Volcanic and other such activity at the mid-Athletic ridge extrudes material to fill the gap between separating tectonic plates associated with continental drift. The magnetization of rocks is found to reverse in a coordinated manner with distance from the ridge. What does this imply about the Earth's magnetic field and how could the knowledge of the spreading rate he used to give its historical record?

What does this imply about the Earth's magnetic field?

Answer to Problem 1CQ

It implies that there is no magnetic force at the center of the earth where molten metal is present, and also suggest that there is a strong magnetic field outside the earth under the influence of which the earth gets magnetize.

Explanation of Solution

When the molten lava comes out form the volcano, it gets solidifies into a rock and it get magnetize in the direction of the local magnetic field, and at the center of the lava there is no magnetic field.

Similarly, it indicates that when the earth is in molten state there is no magnetic field, but as it starts cooling the outer layer of the earth gets magnetize under the influence of strong magnetic field. It also implies that there is a strong magnetic field outside the earth due to which the earth gets magnetize at the North and the South Pole.

Conclusion:

It implies that there is no magnetic force at the center of the earth where molten metal is present, and also suggest that there is a strong magnetic field outside the earth under the influence of which the earth gets magnetize.

13.87 ... Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…
