Answer:

They are named for the places where geologists first described rocks or fossils from that time.

Explanation:

The geological history of planet Earth is divided into multiple eras and periods. The divisions are based on some dramatic event that caused a significant change in a short period of time, thus creating an easy distinction between them. The purpose of the divisions is to be easier for the scientists to explore the past, to find it easier to describe fossils, rock strata, events, etc.

The names of the eras and periods of the geological time scale seem to be names that are familiar, at least to people in some regions, with slight changes at the end of the names. This is because the names of the eras and periods tend to be given by the places where geologists first described rocks or fossils from that time. As an example, we can take the Jurassic (named after the Jura Mountains), Devonian (named after the Devon), Cambrian (named after Cambria, which is the Latin name for Wales), etc.

Although China’s total economic output, measured by Gross Domestic Product (GDP), is third largest in the world, it is considere
vagabundo [1.1K]

Answer:

B. China has a large population , so its GDP per person is only modest

Explanation:

Despite being one of the countries with highest GDP's in the world, and experiencing enormous economic development in the past few decades, China's population is still not having the same level of financial power as the other countries with high GDP's. The main reason for this is that China has enormous population, being the most populated country in the world with over 1.3 billion people. Because of the enormous population, when the money are redistributed to everyone, it turns out that China is still at a level of a developing country. Not to make mistake, China's population has much higher standard of living than what it had few decades ago, so the people live much better, but the country still has a long way to go to reach the GDP's per capita that the other countries have.
