Evidence of Plate Motion

Select the statement that supports evidence from fossils.

• There was one type of fossil found on one specific continent.

• Mountain ranges from different continents' coast seemed to align.

• Fossils found in the Arctic could only survive in tropical climates.

• There were fossils of the same organism found on at least 5 different continents.

The hypothesis of the continental drift happening was rejected for many years until further research. How was the hypothesis of the continental drift accepted?

• Undersea exploration provided evidence that Earth's surface is composed of moving plates.

• Undersea exploration provided evidence that there are deep ocean currents.

• Undersea exploration provided evidence that there are underwater volcanoes.

• Undersea exploration provided evidence that there are mid-ocean ridges.

One piece of evidence for Plate Tectonics is that--

• some continents appear to fit together like a puzzle.

• we have video footage of the plates actually moving.

• all continents have formed from volcanic eruptions.

• the continents are no longer moving.

Which of the following choices did Harry Hess give as evidence to change continental drift to Plate Tectonics? [There is only one answer]

• Fit of continents, rock sequence, glacial evidence

• Identical fossil species on different continents (both plant and animal), Antarctic climate changes

• Sea-floor spreading, mid-ocean ridge, and trenches

Answer explanation

Harry Hess discovered sea-floor spreading, mid-ocean ridges, and trenches many years after Wegener died.

One piece of evidence that supports the Theory of Plate Tectonics is found in the observation of rocks on either side of the Mid-Atlantic Ridge, shown in the picture provided. Plate Tectonic theory is supported because as you move out form the Mid-Atlantic Ridge, the rocks -

• have higher iron content.

• become thicker and thicker.

• are increasingly older.

• are made of smaller particles.
