Songhua River

The main stem of the river and its myriad channels appear deep blue, winding from bottom left toward center right. To the west of the river, shallow lakes appear electric blue. The surrounding landscape reveals the Manchurian Plain in shades of brown, crossed by pale lines (roads) and spots (villages and towns). 

The area in this picture is about 32 kilometers by 41 kilometers, and is centered near 45.4 degrees North latitude, 126.9 degrees East longitude.

The extreme flatness of the Northeastern China Manchurian Plain has caused the Songhua River to meander widely over time. The result of the meandering is that the river is surrounded by a wide plain filled with swirls and curves, showing paths the river once took. The plain includes classic features of meandering rivers, such as ox-bow lakes—semi-circular lakes formed when a meander is cut off from the main channel by river-deposited sediment. Meandering rivers shift their positions across the valley bottom by depositing sediment on the inside of bends while simultaneously eroding the outer banks of the meander bends.

Find cities with similar climate

This map has been created using The Global environmental stratification. The Global environmental stratification (GEnS), based on statistical clustering of bioclimate data (WorldClim). GEnS, consists of 125 strata, which have been aggregated into 18 global environmental zones (labeled A to R) based on the dendrogram.

The Appalachian Mountains, the Scottish Highlands, and the Atlas Mounts in Africa were the same mountain range

The Central Pangean Mountains was a prominent mountain ridge in the central part of the supercontinent Pangaea that extends across the continent from northeast to southwest through the Carboniferous , Permian Triassic periods. The mountains were formed due to a collision within the supercontinents Gondwana and Laurussia during the creation of Pangaea. It was comparable to the present Himalayas at its highest peak during the start of the Permian period. It isn’t easy to assume now that once upon a time that the Scottish Highlands, The Appalachian Mountains, the Ouachita Mountain Range, and the Atlas Mountains in northwestern Africa are the same mountains , once connected as the Central Pangean Mountains.

Human Emotions Visualized

Despite significant diversity in the culture around the globe, humanity's DNA is 99.9 percent alike. There are some characteristics more primary and typical to the human experience than our emotions. Of course, the large spectrum of emotions we can feel can be challenging to verbalize. That's where this splendid visualization by the Junto Institute comes in. This visualization is the newest in an ongoing attempt to categorize the full range of emotions logically. Our knowledge has come a long route since William James suggested 4 primary emotions: fear, grief, love, and rage. These kernel emotions yet form much of the basis for current frameworks. The Junto Institute's visualization above classifies 6 basic emotions: fear, anger, sadness, surprise, joy, love More nuanced descriptions begin from these 6 primary emotions, such as jealousy as a subset of anger and awe-struck as a subset of surprise. As a result, there are 102 second-and third-order emotions placed on this emo
