The Earth Similarity Index ( ESI) is a proposed characterization of how similar a planetary-mass object or natural satellite is to Earth. It was designed to be a scale from zero to one, with Earth having a value of one; this is meant to simplify planet comparisons from large databases. The scale has no quantitative meaning for habitability .
Geography of India. / 21°N 78°E / 21; 78. India is situated north of the equator between 8°4' north (the mainland) to 37°6' north latitude and 68°7' east to 97°25' east longitude. [ 2] It is the seventh-largest country in the world, with a total area of 3,287,263 square kilometres (1,269,219 sq mi). [ 3][ 4][ 5] India measures ...
Timeline of Indian history. Chandragupta Maurya overthrew the Nanda Empire and established the first great empire in ancient India, the Maurya Empire. India's Mauryan king Ashoka is widely recognised for his historical acceptance of Buddhism and his attempts to spread nonviolence and peace across his empire.
Due to continental drift, the India Plate split from Madagascar and collided with the Eurasian Plate resulting in the formation of the Himalayas.. The earliest phase of tectonic evolution was marked by the cooling and solidification of the upper crust of the earth's surface in the Archaean Era (prior to 2.5 billion years) which is represented by the exposure of gneisses and granites especially ...
The two lists have been described by Alesina and Ferrara as follows: [ 1] Fearon [ 3] and Alesina et al. [ 4] have compiled various measures of ethnic heterogeneity which try to tackle the fact that the difference amongst groups manifests itself in different ways in different places.
In the 1790s, William Smith hypothesized that if two layers of rock at widely differing locations contained similar fossils, then it was very plausible that the layers were the same age. [16] Smith's nephew and student, John Phillips, later calculated by such means that Earth was about 96 million years old. [17]
Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 19% of Earth's radius [0.7% of volume] or 70% of the Moon 's radius. [ 32][ 33] The inner core was discovered in 1936 by Inge Lehmann and is generally composed primarily of iron and some ...
Structural similarity index measure. The structural similarity index measure ( SSIM) is a method for predicting the perceived quality of digital television and cinematic pictures, as well as other kinds of digital images and videos. It is also used for measuring the similarity between two images. The SSIM index is a full reference metric; in ...
