Muslims are not terrorists. Some of them are crazy with their religion and they want everybody to be Muslims. People from ISIS are terrorists but they are killing other Muslims too.
Extreme weather events in UK are becoming more common, starting earlier and becoming more intense.
Drought - caused by a lack of rain. Flash floods - caused by too much rain in a short period of time. Strong winds and storms.
Significant storms preclude many workers from being able to report to their jobs and that can create significant declines in revenue for the duration of the inclement weather, or even a much longer period of time. What's more, consumer activity is usually suppressed during extreme weather. An enormous volume of debris dumped by the floodwaters had to be cleaned up and stagnant waters had to be re-oxygenated before being pumped back into rivers. However, worse impact of all was the contamination of all flooded areas by oil, agricultural chemicals, livestock effluent, and human sewage. I think that this is the worst impact because of its potential for causing harm to humans and other animals.
Socio-economic impacts were doubtless very important to the people affected at the time; for example, some of the evacuated residents were still living in temporary accommodation several months after the event. The economic impact will have been felt by the individuals involved as well as the taxpayer, local businesses and the local authorities.
Answer:
A and C
Explanation:
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
