Which of the following protects earths atmosphere from solar wind

The Earth's magnetic field primarily protects its atmosphere from solar wind.

The Earth's atmosphere is protected from solar wind by its magnetic field. The magnetic field acts as a shield, deflecting and diverting most of the solar wind particles away from the Earth. Additionally, the atmosphere itself absorbs some of the energy from the solar wind, reducing its impact on the planet.

The Earth's atmosphere is protected from solar wind by its magnetic field. This magnetic field is generated by the spinning of the Earth's core, which creates a magnetic bubble called the magnetosphere around the planet. The magnetosphere stretches out into space on the side facing the Sun and acts as a shield, deflecting and trapping most of the charged particles coming from the Sun, including the solar wind.

To find this answer, you can refer to scientific research articles, textbooks, or educational websites that cover the topic of the Earth's magnetic field and its interaction with the solar wind. NASA's website is a reliable source of information about the Earth's magnetic field and its role in protecting our atmosphere from solar wind.
