IS2T3 Flashcard #1

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, typically occurring in solids.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas of a fluid rise and cooler areas sink.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, which can occur in a vacuum.

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 oceanic crust.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move towards each other, often leading to subduction or mountain formation.

Front

What is a transform boundary?

Back

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

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, generated by earthquakes or other geological activity.

Front

What does it mean for the Earth's layers to be heterogeneous?

Back

Heterogeneous means that the Earth's layers are composed of different materials and properties, leading to variations in density and composition.

Front

What is the significance of new oceanic crust formation?

Back

The formation of new oceanic crust at divergent boundaries is significant as it contributes to the process of seafloor spreading and plate tectonics.

Front

How does heat transfer from the core to the mantle?

Back

Heat transfer from the core to the mantle occurs primarily through conduction.
