Answer:
Explanation:
Can you think of a solid that can flow?
You use one twice a day! Toothpaste is a solid that can flow. Is the asthenosphere made of toothpaste? Only if the
toothpaste is ultramafic in composition, and then it would only be able to flow if it were really, really hot. Still the
toothpaste analogy gives you a good image of how the asthenosphere might behave if you squeezed it!
Lithosphere
The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid
solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is
about 100 kilometers thick. How are crust and lithosphere different from each other?
 
        
             
        
        
        
Answer: 
Composition: mostly hydrogen and helium gas 
Mass: 1.989 × 10³⁰ kg 
Explanation: 
Sun is a star at the center of the solar system. It is mostly composed of Hydrogen and Helium gases. Fusion of Hydrogen into Helium in the core powers the sun. Huge amount of heat and light energy is liberated. The mass of the Sun is 1.989 × 10³⁰ kg. Sun is a Population I star.
