Whats the difference between an air mass and a front?

Answers

Answer 1
Answer:

Explanation:

An air mass is a body of air with a relatively constant temperature and moisture content over a significant altitude. Air masses typically cover hundreds, thousands, or millions of square kilometers. A front is the boundary at which two air masses of different temperature and moisture content meet.

Bowen's reaction series Choose one: a) has a continuous series with a progressive change from sodium-rich to calcium-rich amphibole. b) Ocreates a progressively more mafic melt as the magma cools. c) was established by laboratory experiments in the 1920s shows the sequence in which different sulfate minerals form during the progressive cooling of a melt.

Answers

Answer:

None of the above

Explanation:

The Bowen reaction series provides an insight to what happens to a crystallizing magma as it cools. There are two arms in the series, the continuous and the discontinuous series. The continuous series is made of the plagioclase feldspar. At high temperature, calcic plagioclase are crystallized out of the melt and at lower temperature, sodic plagioclase begins to from.

The discontinuous series consists of the trend through which other minerals are crystallized. At high temperature, olivine first forms and quartz is the last to crystallized out.

For a given melt, according to the Bowen's reaction series, the composition becomes more felsic at low temperatures. The silica content increases considerably.

The series is designed for silicate minerals found in nature and not sulfate minerals. The continuous series is for plagioclase feldspars  not amphibole. Amphibole is in the discontinuous series.

EXPLAIN HOW METAMORPHISM CAN ALTER A ROCK CHEMICALLY AS OPPOSED
TO MINEROLOGICALLLY.

Answers

Answer:

The rocks are comprised of cracks and fractures in between the sediments and mineral grains that have the capacity to store fluid in them. This fluid is generally the water that contains various types of dissolved ions. These fluids in the rocks are very much important because the chemical reactions that take place include the change in mineral from one type to another new type. This can highly increase the amount of dissolved ions that are dissolved and transported by the water. This alteration of rock that occurs chemically due to these fluid refers to the process which is commonly known as the metasomatism. Whereas, the rock alters mineralogically due to the increasing temperature and pressure condition, that changes the grade of rocks.

This is how metamorphism alters the rock chemically in comparison to mineralogically.

HELP whoever first gets a brainiestHow did the ancient Egyptians apply their knowledge of astronomy?

They built the pyramids.
They developed a calendar.
They wrote medical textbooks.
They created a process for embalming.

Answers

Answer:

The Egyptians showed their knowledge of astronomy in that they developed a calendar.

Explanation:

The building of the pyramids and their meaning and usage is still heavily debatable, so we can not take this option as correct per se.

The development of the calendar is correct because it was based directly on the knowledge of astronomy and the movement patterns of the space objects.

The medical textbooks have been a product of the development of medicine, so it is not a correct option.

The embalming was a process used for the passed away nobles in order to prepare them for the afterlife, so it is not correct.
