Devin had a bucket of shredded metals the metals consist of aluminum steel and copper he tried sorting the mixture by running it through a filter but this did not sort the mixture into separate components what can devin conclude

Devin's problem can be solved by exploiting the activity series of metals.

Explanation:

This determines what metals are more reactive and would be readily displaced in a reaction.

Seeing as they are both metals scraps of similar sizes, filtration isn't a solution.  But since Copper is lower on the activity series than Aluminium, adding an acidic solution (say tetraoxosulphate VI solution) to the mixture, would have aluminium in solution and Cu as residue which can then be filtered off.

I hope this was helpful.

the gradual movement of the continents across the earth's surface through geological time.

Plate tectonics is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of Earth's lithosphere,

the formation of fresh areas of oceanic crust which occurs through the upwelling of magma at mid-ocean ridges and its subsequent outward movement on either side.

the sideways and downward movement of the edge of a plate of the earth's crust into the mantle beneath another plate.

In 1912 Alfred Wegener (1880-1930) noticed the same thing and proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.

Several types of evidence supported Hess's theory of sea-floor spreading: eruptions of molten material, magnetic stripes in the rock of the ocean floor, and the ages of the rocks themselves. This evidence led scientists to look again at Wegener's hypothesis of continental drift.
