Most metallic ores are produced by which two types of processes? metamorphic and sedimentary igneous and metamorphic igneous and sedimentary cementation and compaction

Answers

Answer 1
Answer:

Answer:

Metallic ores are produced by igneous and metamorphic processes.

Explanation:

  • Metallic ores are present in every type of rock and few varieties of soil. These get concentrated into "rich masses by igneous, metamorphic processes". Metals precipitate as sulphide minerals in a cooling body of magma.
  • Magmatic deposits occur when the "minerals settle to the bottom" and form layers. Metamorphic deposits rich in copper, cobalt, lead, zinc from hot solutions circulate through the rocks.
  • The solutions come from heated meteoric water. Constant changing pressures result in precipitation of sulphides or pure metal like gold, copper, silver.
  • This process is repeated again and again until the systems are filled with mineral deposits.
Answer 2
Answer: Igneous and metamorphic. mainly igneous.

Which of these statements best explains why Ptolemy's model of the solar system was different from Copernicus' model of the solar system?They had different data to interpret.
They had different interests and backgrounds.
Ptolemy was more creative than Copernicus.
Copernicus was more creative than Ptolemy.

Answers

Answer:

Option (1)

Explanation:

In the Copernicus's model of the solar system, the sun was present at the centre of the universe and all the rest of the planets including the sun, stars revolve around it. Initially, it was believed that the planets move in a circular path, but later after much research, it has been discovered that the planets' orbits are in an elliptical path.

According to the Ptolemy's model of the solar system, the earth was believed to be present at the centre of the universe and all other planets, including the sun and stars orbits around it in a circular path. The earth was considered to be fixed.

Both of them had the same interest but they obtained different data by carrying out different experiments. Due to this, their interpretations were also not the same.

Copernicus's model was accepted widely as it was able to explain the facts that are true regarding the solar system.

Thus, the correct answer is option (1).

They had different data to interpret

The pyrenees mountains have many syncline and anticline structures

Answers

There are numerous syncline and antcline features in the foldedmountains.

What is folded mountain?

The effects of folding on strata in the top section of the Earth's crust result in the formation of fold mountains. The phrase was once used to characterize most mountain belts but has since lost favor due to the advent of the theory of plate tectonics and the lack of knowledge of the interior structure of thrust belts.

In regions of thrusttectonics, such as where two tectonic plates are moving toward one another along a convergent plate boundary, fold mountains develop. If there is a mechanically weak layer, like salt, it can cause the piled layers of rock to crumple and fold like a tablecloth when plates and the continents riding on them meet or undergo subduction.

What are three ways that the density of ocean water can increase?

Answers

three of the most obvious ways the density of an ocean (can be applied to any body of water) are ->

temperature (colder water is denser down to 4 degrees c, but anything between 4 and 0 degrees c is lighter and floats to the top (that's why the top of water freezes before the bottom :) ) )

solute percentage ( in oceans a main solute is salt - we put more salt into the ocean and it gets denser, we filter out the salt and the water gets less dense)

population & pollution ( fish or soda cans don't directly change water density, but the waste products and disolved rust make it denser)

What body of water lies east of the Arabian Peninsula?

Answers

The correct answer is The Persian Gulf which also leads to the Gulf of Oman and the Arabian Sea.

I really hope that this helps you out a lot. Have a very nice day.

Final answer:

The Arabian Sea, which is part of the Indian Ocean, lies east of the Arabian Peninsula. It was a strategically important body of water during the expansion of the Arab empire in the 7th century.

Explanation:

The body of water that lies east of the Arabian Peninsula is the Arabian Sea. The Arabian Sea is part of the Indian Ocean and is bordered on the west by the Arabian Peninsula and on the east by India. The Red Sea lies to the west of the Peninsula, although for a time it came into Arab control and provided access to the Arabian Sea. As the Arab empire expanded during the seventh century, the Arabian Sea and the Persian Gulf became increasingly important for oceangoing vessels, further underlining the strategic value of control over the Arabian Peninsula.
