Question

Select all the correct statements concerning the link between the solar cycle and Earth.

a) The solar cycle affects Earth's climate.
b) The solar cycle influences radio communication.
c) The solar cycle impacts Earth's orbit.
d) The solar cycle affects the length of Earth's day.

Answer 1

The solar cycle affects Earth's climate, influences radio communication, and affects the length of Earth's day.

Step-by-step explanation:

The correct statements concerning the link between the solar cycle and Earth are:

1. The solar cycle affects Earth's climate.
2. The solar cycle influences radio communication.
3. The solar cycle affects the length of Earth's day.

The solar cycle refers to the natural 11-year cycle of small ups and downs in the intensity of the sunlight emitted by the sun. These variations in solar activity can have significant effects on Earth's climate, such as changes in temperature and weather patterns.

Additionally, the variations in solar activity can impact radio communication by affecting the ionosphere, which plays a crucial role in the propagation of radio waves. They can also affect the length of Earth's day through interactions with Earth's magnetic field.
