The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K. In the inner solar system, only substances with very high melting points would have remained solid. All the rest would have vaoprized. So the inner solar system objects are made of iron, silicon, magnesium, sulfer, aluminum, calcium and nickel. Many of these were present in compounds with oxygen. There were relatively few elements of any other kind in a solid state to form the inner planets. The inner planets are much smaller than the outer planets and because of this have relatively low gravity and were not able to attract large amounts of gas to their atmospheres. In the outer regions of the solar system where it was cooler, other elements like water and methane did not vaporize and were able to form the giant planets. These planets were more massive than the inner planets and were able to attract large amounts of hydrogen and helium, which is why they are composed mainly of hydrogen and helium, the most abundant elements in the solar system, and in the universe

B. energy conservation
C. energy transformation
D. Other:
Answer:
Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another. While energy can be transferred or transformed, the total energy always remains the same.
Explanation:
-Magnetism surrounding the wire weakens the magnetic force of the pole.
-Magnetism surrounding the wire draws the needle toward the wire.
c. mesosphere
b. stratosphere
d. exosphere
Answer: d. exosphere
The exosphere is the outermost layer of the atmosphere of earth. It is present above the thermosphere which is lying above the earth. From this layer, the atoms and molecules escape out, which maintains an environment for the movement of satellites and space shuttles.
