Solar Energy

What is nuclear fusion in the sun?

• Process in which hydrogen nuclei combine to form helium

• Process in which oxygen nuclei combine to form carbon

• Process in which uranium nuclei combine to form plutonium

• Process in which iron nuclei combine to form nickel

How is energy transferred in the sun?

• Through nuclear fusion reactions

• Through chemical combustion reactions

• Through the generation of electricity from sunlight

• Through the transmission of heat from the core

What is solar radiation?

• Earth emitted by the sun in the form of electromagnetic waves

• Wind emitted by the sun in the form of electromagnetic waves

• Water emitted by the sun in the form of electromagnetic waves

• Energy emitted by the sun in the form of electromagnetic waves

What is the main process that generates energy in the sun?

• Solar energy

• Hydrogen combustion

How is energy transferred from the sun's core to the surface?

• Friction and convection

• Fusion and convection

• Gravitation and radiation

• Radiation and convection

What types of radiation does the sun emit?

• X-rays, gamma rays, alpha rays

• Laser rays, plasma rays, particle rays

• Radio waves, microwaves, cosmic rays

• Visible light, ultraviolet and infrared rays

What is the role of solar radiation on Earth?

• Cause global cooling

• Provide energy through photosynthesis and heating of the atmosphere and oceans.

• Increase the acidity of the oceans

• Generate static electricity in the atmosphere

What elements participate in nuclear fusion in the sun?
