Answer:
d) <u>Distance and density are in exact agreement</u>
Explanation:
- Distance From the sun is related to the density of the planets as most of the terrestrial planet have rocky cores and are made up of solid metals so, the density remains stable as the case of the earth having a density of 5.5g/cm cube.
- Planets near to the sun like the mercury have a density of 5.4g/cm cube and planets away from the sun like Saturn have a density of 1.2g/cm cube and Jupiter has 1.3g/cm cube. Thus it can be estimated that the nearness to the sun impacts the amount of the gases and gravity the planets can absorb.
- Four least dense planets are Saturn, Uranus, and Neptune, and Jupiter the farther we go density decreases as these planets tend to made entirely on gas and condensed icy crystals. As the solars winds blow away the gases from terrestrial planets
Answer:
D: The inner core is liquid and moving.
Explanation:
Alexander III of Macedon (Alexander the Great), apart from being a great military tactician and in a way promoted some initial version of globalization, he was also an explorer.
With his conquering, Alexander and the Macedonian soldiers managed to reach parts of the world that were either unknown, or were things of legends and myths in Europe.
Multiple people that were historians, philosophers, or were interested in any science were writing down pretty much everything, and they also were trying to make maps of the newly discovered places, which gave the people in Macedon, and all the others from the region that the world is much bigger than they thought previously.
