What is the Ring of Fire?

Back

The Ring of Fire is a horseshoe-shaped zone in the Pacific Ocean basin known for its high volcanic and seismic activity, primarily due to subduction zones.

Front

What causes volcanoes to form at subduction zones?

Back

At subduction zones, one tectonic plate is forced under another, leading to melting of the subducted plate and the formation of magma, which can result in volcanic eruptions.

Front

What is the Theory of Plate Tectonics?

Back

The Theory of Plate Tectonics explains the movement of Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What evidence supports the Theory of Plate Tectonics?

Back

Evidence includes the fit of continents, fossil similarities across continents, glacial deposits in warm areas, and the distribution of earthquakes and volcanoes.

Front

What are converging tectonic plates?

Back

Converging tectonic plates are plates that move towards each other, often causing one plate to be forced beneath another, leading to mountain formation or volcanic activity.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates pull apart.

Front

Who proposed the theory of continental drift?

Back

Alfred Wegener proposed the theory of continental drift, which suggests that continents were once joined and have since drifted apart.

Front

What is a transform boundary?

Back

A transform boundary is a type of tectonic plate boundary where two plates slide past each other horizontally, often causing earthquakes.

Front

What geological features are formed by diverging tectonic plates?

Back

Diverging tectonic plates can create mid-ocean ridges, rift valleys, and new oceanic crust.

What is the significance of the oldest rocks found on Earth?

Back

The oldest rocks provide insights into the early history of the Earth and the processes that shaped its surface.
