The Sun: Energy and Lifespan Flashcard

Front

What is the primary process that produces energy in the sun’s core?

Back

Nuclear fusion is the process that produces energy in the sun's core by fusing hydrogen atoms into helium.

Front

How does the energy produced by nuclear fusion in the sun’s core travel to Earth?

Back

The energy travels to Earth as electromagnetic radiation, which includes visible light, ultraviolet light, and infrared radiation.

Front

What is at the center of the Solar System?

Back

The Sun is at the center of our solar system, and all planets, including Earth, orbit around it.

Front

Which element is primarily fused in the sun’s core to produce energy?

Back

Hydrogen is the primary element that is fused in the sun's core to produce energy.

Front

What form of energy from the sun eventually reaches Earth?

Back

Radiation is the form of energy from the sun that eventually reaches Earth.

Front

What is nuclear fusion?

Back

Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing energy.

Front

What is the role of gravity in the solar system?

Back

Gravity keeps the planets in orbit around the Sun and holds the solar system together.

Front

What is electromagnetic radiation?

Back

Electromagnetic radiation is energy that travels through space in the form of waves, including visible light, radio waves, and X-rays.

Front

What is the temperature at the core of the Sun?

Back

The temperature at the core of the Sun is approximately 15 million degrees Celsius.

Front

What is the life cycle of a star like the Sun?

Back

The life cycle of a star like the Sun includes stages: nebula, main sequence, red giant, and eventually a white dwarf.
