Final Exam

Front

What generates electric currents in the outer core of the Earth?

Back

The flow of liquid iron.

Front

What is created by the Coriolis force in the Earth's outer core?

Back

Earth's magnetic field.

Front

If Q = -1045, what does this indicate about the reaction's heat exchange?

Back

The reaction is releasing heat.

Front

What happens to material that subducts into the mantle?

Back

It gets recycled in the mantle through convection currents.

Front

On which side of the chemical equation is the fat molecule found?

Back

Reactants.

Front

What is the reaction: NaHCO3 + 129 kJ -> Na2CO3 + H2O + CO2 indicating about heat?

Back

The reaction is absorbing heat.

Front

Define 'subduction' in geological terms.

Back

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

Front

What is the role of conduction currents in the mantle?

Back

Conduction currents transfer heat through the mantle, affecting material properties.

Front

Explain the difference between exothermic and endothermic reactions.

Back

Exothermic reactions release heat, while endothermic reactions absorb heat.

Front

What is the significance of the Coriolis effect in meteorology?

Back

The Coriolis effect influences wind patterns and ocean currents due to Earth's rotation.
