Science 8 Earth's interior and plate tectonics review

Front

What technology is used to map the seafloor?

Back

Sound waves are used to map the seafloor.

Front

What type of tectonic plate boundary is indicated by ridges along the seafloor?

Back

Divergent boundary.

Front

What is the composition of the Earth's inner core?

Back

The Earth's inner core is a solid of mostly iron.

Front

What type of boundary interaction formed the Himalayan mountain range?

Back

Convergent boundary interaction.

Front

What is the interaction between the Juan de Fuca plate and the North American plate?

Back

Convergent interaction.

Front

Define 'plate tectonics'.

Back

Plate tectonics is the theory that explains the movement of the Earth's lithosphere which is divided into tectonic plates.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, often creating new crust.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, leading to the formation of mountains or subduction zones.

Front

What is a transform boundary?

Back

A transform boundary is where two tectonic plates slide past each other horizontally.

Front

What is subduction?

Back

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