Explanation:

• Secondary microplastics are formed through the degradation of larger plastic items like bottles, fishing nets and plastic bags. This occurs through exposure to the environment, like radiation from the sun, wind and ocean waves.
• When snow travels in the atmosphere, it binds itself to airborne particles and pollutants, which are then deposited on Earth’s surfaces. This phenomenon is called “scavenging”. Hence, this is a significant way in which microplastics are able to travel and further pollute land and water.

Hence both statements are correct.
