Identify the type of plate boundary where two tectonic plates move away from each other.
Convergent boundary
Divergent boundary

Subduction zone
Explain how mountain ranges like the Himalayas are formed.
By the erosion of large landmasses over millions of years.
By the collision and convergence of continental plates.
By the accumulation of volcanic ash and lava.
By the deposition of sediment in ocean basins.
What is an accretionary wedge, and how does it form?
A pile of sediment that forms at a divergent boundary due to sea-floor spreading.
A mass of sediment and rock scraped off a descending plate and piled up at a convergent boundary.
A volcanic island arc formed by subduction.
A mountain range formed by the collision of two continental plates.
Which of the following is a primary cause of earthquakes?

The accumulation of sediment in ocean basins.
The erosion of mountain ranges.
What is a terrane, and how does it relate to plate tectonics?
A large, stable block of the Earth's crust.
A fragment of crustal material formed on, or broken off from, one tectonic plate and accreted to another.

How do divergent plate boundaries contribute to the formation of new oceanic crust?
By the subduction of oceanic plates beneath continental plates.
By the upwelling of magma from the mantle, creating new crust as plates move apart.
By the collision and folding of continental plates.
By the erosion of existing oceanic crust.
What is the primary effect of an earthquake on the Earth's surface?
The formation of new mountain ranges.
The creation of deep ocean trenches.
The shaking and displacement of the ground.
The cooling of the Earth's core.
Explain the role of subduction zones in the formation of volcanic mountain ranges.
Subduction zones cause the melting of the subducting plate, leading to magma formation and volcanic activity.
Subduction zones lead to the erosion of mountain ranges by ocean currents.
Subduction zones create new oceanic crust through sea-floor spreading.
Subduction zones result in the cooling and solidification of magma beneath the Earth's surface.
Which of the following best describes a convergent plate boundary?
A boundary where two plates slide past each other horizontally.
A boundary where two plates move away from each other.
A boundary where two plates move towards each other and collide.
A boundary where one plate is stationary and the other moves over it.
Discuss the relationship between volcanic activity and the formation of island arcs.
Island arcs form from the accumulation of sediment at divergent boundaries.
Island arcs are formed by volcanic activity at convergent boundaries where oceanic plates subduct.
Island arcs are created by the erosion of continental landmasses.
Island arcs result from the cooling and solidification of magma at transform boundaries.
What is the significance of transform boundaries in the context of earthquakes?
Transform boundaries are areas where new crust is formed, leading to frequent earthquakes.
Transform boundaries are areas where plates slide past each other, often causing earthquakes.
Transform boundaries are areas where plates converge, leading to the formation of mountain ranges.
Transform boundaries are areas where plates diverge, resulting in volcanic activity.
Analyze the impact of terrane accretion on the geological features of a continent.
Terrane accretion leads to the formation of deep ocean trenches along continental margins.
Terrane accretion results in the growth and modification of continental crust, creating diverse geological features.
