The importance of Earth's magnetic field for sustaining life on our planet primarily includes the following options:
1. **Protects Earth from cosmic radiation that would be harmful to life**: The magnetic field helps shield the planet from harmful cosmic rays and solar radiation, which can damage living organisms and disrupt biological processes.
2. **It prevents the atmosphere from getting blown away by solar winds**: The magnetic field acts as a barrier against solar winds, which are streams of charged particles emitted by the sun. Without the magnetic field, these particles could strip away the atmosphere, making it difficult for life to survive.
The other options, such as making the Earth orbit the sun and being the reason for the Earth's tilt (which creates the seasons), are not directly related to the magnetic field. Therefore, the correct choices are the first and fourth options.
