The answer is (A. Afghanistan).
<span>The rock layers must have formed at different times because they contain two different biozones.
The rock layer containing the trilobites must have formed before the one containing the ammonites.
The key thing to note here is that the Trilobites only lived from 540 to 248 million years ago. And that the Ammonites were from 245 to 65 million years ago. So there's a 3 million year gap between these 2 different creatures where neither of them existed. So the dig where the trilobites were found has to be at least 3 million years older than the dig where the Ammonites were found. So with that in mind, let's look at the options and see what makes sense.
The rock layers must have formed at the same time because they both contain biozones.
* This is nonsense no matter what dates you're speaking of. In effect it claims that all rocks that indicate life were created at the same time. So this is definitely a bad choice.
The rock layers must have formed at different times because they contain two different biozones.
* This is technically incorrect since it assumes that all biozones represent an unique period of time which is incorrect. However, since the biozones represented by the presence of Trilobites and Ammonites don't overlap, it is true that these these rock layers were formed at different times. I would have preferred if this option said "non overlapping biozones". But on the balance, I'd consider this option to be true, so it should be selected.
The rock layer containing the trilobites must have formed before the one containing the ammonites.
* This is definitely true since the last Trilobite died about 3 million years before the first Ammonite lived. So this is a correct choice.
The rock layer containing the trilobites must have formed after the one containing the ammonites.
* This is the opposite of the previous option. And since the previous option was true, this option must be false. So this is a bad choice.</span>
Answer:
Well weathe rfront bring in dangerous weather sometimes like tornados or snow storms so we should care for our economy.
Explanation:
I think everyone should be perpared for the weather at all times.
Hope This Helps!

The following are some of the things that may change as the amount of sea ice and glacier coverage on land decreases due to climate warming:
- <em>"The location and strength of the themohaline conveyor".</em>
- <em>"The location and strength of surface currents".</em>
<h3>Why does the climate warm?</h3>
Extra greenhouse gases in the atmosphere are the primary cause of earth's warming. Greenhouse gases like carbon dioxide (CO2) and methane trap heat from the sun inside the earth's atmosphere. It is natural for our atmosphere to include certain greenhouse gases. They contribute to keeping the earth warm enough to support life. In spite of this, too many of these gases in the atmosphere will be harmful to the environment and may contribute to climate change and global warming.
One of the indicators of climate change and global warming is the decrease in sea ice and glacier cover on land.
