Earth Dynamics Review

The region where two tectonic plates meet

• Continental Drift

• Plate tectonics

• Plate Boundaries

The idea that the continents were once part of a single landmass that broke apart and

moved is

• Continental Drift

• Tectonic Plates

• Transform Plate Boundaries

Why did no one believe Wegener's thoery that the continents were once together?

• He could not explain HOW the continents moved

• He didn't have evidence

• His data was wrong

• He didn't use the right technology to gather data

The fact that similar fossils are found on both sides of the ocean is evidence of

• magnetic reversal

• global positioning

• continental drift

• oceanic drift

Answer explanation

The fact that similar fossils are found on both sides of the ocean is evidence of continental drift, where the continents were once connected and later drifted apart.

Which of the following causes Earth's tectonic plates to move?

• Energy from the Sun
• Magnetic Pole Reversal
• Convection currents in the mantle
• Faults in Mountain Ranges

What type of plate boundary is this?

• Plate

• Divergent

• Convergent

• Transform

Answer explanation

The correct type of plate boundary is Convergent where two tectonic plates move towards each other, leading to subduction or collision.

A divergent boundary occurs when plates ....

• Pull apart

• Come together

• Slide past each other

• subducting

Answer explanation

A divergent boundary occurs when plates pull apart, moving away from each other.

Which of the following is NOT evidence to support the theory of plate tectonics?

• Fossils

• Mountains Ranges

• Glaciers

• Sand Erosion

Answer explanation

Sand Erosion is not evidence for plate tectonics as it is not directly related to the movement of tectonic plates.

What geologic feature/event you be most likely to find at a transform boundary?

• Earthquakes

• Volcanoes

• Mountains

• Rift Valleys

Answer explanation

At a transform boundary, you would most likely find earthquakes due to the movement of tectonic plates sliding past each other horizontally.

What geologic feature/event would you most likely to find at a divergent boundary between two pieces of oceanic crust?

• Rift Valley

• Mid-Ocean Ridge

• Island Arc

• Flat land

Answer explanation

At a divergent boundary between two pieces of oceanic crust, you would most likely find a Mid-Ocean Ridge, which is a geologic feature associated with the separation of tectonic plates.
