  in the same time period

Multiple Choice

In 1997 a team of scientists discovered three fossilized skulls and other artifacts at a dig site in Ethiopia, Africa. Since it is difficult to determine the age of once-living organisms, the scientists used radioactive dating on the igneous rocks that surrounded the remains to determine their

• Radioactive dating determines whether the igneous rocks are older or younger than

  deeper layers of rocks, while the using the law of superposition depends on tectonic

  events.

• The two equally dense tectonic plates separate, allowing magma from the crust to flow

  upward and out of the opening that formed between the two plates.

• The more dense oceanic crust is forced under the less dense continental crust, which

These remain the same no matter how big or small the sample or amount of matter.
