Hydrogen ions diffuse from an area of high proton concentration to one of lower concentration.
There are four environments on Earth that are called spheres: hydrosphere, lithosphere, atmosphere, and biosphere.
<h3>Features associated with each of Earth's four spheres.</h3>
<h3>Hydrosphere </h3>
It is the set of all the water on the planet, including those that form clouds.
<h3>Lithosphere</h3>
The continuous part of our planet, made up of rocks and soil. The most superficial part is called the earth's crust.
<h3>Atmosphere</h3>
It is the gaseous sphere that surrounds our planet, composed mainly of gas oxygen and gas.
<h3>Biosphere </h3>
It is the part of our planet that can support life
<h3>Internal processes</h3>
The atmosphere and hydrosphere are the main regulators of the planet's climate. Without both, the temperature changes would be very sudden: at night it would drop to minus 150°C and during the day above 100°C, making life on Earth difficult.
With this information, we can conclude that the spheres of the earth, support life, and make the planet earth unique.
