AICE Earth Processes: Unit 2.1

Front

What occurs at an oceanic-continental convergent boundary?

Back

The oceanic crust is subducted below the continental crust.

Front

What are the primary causes of tsunamis?

Back

Tsunamis are typically generated by underwater earthquakes or volcanic eruptions.

Front

What elements are responsible for the black smoke emitted from hydrothermal vents?

Back

Iron, copper, and zinc.

Front

What are the two types of Earth's crust?

Back

Continental crust and oceanic crust.

Front

Where do hydrothermal vent ecosystems obtain their hot water and chemicals?

Back

From fractures in the oceanic crust where water meets magma.

Front

What is subduction in the context of tectonic plates?

Back

Subduction is the process where one tectonic plate moves under another and is forced into the mantle.

Front

What is the role of hydrothermal vents in ocean ecosystems?

Back

Hydrothermal vents provide nutrients and energy for unique ecosystems, supporting organisms that rely on chemosynthesis.

Front

How do oceanic and continental crust differ in density?

Back

Oceanic crust is denser than continental crust.

Front

What geological features are commonly formed at convergent boundaries?

Back

Mountain ranges, deep ocean trenches, and volcanic arcs.

Front

What is the significance of the Ring of Fire?

Back

The Ring of Fire is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur, due to tectonic plate boundaries.
