The Earth's Magnetic Field Is Best Described as
The regional field is the sum of Earths field and induced fields from features larger than the survey area. Which best describes Earths magnetic field lines.

For more precise work or for any work at higher L-shells a more accurate model.
. 2 See answers Advertisement Advertisement amberewalded amberewalded. The earths south magnetic pole is actually near the North Pole and the magnetic north pole is in Antarctica. Field lines resonate in a circular pattern from the magnetic north and south poles.
D The ocean floor is spreading apart and new sea floor is forming. The magnetic north pole is the point from where the magnetic field of the Earth points downwards in the vertical direction. Earths geomagnetic field extends from its inner core to space.
Due to effects of the interplanetary magnetic field and the solar wind the dipole model is particularly inaccurate at high L-shells but may be a good approximation for lower L-shells. B The igneous rock of the ocean floor preserves Earths existing magnetic field as the rock cools. The magnitude of the magnetic field ranges between 25 and 65 microteslas and is presented as a magnetic dipole tilted at approximately 11 degrees from the Earths rotational axis.
A magnetic field is a vector field that describes the magnetic influence on moving electric charges electric currents and magnetic materials. The interior of the Earth generates the magnetic field through a process called geodynamo. The outer core also has hurricanes--whirlpools powered by the Coriolis forces of Earths rotation.
The Earths magnetic field just did something scientists rarely see. The magnetic field gives us a layer out in space called the magnetosphere high above in the atmosphere. 2 See answers Advertisement Advertisement 00Renรฉe00 00Renรฉe00 The field lines go out of earth near Antarctica enter earth in northern Canada and are not aligned with the geographic poles.
From space the magnetosphere resembles a magnetic dipole. Earths magnetic field is also referred to as the geomagnetic field. Which best describes earths magnetic field lines.
The wave was detected by. The regional field consists of those magnetic effects caused by very large geologic features. The magnetic fields have an extension.
The magnetic field of Earth is caused by currents of electricity that flow in the molten core. The dipole model of the Earths magnetic field is a first order approximation of the rather complex true Earths magnetic field. The powerful magnetic field passes out through the core of the earth passes through the crust and enters space.
A The polarity of Earths magnetic field experiences reversals. Magnetic fields surround magnetized materials and are created by electric currents such as those used in electromagnets and by electric fields varying in time. Sitting atop the hot inner core the liquid outer core seethes and roils like water in a pan on a hot stove.
The earths magnetic field extends millions of kilometers into outer space and looks very much like a bar magnet. It varies in distance but can extend up to 65000 kilometers from Earths surface. There is a gradual change in the magnetic poles with the passing of the time.
Its magnitude at the Earths surface ranges from 25 to 65 micro Tesla. The field lines go out of earth near the north pole enter earth in the south pole and are not aligned with the geographic poles. These currents are hundreds of miles wide and flow at thousands of miles per hour as the earth rotates.
The regional field is Earths magnetic field. Earths magnetic field is the magnetic field that extends from the Earths interior to where it meets the solar wind a stream of charged particles emanating from the Sun. Just took the test on edge 2020.
Question 4 2 out of 2 points This type of coal burns the hottest and typically has the fewest amount of impurities. C Polar reversals cause existing ocean crust to remagnetize. Earths magnetic field comes from this ocean of iron which is an electrically conducting fluid in constant motion.
