Answer:
Explanation:
True:
The universe's average temperature and rate of expansion support the idea that it began as one super-dense and hot mass 13.8 billion years ago.
This is true because it is exactly how we know how old the universe is, it is also how we know it began "at a point" or at least that it used to be very dense.
False:
Human life is more valuable than other forms of life on Earth because humans are more intelligent than other organisms.
What this is implying is that somehow we are better than other organisms. There is no evidence that supports this claim.
True:
Ocean tides are caused by the uneven gravitational pulls of the Moon and Sun on different parts of Earth.
This is why there are tides and it has direct evidence.
False:
The opinions of randomly selected participants in a survey prove the idea that global temperatures are not increasing on Earth.
What people think (most of the time) is wrong. People can "know" things but that doesn't mean they are true. this is what neil degras tyson calls a "self truthe". You can't base your claim off of what people claim rather you should do a real scientific experiment.
