Explanation: In an otherwise undisturbed sequence of sedimentary strata, or rock layers, the layers on the bottom are the oldest and layers above them are younger. Principle of Original Horizontality: Layers of rocks deposited from above, such as sediments and lava flows, are originally laid down horizontally. Hope this helps!
Answer:
here you go
Explanation:
One important discovery that geologists made when studying such igneous rocks was that some of the rocks recorded reversals in the direction of Earth's magnetic field. ... Geologists also studied the magnetic record of the rocks of the ocean floor, particularly the igneous rocks on the sides of mid-ocean ridges.
and one more
Scientists discovered that the rock that makes up the ocean floor lies in a pattern of magnetized Stripes. These 'stripes' hold a record of reversals in the Earth's magnetic field, as the rock is cooled, the iron bits line up in the direction of Earth's magnetic field.
Answer:
Answer is 2. reinforcing the field.
Refer below.
Explanation:
Assume you wrap a wire around Earth’s equator at an altitude of 200 kilometers and run an electric current through it in the westerly direction. The effect on the Earth’s natural magnetic field at the Earth’s surface is reinforcing the field.
