Structure of Sun:
The sun has six layers.
Three layers named as
• Corona
• Chromosphere
• Photosphere
These layers comprise the sun’s atmosphere or outer layer.
The other three layers namely
• Connective zone
• Radiative zone
• Core
Comprises the inner layer or part of sun that are not seen.
Structure of earth:
The structure of earth is divided into layers and these layers are both physically and chemically different.
The earth has an outer solid layer called crust, a viscous layer called the mantel, a liquid layer that is outer layer called outer core and solid center called inner core.
Answer:
Phobos
Phobos is nearing Mars at a rate of six feet (1.8 meters) every hundred years; at that rate, it will either crash into Mars in 50 million years or break up into a ring.
Explanation:
Answer:
Autotrophs, but not heterotrophs, can nourish themselves beginning with and other nutrients that are inorganic.
Explanation:
Unlike heterotrophs, autotrophs such as green plants, are able to synthesize their food (in form of sugar molecules) starting with inorganic molecules like atmospheric carbon dioxide, water in the presence of sunlight.
This is commonly known as photosynthesis. The equation is shown below
6CO2 + 6H2O --> C6H12O6 + 6O2 + Energy
<u>Answer</u>:
The mass of a star can be determined by studying binary star systems.
<u>Explanation</u>:
In this system it consists of two stars, revolving round the same bary-centre. The systems having two or may say more than two are called as the multiple star system. This zone is also a habitable zone, here the water exists in the liquid form. We could have sometime seen the two stars together. They are also very capable of strengthening the terrestrial planets inside the stable orbital ranges. They have generally two orbits like P-type as well as circumbinary.
