Unit 2: Plate Tectonics Review

What is a transform boundary?

• A tectonic plate boundary where two plates slide past each other horizontally.

• A tectonic plate boundary where two plates move away from each other.

• A tectonic plate boundary where two plates collide and create mountains.

• A tectonic plate boundary where one plate is forced under another.

What is the Ring of Fire?

• A major area in the Pacific Ocean where many earthquakes and volcanic eruptions occur.

• A famous mountain range in Europe.

• A type of ocean current that affects climate.

• A region known for its tropical rainforests.

What drives the movement of tectonic plates?

• Convection currents deep in the mantle.

• Gravitational pull from the moon.

• Wind patterns in the atmosphere.

• Ocean currents on the surface.

What are tectonic plates?

• Large sections of the Earth's lithosphere that move and interact with each other.

• Thin layers of soil that cover the Earth's surface.

• Massive bodies of water that separate continents.

• Atmospheric layers that protect the Earth from solar radiation.

What is a convergent boundary?

• A tectonic plate boundary where two plates collide or move towards each other.

• A tectonic plate boundary where two plates move apart.

• A tectonic plate boundary where two plates slide past each other.

• A tectonic plate boundary that is stationary and does not move.

What causes Earth's tectonic plates to move?

• Convection currents in the mantle.

• Gravitational pull from the moon.

• Earth's rotation on its axis.

• Magnetic fields in the core.

How do temperature, pressure, and density change from the inner core to the crust?

• They all increase.

• They all decrease.

• Temperature increases, pressure decreases, density increases.

• Temperature decreases, pressure increases, density decreases.

What role do convection currents play in plate tectonics?

• They drive the movement of tectonic plates by transferring heat from the Earth's interior.

• They cause earthquakes by creating pressure at plate boundaries.

• They are responsible for the formation of mountains and valleys.

• They have no significant impact on plate tectonics.

What is a divergent boundary?

• A tectonic plate boundary where two plates move away from each other.

• A tectonic plate boundary where two plates collide.

• A tectonic plate boundary where one plate slides under another.

• A tectonic plate boundary that remains stationary.

What is the best evidence that continents were once connected?

• Matching rock types, fossils, and coastlines.

• Similar climate patterns across different continents.

• The presence of large mountain ranges on separate continents.

• The distribution of modern animal species.
