High School Earth Science/Water on Earth 1 Earth's surface is mostly water covered. Most of that water is in our oceans, leaving only 3% freshwater. 2  Water exists on Earth in all three phases: solid, liquid, and gas.  The water cycle moves water from the hydrosphere to the atmosphere to the land and back again.

- Water is also found in the atmosphere, underground, in. snow, ice, seas and oceans. It is in constant motion and recycles itself through the Water Cycle. Most of the earth’s water is salty or permanently frozen. 95.1% of water on earth is estimated. to be salt water. Fresh water total only 4.9% of all water on earth. Fresh water is found in. ice, lakes, rivers, streams and underground. 0.01% of earth’s water is found in rivers and. lakes. Humans need water to live. The most common sources of drinking water come from. groundwater (wells), lakes, rivers and streams.

Introduction Oceans, which are the largest source of surface water, comprise approximately 97 percent of the Earth's surface water. However, since the oceans have high salinity, the water is not useful as drinking water. Efforts have been made to remove the salt from the water (desalination), but this is a very costly endeavor.

Summary of the Water Cycle ). Studies have revealed that evaporation—the process by which water changes from a liquid to a gas—from oceans, seas, and other bodies of water (lakes, rivers, streams) provides nearly 90% of the moisture in our atmosphere. Most of the remaining 10% found in the atmosphere is released by plants through transpiration.n the cool air, water vapor is more likely to condense from a gas to a liquid to form cloud droplets. Cloud droplets can grow and produce precipitation (including rain, snow, sleet, freezing rain, and hail), which is the primary mechanism for transporting water from the atmosphere back to the Earth’s surface.

Planet Profile 71 Percent of the Earth's surface is covered with water. Earth is the only planet on which water can exist in liquid form on the surface (though there may be liquid ethane or methane on Titan's surface and liquid water beneath the surface of Europa). Liquid water is, of course, essential for life as we know it.

Earth Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. About 71% of Earth's surface is covered with water, mostly by its oceans. The remaining 29% is land consisting of continents and islands that together have many lakes, rivers and other sources of water that contribute to the hydrosphere.

Nature An ocean (from Greek , okeanos Oceanus) is a major body of saline water. The ocean covers 71 percent of the Earth's surface and contains 97 percent of the planet's water, yet more than 95 percent of the underwater world remains unexplored. The ocean and lakes play an integral role in many of the Earth's systems including climate and weather.

The water cycle The water cycle encompasses a number of processes that circulate water through the Earth’s subsystems. Water evaporates from within soils and through vegetation22 and from bodies of water (such as rivers, lakes and oceans). This evaporated water accumulates as water vapour33 in clouds and returns to the Earth as rain or snow.

Introduction Most of the water used by humans comes from rivers. The visible bodies of water are referred to as surface water. The majority of fresh water is actually found underground as soil moisture and in aquifers. Groundwater can feed the streams, which is why a river can keep flowing even when there has been no precipitation. Humans can use both ground and surface water. Distribution of the water on Earth

Water cycle The water cycle, also known as the hydrological cycle or the hydrologic cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean
