In this part :
To understand water, hydrologists must study how the hydrosphere interacts with the other spheres on Earth such as :
- How water runs across the land (geosphere).
- How water affects living organisms (biosphere).
- What happens to water in air (atmosphere).

Microplastics
▌Microplastics are plastic pieces whose lengths are less than 5 millimeters.
▌Microplastics are formed when plastic waste is broken down into small particles by wind, sunlight and wave action at sea.
▌Microplastics are found everywhere on Earth, from the highest place on land to the deepest part of the ocean.
▌Hydrologists are concerned about the amount of plastic pollution found in the hydrosphere.
▌Microplastics found in aquatic ecosystems are more harmful to aquatic organisms than large plastic waste, where aquatic organisms cannot differentiate between their real food and plastic waste, so they can eat these pieces of plastic and get harmed.

Analyzing pollution
▌A group of scientists in India wanted to learn more about the effects of microplastics on the environment.
▌These scientists took samples of the water and the soil of a polluted river and they
found that microplastics were present in the water and the soil of that river.
▌After analyzing these samples, scientists found that most of these microplastics
were from decayed plastic carry bags, packing materials, and fishing lines.


بالتوفيق
