years ago these limestones were far above sea level and eroding slowly. When the last glaciation ended, sea level rose and reached a level where the waves began pounding these layers, breaking them apart into the shapes found today over a fairly short time geologically.
