adoni · Answer

Which choices do you think we can eliminate right away?

tylermckinney16 · Answer

C?

adoni · Answer

Are you asking whether C is the answer to the question or whether we can eliminate C as a possible answer?

tylermckinney16 · Answer

Eliminate it it was i meant.

adoni · Answer

I'm not so sure we should eliminate that one just yet. 

Let's go through the other options to see if we can eliminate them. 

So for the first choice, 'static' means 'unchanging'. 
Has the Earth changed at all since it was formed?

tylermckinney16 · Answer

Not really.

adoni · Answer

Really? 
It has changed quite a bit, actually... 
From Pangea (back when all continents were one) to our now separate continents, which are still moving to volcanoes erupting, creating new islands, destroying human civilizations, to all of the damage humans have done to the Earth.

tylermckinney16 · Answer

True lol.

adoni · Answer

So we can eliminate the first choice. 

Now, for the second choice:

'invulnerable' means that it it isn't able to be harmed by humans. 
Is this true?

tylermckinney16 · Answer

Im thinking no.

adoni · Answer

No, the Earth is quite vulnerable to humans. 
Some examples to show would be our atmosphere itself; we have caused so much damage, that we've caused our ozone to have holes, which results in the 'greenhouse affect' (global warming). 
That's just one of many examples.

adoni · Answer

So, we can also eliminate the second choice.

adoni · Answer

Now, looking at the last choice, what do you think? Can Earth's history be analyzed?

tylermckinney16 · Answer

Yeah it can be analyzed.

tylermckinney16 · Answer

Hmm wait.

adoni · Answer

You're right, it can be analyzed. 
Scientists can examine fossils to help analyze what Earth was like back in those days.

tylermckinney16 · Answer

Ok cool.

adoni · Answer

So, we can eliminate that one. 

What does that leave us with?

tylermckinney16 · Answer

C

adoni · Answer

That's right. 
Do you know why C is correct though?

tylermckinney16 · Answer

Yeah thanks :)
