Anorthosites, almost entirely made of plagioclase feldspar, are the Moon's earliest rocks. They appear to have developed when feldspar crystallised and floated to the top of the Moon's early magma ocean.

Anorthosite is an intrusive igneous rock made primarily of calcium-rich plagioclase feldspar. All anorthosites found on Earth are coarse crystals, but some Moon samples are finely crystalline. It is almost entirely composed of plagioclase feldspar, a standard, light-weight, light-coloured mineral on Earth. It is an igneous rock that cools and solidifies from hot melting material. This mineral floated to the surface and created anorthosite. Anorthosite is a significant rock type on the Moon's surface, accounting for most of the highlands and crust. This sample, recovered by Apollo 16 astronauts, has been proven to be 4.19 billion years old.

The eastward migration of Russians to the Pacific coastal zone since 1991 has been so great as to overburden the available accom
vagabundo [1.1K]

The correct answer is B. False

Explanation:

Russia is considered the largest country in the world, located in both Asia and Europe. In terms of population, most of the Russian population is now located in the western zone of the country or in Europe, which includes cities such as Moscow or St. Petersburg. Despite this, since the 19th century and especially during the Soviet Union period there were migrations of Russians eastward or towards the Pacific coastal zone, which led to the creation of Russian settlements in new zones.

However, in the last decades, this migration pattern has decreased and settlements in the east are still small in comparison to those of the west. In this context, the eastward migration has not been a huge phenomenon since 1991, and even if there is still migration and the government promotes this, it has not led to a lack of accommodations or restrictions, which makes the statement false.

Which is the best label for the dotted-line arrow? force of Earth’s gravity moon’s attraction to the Sun moon’s motion without g
inysia [295]

Answer:

The Effects of Earth's Gravity on the Moon. Earth exerts an gravitational effect on the moon that is 80 times stronger than the moon's pull on Earth. This massive gravitational pull caused the surface of the moon to bulge toward Earth, similar to how the moon causes large bodies of water on Earth to bulge

The gravitational pull of the Sun on the Earth is greater than the gravitational pull of the Moon, about 180 times as large due its much greater mass, as explained in class. The tides, however, are caused by the differences in gravitational forces by the Moon on opposite sides of the Earth

Which conclusion about oceanic languages is best supported by the data in the table
andrey2020 [161]

All Oceanic languages belong to the same language family, the Austronesian language family.

Explanation:

The Oceanic languages are languages that are dispersed all over Oceania, occupying one of the largest linguistic areas in the world. Despite occupying such vast area, there are only around 2 million speakers of these languages, as the native populations on the islands in Oceania are not large in general. There are over 450 Oceanic languages, and they are part of the Austronesian language family, and tracing their origin in the Proto-Oceanic language.

The three regions where these languages are spoken are Melanesia, Polynesia, and Micronesia. It is no wonder that the people from these three regions have languages from the same family, as they all share common ancestors, so as they were diverging, the language was just developing in a slightly different way, but still keeping the basics. These languages can be grouped into:

  • Admiralties and Yapese
  • St. Matthias
  • Western Oceanic
  • Temotu
  • Central Eastern Oceanic

The largest individual language by people that speak them are:

  • Eastern Fijian
  • Samoan
  • Kiribati
  • Tongan
  • Tahitian
  • Maori

Dmitriy789 [7]

Answer:

Development.

Explanation:

Development can be defined as the progress of a country as it becomes more economically, technologically advanced and improvements in people's quality of life.

Some of the economic development indicators are demographics, gross domestic product (GDP), unemployment, economic structure, gross national product (GNP), inflation etc.

Basically, development is considered to be a microeconomic element.

Macroeconomics can be defined as the study of behaviors, performance and factors that affect the entire economy. Hence, it focuses on aggregate phenomena such as price level, economic growth, Gross Domestic Product (GDP), inflation, unemployment and national income levels with respect to the central bank, demand or supply shocks, government policies, aggregate spending and savings.
