1. Hydrosphere

   The hydrosphere (from Ancient Greek ὕδωρ (húdōr) 'water', and σφαῖρα (sphaîra) 'sphere') is the combined mass of water found on, under, and above the surface of a planet, minor planet, or natural satellite. Although Earth's hydrosphere has been around for about 4 billion years, it continues to change in shape. This is caused by seafloor spreading and continental drift, which rearranges the land and ocean.It has been estimated that there are 1.386 billion cubic kilometres (333 million cubic miles) of water on Earth. This includes water in gaseous, liquid and frozen forms as soil moisture, groundwater and permafrost in the Earth's crust (to a depth of 2 km); oceans and seas, lakes, rivers and streams, wetlands, glaciers, ice and snow cover on Earth's surface; vapour, droplets and crystals in the air; and part of living plants, animals and unicellular organisms of the biosphere. Saltwater accounts for 97.5% of this amount, whereas fresh water accounts for only 2.5%. Of this fresh water, 68.9% is in the form of ice and permanent snow cover in the Arctic, the Antarctic and mountain glaciers; 30.8% is in the form of fresh groundwater; and only 0.3% of the fresh water on Earth is in easily accessible lakes, reservoirs and river systems.The total mass of Earth's hydrosphere is about 1.4 × 1018 tonnes, which is about 0.023% of Earth's total mass. At any given time, about 2 × 1013 tonnes of this is in the form of water vapor in the Earth's atmosphere (for practical purposes, 1 cubic metre of water weighs 1 tonne). Approximately 71% of Earth's surface, an area of some 361 million square kilometres (139.5 million square miles), is covered by ocean. The average salinity of Earth's oceans is about 35 grams of salt per kilogram of sea water (3.5%).

1. hydrosphere

   The hydrosphere is the combined mass of water found on, under, and above the surface of the planet. It includes water in various forms such as liquid, vapor, and ice, in locations like oceans, seas, rivers, lakes, groundwater, glaciers, polar ice caps, clouds, and water vapor in the atmosphere. The hydrosphere plays a crucial role in supporting life on earth.

1. Hydrosphere

   The hydrosphere in physical geography describes the combined mass of water found on, under, and over the surface of a planet. Igor Shiklomanov, the man selected by the United Nations to do its world inventory of water resources, estimated that there are 1386 million cubic kilometres of water on earth. This includes water in liquid and frozen forms in groundwaters, glaciers, oceans, lakes and streams. Saline water account for 97.5% of this amount. Fresh water accounts for only 2.5%. Of this fresh water 68.7% is in the "form of ice and permanent snow cover in the Antarctic, the Arctic, and in the mountainous regions. Next, 29.9% exists as fresh groundwaters. Only 0.26% of the total amount of fresh waters on the Earth are concentrated in lakes, reservoirs and river systems where they are most easily accessible for our economic needs and absolutely vital for water ecosystems." The total mass of the Earth's hydrosphere is about 1.4 × 1018 tonnes, which is about 0.023% of the Earth's total mass. About 20 × 10¹² tonnes of this is in the Earth's atmosphere. Approximately 75% of the Earth's surface, an area of some 361 million square kilometers, is covered by ocean. The average salinity of the Earth's oceans is about 35 grams of salt per kilogram of sea water
