Plate Tectonics.

Plates-the lithosphere broken into several large slabs



Plate tectonics theory- the plates are moving.

Summative Statement

I think this theory is valid because if you take a look at are earth it makes sense and the evidence provided helps it make sense too, what i mean by that is it says the lithosphere is broken into large slabs which are called plates and they move. i think this is valid because how eles would mountains and other landscapes be made if the plates didn't move and glide together.

Continental Drift

Summative Statement

I think this theory is valid because they had proof of the same fresh water animal fossils, plant fossils and similar rocks all found on the different continents.

Seafloor Spreading

Summative Statement

i think this is a valid theory because they have proof of the ocean rock ridges being there and all the information they give and state is real not false.
