How long does it take for energy from the Sun to reach Earth?

Back

It takes approximately 8 minutes for energy generated in the core of the Sun to reach Earth after leaving the Sun's surface.

Front

What are solar flares?

Back

Solar flares are sudden eruptions of energy on the Sun's surface that can cause disturbances in communications and power grids on Earth.

What is represented by A in the electromagnetic spectrum?

Back

A represents Radio waves.

Front

What is represented by B in the electromagnetic spectrum?

Back

B represents Infrared radiation.

Front

What is the primary source of energy for the Sun?

Back

The primary source of energy for the Sun is nuclear fusion.

Front

What are sunspots?

Back

Sunspots are temporary phenomena on the Sun's photosphere that appear as spots darker than the surrounding areas, caused by magnetic activity.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including gamma rays, X-rays, ultraviolet, visible light, infrared, microwaves, and radio waves.

Front

What is the significance of gamma rays in relation to the Sun?

Back

Gamma rays are high-energy radiation produced during nuclear fusion in the Sun's core.

Front

What role do solar winds play?

Back

Solar winds are streams of charged particles released from the Sun's atmosphere, affecting space weather and Earth's magnetosphere.
