What is one reason we have stripes of alternating magnetism on the ocean floor?(1 point)
Responses

Magnetic direction of rock changes as Earth’s magnetic poles drift and reverse.

Plates move as new rock forms, which causes magnetic direction to skew away from normal.

Rock is constantly being destroyed at the mid-ocean ridge on the ocean floor

Minerals in magma match the magnetic direction present on Earth when it hardens into rock

Geologist discovered fossils of identical spider mites from the same time period but on opposite sides of the ocean from each other. What conclusion is supported by the discovery of these fossils?(1 point)
Responses

The climate was much cooler during the time that the mites lived.

The locations of the fossils were once much closer to each other.

The mites were extraordinary swimmers.

The locations of the fossils were once vast swamp lands.
