Yoga is one of the six systems of Indian philosophy. The word yoga originates from the sanskrit root yuj which means Union. On the spiritual plane, it means union of the Individual Self with the Universal Self. Yoga is the union of the body, mind, emotions and intellect. Sage Patanjali penned down this subject in his treatise known as Yoga Sutras of Patanjali.
1 Mars probably had a hot liquid core at one time, but because it's a smaller planet its heat dissipated more quickly. 2  They are good candidates for having a protective atmosphere. 3  The atmosphere holds carbon dioxide and other gases that keep the planet warm and protect its surface from radiation.
Without our atmosphere, there would be no life on earth. Two gases make up the bulk of the earth's atmosphere: nitrogen (78%), and oxygen (21%). Argon, carbon dioxide and various trace gases make up the remainder. Scientists divided the atmosphere into four layers according to temperature: troposphere, stratosphere, mesosphere, and thermosphere. The temperature drops as we go up through the troposphere, but it rises as we move through the next layer, the stratosphere. The farther away from earth, the thinner the atmosphere gets.
