Question

1. alfred wegener had a theory about the continents and their history, but like any good scientist, he did not only base this theory on one fact. he had many observations that he based this theory on. which of the following is not an observation that wegener made?

the continents appear to fit together.
identical rocks, of the same type and age, are found in mountain ranges on both sides of the atlantic ocean.
ancient fossils of the same species of extinct plants and animals are found in rocks of the same age but are on continents that are now widely separated
the bottom of the ocean has ridges, and in the center of these ridges there is hot, young igneous rock. farther away from the ridges there is colder, older igneous rock.

Explanation:

Alfred Wegener proposed continental drift in the early 1900s. His observations included continental fit, matching rocks, and identical fossils across separated continents. The ocean ridge data (hot young rock at ridges, older rock farther away) relates to seafloor spreading, a later discovery (1960s) that supported plate tectonics, not Wegener's original observations.

Answer:

The bottom of the ocean has ridges, and in the center of these ridges there is hot, young igneous rock. Farther away from the ridges there is colder, older igneous rock.
