Theory of Plate Tectonics

As two continental plates collide, the edges of the plates are crumpled and uplifted. Which of these landforms are MOST likely a result of this type of collision?

• Normal faults

• Mountain Ranges

• U-shaped valleys

• Shield Volcanoes

As early as the 1600's, scientists noticed that the continents appeared to fit together like pieces of a puzzle. The idea that the continents were once together and had drifted apart was not widely accepted. In the 1940'2 technology used on submarines led to evidence of continental movement. This technology allowed the scientist to do which of the following?

• to explain the causes of continental movement

• to determine fossil evidence of continental drift

• to prevent further movement of continents

• to reject theories of continental drift

How did scientists arrive at the theory of plate tectonics?

• by determining the age of lava rising at ocean ridges

• by determining the composition of limestone deposits

• by determining the rate of weathering of mountain ranges

• by determining the type of sedimentary rock formed on land

• Convection currents

• Molten rock

• Radioactive isotopes

India was once its own continent. According to the theory of continental drift, India collided with and became a part of Asia. This caused

• glaciers in the area to melt

• large mountain ranges to form

• deep mid ocean trenches to develop

• deserts in the area to become fertile
