Water

H 2 OHOliquid water
The hydrosphere (from Greek ὕδωρ hydōr, "water" and σφαῖρα sphaira, "sphere" ) is the combined mass of water found on, under, and above the surface of a planet, minor planet or natural satellite.
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance, which is the main constituent of Earth's hydrosphere, and the fluids of most living organisms.

Ocean

This includes water in liquid and frozen forms in groundwater, oceans, lakes and streams.
An ocean is a body of water that composes much of a planet's hydrosphere.

Earth

Earth's surfaceterrestrialworld
The total mass of Earth's hydrosphere is about 1.4 × 10 18 tonnes, which is about 0.023% of Earth's total mass. At any given time, about 20 × 10 12 tonnes of this is in the form of water vapor in the Earth's atmosphere (for practical purposes, 1 cubic meter of water weighs one tonne).
The remaining 29% is land consisting of continents and islands that together contain many lakes, rivers and other sources of water that contribute to the hydrosphere.

Water vapor

The total mass of Earth's hydrosphere is about 1.4 × 10 18 tonnes, which is about 0.023% of Earth's total mass. At any given time, about 20 × 10 12 tonnes of this is in the form of water vapor in the Earth's atmosphere (for practical purposes, 1 cubic meter of water weighs one tonne).
It is one state of water within the hydrosphere.

Water cycle

The water cycle refers to the transfer of water from one state or reservoir to another.
The water cycle describes the processes that drive the movement of water throughout the hydrosphere.

Climate system

Earth's climate arises from the interaction of five major climate system components: the atmosphere (air), the hydrosphere (water), the cryosphere (ice and permafrost), the lithosphere (earth's upper rocky layer) and the biosphere (living things).

Biosphere

ecospherebiosphericenvironment
By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere.

Cryosphere

Thus, there is a wide overlap with the hydrosphere.

Pedosphere

It exists at the interface of the lithosphere, atmosphere, hydrosphere and biosphere.

Lithosphere

The uppermost part of the lithosphere that chemically reacts to the atmosphere, hydrosphere, and biosphere through the soil forming process is called the pedosphere.

Atmosphere of Earth
