Which describes the effects of population increase and resource depletion
Setler [38]

Answer AND Explanation:

As the population increases, the amount of resources are depleted. Inadequate resources makes the population growth to stop. With a high population, death rate increases due to starvation and diseases which spread more easily in a large population. There may be a decrease in birth rate due to fewer matings and abortions resulting from social stress.

The magnetic particles in seafloor ridges are aligned differently in a repeating pattern. How
Mademuasel [1]

A. Earth's magnetic field reverses over time;  the changes show that seafloor spreading  has taken place over time.

Explanation:

The pattern of the magnetic minerals in seafloor ridges are aligned in a repeating pattern because the earth's magnetic field reverses overtime.

This provides evidence because the changes shows that the sea floor spreading has taken place over time.

  • The concept of sea floor spreading was first suggested by Harry Hess in the early 1960's.
  • Using sophisticated tools, he was able to discover stripe patterns of magnetic minerals in rocks.
  • The earth can be likened to a giant bar magnet
  • The geomagnetic field originates from the core where the movement of molten metals induces magnetism.
  • In a fresh cooling magma, the metallic minerals are able to align their domains with the prevailing magnetic field.
  • At some point the magnetic field is normal with a very strong intensity. At other times the intensity is low and it reverses.
  • The minerals keeps track of the changes.
  • This leads to striped pattern that has been used to suggest sea floor spreading.

Describe the strength of the magnetic field at points a b and c in the image below. Explain your answers in the terms of magneti
Nastasia [14]

The magnetic fields are strongest at point A and weakest at point C. The magnetic field lines can be used to indicate the strength of a magnet or magnetic field. The closer together the magnetic field lines the stronger the magnetic field.

Explanation:

The magnetic field line also shows the direction of the magnetic field, hence they are also considered vector fields because they have magnitude and direction. They usually have an arrow indicating that the field lines are moving from the north pole to the south pole. The lines also never cross and are always in closed loops.
