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.
Quick Answer. Earthâs atmosphere protects life on the surface by filtering deadly ultraviolet radiation, destroying most meteors that pass through it and retaining heat. The atmosphere also provides oxygen to humans and carbon dioxide to plants. The atmosphere consists of five layers and is approximately 60 miles thick. The layer closest to the surface is called the troposphere, and it provides the majority of the planetâs oxygen. This layer is also responsible for weather, including rain, which protects Earth's inhabitants from drought and starvation.
