Water covers approximately 71% of the Earth's surface in oceans, lakes, and rivers. Water moves into the oceans from rivers and streams. What is the term for the process of water moving out of the ocean?

Where does most of Earth's precipitation and evaporation occur?

According to the United States Geological Survey, “About 71 percent of the Earth’s surface is water-covered, and the oceans hold about 96.5 percent of all Earth’s water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog. The vast majority of water on the Earth’s surface, over 96 percent, is saline water in the oceans. The freshwater resources, such as water falling from the skies and moving into streams, rivers, lakes, and groundwater, provide people with the water they need every day to live. Even though you may only notice water on the Earth’s surface, there is much more freshwater stored in the ground than there is in liquid form on the surface. Some of the water you see flowing in rivers comes from the seepage of groundwater into river beds. Water from precipitation continually seeps into the ground to recharge aquifers, while at the same time, water in the ground continually recharges rivers through seepage. Water is never sitting still. Thanks to the water cycle, our planet’s water supply is constantly moving from one place to another and from one form to another.” Overall there are said to be 326 million trillion gallons of water on Earth, and only 3% is fresh water.

Which answer choice best describes the amounts of water on Earth?

True or False: The total amount of water on Earth does not change.

Where is the majority of water on Earth found?

About 71% of Earth's surface is covered by water and of that 97% is saltwater located in oceans. The water in the ocean only contains about three to four percent salt. If you wanted to replicate this at home, you could mix six ounces of water with a teaspoon of salt, and it would be the same salinity as ocean water. Oceans become saltier over time as water evaporates, and small amounts of salt are carried to the oceans by rivers.

Select which statement is true.

A majority of the water on Earth is ________ and ___________.

One-third of Earth's freshwater is located underground. This is less than the amount found in glaciers but more than the amount found in lakes and rivers.

Which source of freshwater has the smallest quantity of water?

Which stages of the water cycle add water directly to the oceans?

True or False: Oceans of freshwater cover much of Earth’s surface. Freshwater is water that contains little or no salt. Most of Earth’s saltwater is frozen in ice caps and glaciers.
