The correct answer is A. oceans and seas.<\/p>\n
Oceans and seas cover about 71% of the Earth’s surface, and contain about 97% of the Earth’s water. Groundwater, rivers and streams cover about 2.5% of the Earth’s water, glaciers and ice sheets cover about 1.7% of the Earth’s water, and freshwater lakes and water vapours cover about 0.03% of the Earth’s water.<\/p>\n
Oceans and seas are the largest reservoirs of water on Earth. They are home to a vast array of marine life, and play an important role in the Earth’s climate system. Groundwater is water that is stored underground in aquifers. It is a vital source of water for drinking, irrigation, and industry. Rivers and streams are bodies of water that flow over the surface of the Earth. They are important for transportation, recreation, and the environment. Glaciers and ice sheets are large masses of ice that form on land. They are a major source of fresh water, and play an important role in the Earth’s climate system. Freshwater lakes are bodies of water that are not salty. They are important for drinking, irrigation, and recreation. Water vapour is water that is in the form of a gas. It is a major component of the Earth’s atmosphere, and plays an important role in the Earth’s climate system.<\/p>\n","protected":false},"excerpt":{"rendered":"
