<span>Paleomagnetism is the science of studying the magnetic properties of rocks, sediments, and artifacts which developed in the rocks due to the power and orientation of the earth’s magnetic field while the rocks, sediments and artifacts were being formed. By studying the rocks and sediments scientists can determine when the history of earth’s magnetic field reversed.</span>

Answer:

Paleomagnetism is the study of the history of earths magnetic field in ancient rocks and minerals.

Explanation:

  • This concept was revealed by the French physicist Achilles Delesse in 1849, who detected that certain magnetic minerals in rocks were associated parallel to Earth’s magnetic field. The study of paleomagnetism started in the 1940s when the British physicist Patrick M.S. Blackett  designed a device for calculating the magnetic fields linked with magnetic minerals.
  • Nowadays, two more devices are used to study paleomagnetic materials: the spinner magnetometer and the cryogenic magnetometer. Each of these devices signifies a noteworthy development in the aptitude of a researcher to perceive and measure the magnetic field linked with a mineral.

The core of a mountain range that formed during regional metamorphism would contain a _____ metamorphic facies.
irinina [24]

Answer:

The answer is below

Explanation:

Most metamorphic rocks are formed from regional metamorphism. When two plates collide, it causes the release of large amount of pressure, this causes a deformation (folding and faulting) of the rock. As a result of the collision, the denser plate may be forced under the less dense plate thereby causing the rock to fall deep where they are subjected to high pressure and temperature.

Regional metamorphism produces green schist facies, amphibolite facies and granulite facies.

BIG TIME POINTS!!!!! Only answer if you know the full answer.
Citrus2011 [14]

Answer:

Explanation:

The presence and influence of religion can effect societal standards and the functioning of the government, as well as the laws enforced and instilled by said government, more so the gender roles and values of a society. The economic system and its functioning determines the prosperity and unemployment ratio of a society, all while the presence and power a government has determines how free its citizens are. The more oppressive/restrictive the government, the more tense and often religious a society is or becomes, (i.e Islamic States). All of these factors influence the wealth, strength, global relations, and internal culture of a society.

Explain what power companies in your area are doing to reduce dependence on nonrenewable energy sources.
madreJ [45]

Answer

• Driving a more fuel-efficient car to eliminate “gas guzzling”

• Reducing heating needs

• Reducing lighting needs

Explanation

The three best strategies employed worldwide for conserving non-renewable energy resources are Reduce, Reuse and Recycle( 3R’s). Energy users are encouraged to increase reliance on renewable energies such as solar, wind and geothermal to aid in conserving the scarce fossil fuel that remain.

Walking and biking can be used as a strategy to cut down gas guzzling and manage the limited nonrenewable oil resources. One popular way of heating homes is oil heating. However, the conserve the oil, home owners are supposed to put up storm windows and insulate homes including caulking cracks around doors and windows to reduce heating costs. When using natural gas, users can reduce energy wasting by keeping the thermostat at 70 degrees and shutting off heat when not in use.

Which force acts an an object to move it from rest or a constant, straight-line motion?
Tema [17]
<h2>Answer:</h2>

Balanced forces/Resultant force/ Newton's first law/law of inertia.

<h3>Explanation:</h3><h3>Balanced forces/Resultant force/ Newton's first law/law of inertia:</h3>

It says that each article will remain in its state of rest or similar motion in a straight line except a resultant force works on it. It is known as the law of inertia.

The inertia of the body is the hesitation of the target to alter its state of peace or movement.

The inertia of an article depends on its size. The greater the body, the greater the inertia. It shows it is difficult to start moving, stop, slow down, speed up or change direction. Force is required to overcome inertia.
