Answer is B and D are the best answers

According to researchers, this theory is believed to have started 4.6 billion years ago. However much we shed light on theories that took place up to 3 billion years ago, the plate tectonic theory is not suffient enough to explain the earth's and crust formation before 1 to 3 billions years ago through to the earliest formation of planet 4.6 billion years ago. The difference with these numbers are big and it is simply hard to find well-preserved ancient rocks

The correct answer is - Rocks that are old are hard to find.

In order for the scientists to be able to study the beginnings of the plate tectonics they need a physical proof. The problem is that the oldest pieces of rocks have been subducted sometimes in the past, thus recycled in the mantle, so the proof is long gone. The oldest rocks on the planet, usually found deep into the mainland of the bigger land masses, are very rare, and very small, and on top of that, even though they are the oldest pieces of rocks, they are not the first ones that appeared, at least that is what is thought.

How does the study of populations affect me?
densk [106]
One way in which the study of populations ( human populations - I assume) affects us is that they can help predict the population size in the future and prepare us for it. For example, if we see that the population is decreasing, a country might want to consider supporting child-bearing or immigration to avoid the problem of too many people receiving pensions but not paying taxes.

What is the island in the atlantic off the northwestern coast of mainland europe?
RUDIKE [14]
<h2>Answer: British Isles </h2>

The British Isles are an archipelago (Great Britain and Ireland, and other smaller islands) located at the northwest of the coast of Europe. They are separated from the European continent by the North Sea to the east and by the English Channel to the south, while to the west and north they border the Atlantic Ocean.

However this was not always in this way. Millions of years ago this portion of land was a peninsula linked by a limestone mountainous ridge to mainland Europe. This is how, where the current Dover Strait is located, there was a rock formation that joint Great Britain and France.

It is estimated that it was at the end of the last Ice Age (this whole area was frozen and the sea level was far much lower than today) that this territory began to separate from the continent, a process that ended in the Mesolithic period, in the middle of the Stone Age, becoming the insular territory we know today.

In fact, the current Irish Sea and the North Sea were dry land that was submerged with the rise of sea level in the thaw.
