Answer:
geomagnetic field.
Explanation:
The earth magnetic field can be likened to a bar magnet with a North and South pole. It originates from the movement of molten iron and nickel in the outer core.
At every point in time, the magnetic field orientation can change. We must note that the magnetic north lies close to that of geographic north axis of the earth.
Around the mid-oceanic ridges, new materials are brought to the surface. These new materials can contain magnetic minerals such as haematite which are capable of being magnetized as a result of the prevalent magnetic field of the earth. As different materials are brought up, the magnetic minerals preserves the details of the magnetic field at that point in time. Using this information can know the orientation of the magnetic field at any point in time if the magnetic history chart of the earth is constructed. Oceanic ridges becomes older as they move away from the divergent margins.
The correct answer is c. almost encircles the Ordos desert.
The Huang He River has an interesting circle like movement around the western, northern and eastern part of the Ordos desert, which almost makes it look like it is wrapping the Ordos desert around with it's waters.
C.?
Because the school with students, with high grades, means smarter, and better?
or D.
Not sure, lol
Answer: sinking or rising
Explanation:
This band of bright clouds in the equatorial region is an indication of sinking or rising air. The band generally marks the locations where surface winds in the Northern and Southern Hemispheres blowing towards the equator meet. Called the ITCZ (Intertropical Convergence Zone), the band of cloudiness is characterized by the bright clouds indicating intense thunderstorm activity and by high rainfall rates. It roughly parallels the equator around the globe.
