Why do rocks on the ocean floor form a pattern of magnetized stripes? the rocks contain iron that points in the direction the rocks move away from the ridge. the rocks are composed of different materials depending on when they formed. the rocks change shapes as a result of the pushing and pulling of seafloor spreading. the rocks contain iron that points in different directions depending on earth's polarity.

The striped magnetic pattern develops because, as oceanic crust pulls apart, magma rises to the surface at mid-ocean ridges and spills out to create new bands of ocean floor. Ferromagnetic minerals in the hot magma align themselves with the Earth's magnetic field, which completely reverses its north-to-south polarity every now and then, and freeze in that alignment as the magma cools. Later, after the planet's magnetic field flips again, the next stripe of new ocean floor aligns its polarity in the opposite direction.

Answer:

Effective food supply was most likely an effect on society that resulted from improvements in blood handling during World War I and World War II.

One parrot species that feeds on large seeds nests is in the same tree as a parakeet that feeds on small seeds, they occupy different niches.

Explanation: with a great tolerance to a wide range of conditions the species would adapt and thrive which would allow it to reproduce and have all it needs to survive, grow, and take over.
