Solar Cycle

It is due to the changes in the magnetic field structures in the solar corona.

What is the solar cycle?

• A nearly 11-year cycle of changes in the Sun's activity, including variations in the number of sunspots on its surface.

• A disturbance in the Sun's magnetic field that causes it to emit more radiation.

• A dark, cooler area on the Sun's surface that arises due to disturbances in its magnetic field.

• A phenomenon that occurs when the Sun's magnetic field flips.

What is the evidence provided in the text to support the claim that the solar cycle has an impact on Earth's climate?

• During the solar cycle, the Sun's ultraviolet (UV) radiation increases, triggering chemical reactions in the atmosphere that affect temperatures and winds.

• The solar cycle affects space weather and can impact technologies on Earth, such as satellites and GPS systems.

• Sunspots are dark, cooler areas on the Sun that arise due to disturbances in its magnetic field.

• Over 11 years, the poles of the sun's magnetic field switch position, known as a solar cycle.

In what ways do you see the effects of the solar cycle in your environment?

• Increased radiation exposure and geomagnetic storms that interfere with communication systems.

• Influencing temperatures and winds through chemical reactions in the atmosphere.

• Heating the stratosphere near the equator, affecting the winds that circulate the globe.

• Generating high-energy particles that destroy ozone in the stratosphere.

How do scientists track the solar cycle and what happens when a new cycle begins?

• A nearly 11-year cycle of changes in the Sun's activity, including variations in the number of sunspots on its surface.

• A disturbance in the Sun's magnetic field that causes it to emit more radiation.

• A dark, cooler area on the Sun's surface that arises due to disturbances in its magnetic field.

• A phenomenon that occurs when the Sun's magnetic field flips.

How does the solar cycle affect Earth's climate and why is it important to study its relationship to climate change?

• During the solar cycle, the Sun's ultraviolet (UV) radiation increases, triggering chemical reactions in the atmosphere that affect temperatures and winds.

• The solar cycle affects space weather and can impact technologies on Earth, such as satellites and GPS systems.

• Sunspots are dark, cooler areas on the Sun that arise due to disturbances in its magnetic field.

• Over 11 years, the poles of the sun's magnetic field switch position, known as a solar cycle.
