How The Elements of Periodic Table used in our daily life? Chemistry plays a great role in our daily life. Everything in our lives from material to life involves chemistry.

depletion; space exploration contributes far more than what is lost during takeoff. Space travel has been proven to benefit Earth’s environment by monitoring water quality, understanding the Earth’s weather patterns, and improving the lifespan of plants. Water on Earth makes up to 70 percent of the planet, but only 2.5 percent of water is available for humans to drink. This makes water monitoring from space crucial for human survival.
