The red sea presents a simple geometry of an elongate oceanic basin. volcanic rocks along both shores of the red sea display similar ages of ~20 million years. examine the shape of the shoreline of red sea. what type of tectonic environment is present at the red sea?

The earth's magnetic field, with a magnetic dipole moment of 8.0×1022am2, is generated by currents within the molten iron of the earth's outer core. suppose we model the core current as a 3000-km-diameter current loop made from a 1000-km-diameter “wire.” the loop diameter is measured from the centers of this very fat wire.to decide whether this is a large or a small current density, compare it to the current density of a 7.0 a current in a 2.0-mm-diameter wire.

Electromagnetic force is present when electromagnetic fields a.become charged as they lose electrons. b.become stable as they come in contact with other forces. c. interact with charged particles. d.gain energy from other forces.
