Earth Science Final Exam Review

Energy is released from the sun and ultimately reaches Earth. Analyze the graph of solar irradiance.

Which explanation could describe why the amount of energy that reaches Earth is not consistent?

• The photons generated in the core of the sun are released every 11 years.

• Sunspots release energy in an 11-year cycle because of the magnetic field of the sun.

• The energy released from the process of fusion in the core of the sun takes 11 years to rise to the surface.

• The change of winds in the coronal layer of the sun sends energy from the sun to Earth in 11-year cycles.

Put the steps that energy takes from its formation in the sun to its transfer to Earth’s atmosphere in order...

Which step comes after "Fusion in the core produces helium and energy."

• Energy is released to the photosphere.

• Radiation cycles through the convection layer.

• Energy in the form of electromagnetic waves travels through the radiative zone.

• Energy escapes as light, solar wind, and other wavelengths of energy.

• Energy is absorbed by Earth’s atmosphere.
