Group of answer choices.
A. Weather on Earth's surface
B. Rotation of Earth on its axis
C. Metal liquifying in the inner core
D. Revolutions of Earth around the Sun
E. Rock solidifying in the outer mantle
F. Motion of metal in Earth's outer core
Answer:
B. rotation of Earth on its axis.
F. motion of metal in Earth's outer core.
Explanation:
The phenomena which help form Earth’s magnetic field includes;
I. Rotation of Earth on its axis.
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis.
This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
II. Motion of metal in Earth's outer core.
When planet earth spins on its own axis, the iron found within a liquid outer core moves around which typically gives rise to powerful electrical currents to be generated inside the liquid iron.
B, C, D, E, G are all parts of a financial plan.
Answer:
oil produces CO2
coal produces CO2
uranium does not produce CO2 aka nuclear reactors as this process requires dipping the uranium rods into water creating steam and turning a turbine making energy
natural gas does create CO2 but less than coal and oil that is why natural gas is preferred as a energy source
Explanation:
<span>The stars change position in the sky through the course of the night just like the sun changes position in the sky through the course of a day, they rise in the east and set in the west. If you were to start watching a star in the east at the beginning of the night and keep observing that same star for hours, you will see the star's position move across the sky and eventually drop below the western horizon. There some stars that don't rise and set through the night though. The stars near the celestial pole move in circles around the pole. There is one star in the sky that doesn't appear to move at all, because it is located in line with the Earth's axis of rotation, or in other words, on the celestial pole. This star is Polaris, or more commonly known as the North Star. The south celestial pole currently lacks a star so there is no southern hemisphere counterpart. In reality, Polaris isn't perfectly on the celestial pole so even it moves in a very small circle too small to be seen with the naked eye.</span>
