The three layers of Earth are core, mantle and crust. Each of these layers has distinct characteristics. Understand their properties, composition and more.
We assume an ideally uniform inner core boundary so that the PKiKP phase can be used as a reference, and the relative travel time/amplitude variation is ascribed to the interior IC structures. However, we acknowledge that the method does not account for structures like IC mushy zones that wer...
The plant life that had dominated the land and filled the shallow seas with plant matter, ceased to grow and eventually the plant matter became compact over layers of sediment for millions of years. Combined with the pressure from the weight of the sediment and heat from below, the plant mat...
Diagram showing the sun at the center of our solar system (not to scale). (Image credit: NASA/JPL-Caltech) Internal structure and atmosphere of the sun The sun and the atmosphere of the sun are divided into several zones and layers. The solar interior, from the inside out, is made up...
Being at the surface is a strange new experience for it. In the absence of the crushing forces that it was used to, the rock depressurizes and pops apart in layers like an onion skin – this is called exfoliation, or “onion skin weathering”. This is shown in the cartoon below. ...

Guest Post by Wim Röst ABSTRACT Water, H2O, determines the ‘General Background Temperature’ for the Earth, resulting in Hothouse and Ice House Climate States. During geological periods the movement of continents changes the position of continents
The choice of the E3 metric follows from its immediate interpretation as the physical distance between points in three-dimensional space (for example, it is the distance that seismic waves have to travel within the Earth’s interior). On the other hand, because epicenters are located on a sph...
will be discussed in more detail in the concluding section. Considered in relation to the rest of the themes identified in this quadrant (critique, culture/politics/ethics, governance, and consumption) and the three previous ones, they will be argued to offer several additional layers of much-ne...
The areas with relatively high RSEI values were mainly located in the interior regions of the major islands in the archipelago, while the areas with relatively low RSEI values were mainly distributed in the eastern part of Zhoushan Island, the southwestern part of Jintang Island, the northern ...
