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 1
Answer:

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.

The porosity and permeability of soil are influenced by the structure of the soil

What is a Soil Structure?

Soil structure is a word used to describe the arrangement or the way of soil in the solid parts of the soil and of the pore space located between them. It describes the structure of the soil.

Soil structure also describes the way individual particles of sand, silt, and clay are assembled. So the porosity and permeability of soil are influenced by the structure of the soil.

Chains of volcanoes -- all lined up in a row or an arc -- are often produced by plate tectonic processes: collision between two ocean plates; collision between an ocean and a continental plate; a tectonic plate moving over a hotspot; and then also volcanic activity within a continental plate with the real cause being mostly unknown. This question has you match these four processes to locations.

Answers

Explanation:

Final answer:

Chains of volcanoes are formed by different plate tectonic processes. These include collisions between two oceanic plates like the Mariana Islands, a collision between an oceanic and continental plate like the Andes, a tectonic plate moving over a hotspot like Hawaii, and volcanic activity within a continental plate like the Basin and Range Province.

Explanation:

The formation of chains of volcanoes can be attributed to different plate tectonic processes. These include: the collision between two ocean plates, as seen in the Mariana Islands; the collision between an ocean and a continental plate, as exemplified by the Andes Mountain Range; a tectonic plate moving over a hotspot, like the Hawaiian Islands; and finally, volcanic activity within a continental plate whose cause is usually unknown, such as the volcanic field in North America's Basin and Range Province.
