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.
The Earth's atmosphere is ideal for supporting life. Most of the Earth's surface is covered with water. From the sky, the Earth appears blue. Earth is the only inner planet in our solar system that has liquid water on its surface. Seventy percent of the Earth's surface is covered with water. Mountains, volcanoes, deserts, plains, and valleys cover the remaining 30 percent. Earth has an atmosphere made up of many different gases.
