The tilt of Earth axis as Earth moves around the Sun
Answer:
Alaska would be the answer
Answer:
Nuclear Fusion that takes place between hydrogen atoms.
Explanation:
The energy comes from the sun and the sun is mostly made up of hydrogen and helium atoms. The sun generates energy from nuclear fusion.
Hydrogen is being converted into helium in the core of the sun. This is called nuclear fusion.
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.
Answer:
inner core- solid hot rock
outer core- magma that suronds the inner core
