How do magnetic stripes of iron in ocean rock provide evidence of seafloor spreding A. They show when Earth's poles reversed.
B. They show how the density of the seafloor has changed
C. They revel matching pattern on either side of the ridge
D. They revel differences in the mineral composition of newly created rock.

The correct option is;

C. They revel matching pattern on either side of the ridge

Explanation:

The reversing of the poles in the Earth's magnetic field are stored stored in solidified molten rocks that become buried underneath the Earth's surface and in the bottom of the ocean in the form of magnetic memory.

With the aid of instruments that are able to record magnetic memory in rocks, scientist where able to find similar alternating pattern of rocks bearing stripes of magnetic field when the Earth's magnetic field was oriented northwards direction alternating with rock with stripes formed in the period when the Earth's magnetic field was oriented in the Southwards direction on either side of the ridge on the seafloor.

here are five steps to a strong outline:

choose your topic and establish your purpose. a lot of writers struggle to define the initial focus for their paper.

create a list of main ideas. this is the brainstorming part of the writing process.

organize your main ideas.

flush out your main points.

review and adjust.
