hydrosphere, discontinuous layer of water at or near Earth’s surface. It includes all liquid and frozen surface waters, groundwater held in soil and rock, and atmospheric water vapour. Water is the most abundant substance at the surface of Earth.
The hydrosphere (from Ancient Greek ὕδωρ (húdōr) 'water' and σφαῖρα (sphaîra) 'sphere') [1] [2] is the combined mass of water found on, under, and above the surface of a planet, minor planet, or natural satellite.
The hydrosphere refers collectively to all forms of water on Earth. It includes surface water bodies like rivers, oceans, lakes, and ponds, groundwater, water vapor (clouds and fog) in the atmosphere, and ice.
The meaning of HYDROSPHERE is the aqueous vapor of the atmosphere; broadly : the aqueous envelope of the earth including bodies of water and aqueous vapor in the atmosphere.
A hydrosphere is the total amount of water on a planet. The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes, and rivers.
hydrosphere / hī ′ drə-sfîr′ / All of the Earth's water, including surface water (water in oceans, lakes, and rivers), groundwater (water in soil and beneath the Earth's surface), snowcover, ice, and water in the atmosphere, including water vapor.
all of the water, ice, and water vapor at or near the surface of the earth, such as the seas, clouds, and the water in and under the ground: The hydrosphere covers most of the surface of the earth as seas. Oceans are a principal component of the hydrosphere. See also. asthenosphere. the atmosphere.
All of the water on Earth, including freshwater and the oceans, makes up the hydrosphere. Most of this water, a whopping 97%, is found in Earth’s oceans. Oceans and seas cover more than 70% of Earth’s surface, giving our planet its distinctive blue color when viewed from space.
The hydrosphere is the sum of Earth’s water, in the ocean, the ground, on the surface, and in the air. Approximately 71 percent of Earth’s surface is covered in water. Of all of that water, only about three percent is freshwater. An even smaller amount can be used as drinking water.
What is the Hydrosphere? The hydrosphere is a vast and dynamic system of all things watery. In fact, the hydrosphere covers about 71% of our planet’s surface. From the deepest oceans to the tiniest droplets in clouds, the hydrosphere supports life as we know it. But it does more than that…
