I believe the answer is A
Answer:
Flat-Earth theorists often have explanations for how a disk-shaped ... The problem is that a flat Earth flat out wouldn't work. ... However, if Earth, somehow, were truly flat, it would not behave ... And once you get rid of gravity, everything about our planet rapidly
Hope this helps because I was a little confused too!
Answer:
D. the Amazon River
Explanation:
The Amazon River is officially the second longest river in the world, though there are some people that suggest that it is actually the longest one. This river though is the one that has by far the largest amount of water compared to any other river. The Amazon River is located in South America, and it forms the Amazon Basin where the largest tropical rainforest in the world is located, the Amazon rainforest. This river runs roughly in west-east direction, starting from the eastern slopes of the Andes and ending up in the Atlantic Ocean, with the majority of its flow being through the largest South American country, Brazil.
<span>Fresh water freezes at 32 degrees Fahrenheit, and as salinity increases, the required temperature to freeze decreases.
The freezing point for water at 18 0/00 is 30.233 degrees Fahrenheit. So, for the black sea to freeze, it would need to be less than about thirty and a quarter degrees in both areas. Further for the Adriatic not to freeze it must be assumed that the Adriatic's salinity is higher, probably significantly higher as to avoid even partially freezing.
Furthermore, as the Black Sea's decreased salinity is attributed to nearby freshwater runoff, it is safe to assume that the Adriatic Sea either A) Has little or no freshwater runoff, or B) Has a mitigating factor that negates any freshwater runoff, allowing the salinity of its water to remain high.</span>
1. dust
2. Hubble's constant
3. Local Group
4. Dark matter is massive enough to produce a gravitational redshift and gravitational microlensing in light from nearby stars or galaxies. The mass of visible matter also can be compared to the total mass of a galaxy or cluster. This invisible portion of the total mass is called dark matter.
5. In an expanding universe, objects are moving away from Earth, so the light they emit would have a redshift as observed from Earth. In a decelerating universe, light would have no redshift. Light would have a blueshift in a collapsing universe because all objects in that type universe would be moving toward each other.
