Scientists theorized that the continents were once joined together even before they had modern evidence from rocks and fossils. Using only maps, they observed that -

• continents with the most temperate climates were found near the Equator.

• the oceans have become smaller throughout the history of Earth.

• the shapes of continents appeared to allow them to fit together.

• most of the larger land masses are in the Northern Hemisphere.

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.

The Dead Sea to the north of Africa has formed where land is thinning and sinking. This is a result of the interaction of tectonic plates. The Dead Sea -

• is located in the center of a rotating plate.

• sits on a boundary between plates moving apart.

• formed where one plate covers another.

• formed from melting due to solar radiation.

The earthquakes experienced in California are related to tectonic plates because these catastrophic events are the result of -

• two tectonic plates sliding past each other.

• tectonic plates melting as they slide into the mantle.

• tectonic plates being weathered over time.

• two tectonic plates pulling away from each other.

One piece of evidence that supports the Theory of Plate Tectonics is the discovery of what in both South America and Africa?

• The ancient atmosphere in both places was identical.

• The rates of weathering of rock are similar.

• Fossil remains of the same land-dwelling animal.

• Plants on both continents have similar flowers.

Which of the following features is likely to form where two tectonic plates push toward each other?

• Ocean shoreline

• Mountain range

• Mid-ocean ridge

• Rift valley
