Unit 7 Bell Work Day 4

Front

What is Pangaea?

Back

Pangaea is the name of the supercontinent that existed during the late Paleozoic and early Mesozoic eras, where all continents were once joined together.

Front

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

Back

Wegener found similar rocks of the same type, age, and color on multiple continents, suggesting they were once connected.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What geologic feature is commonly found at a divergent boundary between oceanic crust?

Back

A Mid-Ocean Ridge is commonly found at a divergent boundary between two pieces of oceanic crust.

Front

What is the Ring of Fire?

Back

The Ring of Fire is an area around the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur due to tectonic plate boundaries.

Front

What geologic feature is formed at a divergent boundary between continental crust?

Back

A Rift Valley is formed at a divergent boundary between two pieces of continental crust.

Front

What type of plate boundary is characterized by plates sliding past each other?

Back

A transform boundary is characterized by tectonic plates sliding past one another.

Front

What is the significance of the Mid-Ocean Ridge?

Back

The Mid-Ocean Ridge is significant as it is the longest mountain range in the world and is a site of seafloor spreading.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, two tectonic plates move towards each other, which can result in one plate being forced below another, leading to subduction.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another plate and sinks into the mantle.
