Plate Tectonics and Succession

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced below the other, leading to mountain formation, earthquakes, and volcanic activity.

Front

What geologic feature is commonly found at a divergent boundary?

Back

A Mid-Ocean Ridge is commonly found at a divergent boundary, where two oceanic plates move apart, allowing magma to rise and create new oceanic crust.

Front

What evidence did Alfred Wegener use to support his theory of continental drift?

Back

Wegener used the shape of the continents, similar fossils found on separate continents, and tree fossils found in unusual locations as evidence for continental drift.

Front

What happens to Earth's tectonic activity if the mantle cools and solidifies?

Back

If Earth's mantle becomes cooler and solid, tectonic activity would cease, leading to a stable crust with no earthquakes or volcanic activity.

Front

What is the primary cause of tectonic plate movement?

Back

The primary cause of tectonic plate movement is the convection currents in the Earth's mantle, which are driven by heat from the Earth's core.

Front

What type of plate boundary is associated with earthquakes?

Back

Transform plate boundaries are associated with earthquakes, as they involve plates sliding past each other, causing friction and stress.

Front

What is a rift valley?

Back

A rift valley is a lowland region formed by the divergence of tectonic plates, characterized by steep walls and often filled with water.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another, leading to the formation of deep ocean trenches and volcanic arcs.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner and denser than continental crust, which is thicker and less dense, leading to different geological features.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally, causing earthquakes along faults.
