- When we think of water, we think of rain, lakes and rivers. because they are parts of our daily lives. 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.

- Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, 599 mM) This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+.

Water distribution on Earth Water is distributed across earth. Most water in the Earth's atmosphere and crust comes from the world ocean's saline seawater, while freshwater accounts for only 2.5% of the total. Because the oceans that cover roughly 78% of the area of the Earth reflect blue light, the Earth appears blue from space, and is often referred to as the blue planet and the Pale Blue Dot. An estimated 1.5 to 11 times the amount of water in the oceans may be found hundreds of miles deep within the Earth's interior, a

How Much Water Is on Earth? How much water is that? It's roughly 326 million cubic miles (1.332 billion cubic kilometers), according to a recent study from the U.S. Geological Survey. Some 72 percent of Earth is covered in water, but 97 percent of that is salty ocean water and not suitable for drinking.There's not a lot of water on Earth at all, said David Gallo, an oceanographer at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts.Oceans create a water layer spanning 15,000 miles (24,000 kilometers) across the planet at an average depth of more than 2 miles (3.2 km).If you poured all of the world's water on the United States and could contain it, you'd create a lake 90 miles (145 km) deep.ceans create a water layer spanning 15,000 miles (24,000 kilometers) across the planet at an average depth of more than 2 miles (3.2 km).

Water distribution on Earth Distribution of saline and fresh water[edit] The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles), with 97.5% being salt water and 2.5% being fresh water. Of the fresh water, only 0.3% is in liquid form on the surface.

- The saltwater in Earth's oceans has an average salinity of 3.5 percent, and freshwater in Earth's lakes and streams has less than 0.5 percent. Freshwater is a basic need for all animals, including humans, which makes the discussion of water one of the most important in this course.

Seawater Seawater, or salt water, is water from a sea or ocean. On average, seawater in the world's oceans has a salinity of about 3.5% (35 g/L, or 600 mM). This means that every kilogram (roughly one litre by volume) of seawater has approximately 35 grams (1.2 oz) of dissolved salts (predominantly sodium (Na+.

How much water is there on Earth? ­The oceans are huge. About 70 percent of the planet is covered in ocean, and the average depth of the ocean is several thousand feet (about 1,000 meters). Ninety-eight percent of the water on the planet is in the oceans, and therefore is unusable for drinking because of the salt.

Environmental Science: Earth's Water The table describes the main locations of water on Earth. Notice that about 98 percent of Earth's water is saltwater. The remaining 2 percent is freshwater, but the majority of that percentage is found in the polar ice caps and glaciers, which is not readily available to us. The only freshwater that can be readily used by animals and humans is the freshwater found in rivers and groundwater.

How much water is on Earth? It’s also in living things. Your body is made up mostly of water. Water covers 71 percent of Earth’s surface. And almost all of it—96.5 percent—is salt water. Salt water has different kinds of salt in it, but it mostly has sodium chloride, the same salt we add to our food. Just 3.5 percent of the water on Earth is fresh water we can drink. And most of that fresh water, 68 percent, is trapped in ice and glaciers. A third of the fresh water is in the ground. We call it groundwater. The last two percent of fresh water is in the rivers, lakes, and streams.

What percent of Earth is water? In simplest terms, water makes up about 71% of the Earth’s surface, while the other 29% consists of continents and islands. To break the numbers down, 96.5% of all the Earth’s water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact. If you could melt all that ice, and the Earth’s surface was perfectly smooth, the sea levels would rise to an altitude of 2.7 km.

Water distribution on Earth Water distribution on Earth - Distribution of saline and fresh water. 1  The total volume of water on Earth is estimated at 1.386 billion km³ (333 million cubic miles), with 97.5% being salt water and 2.5% being fresh water. 2  The total volume of water in rivers is estimated at 2,120 km³ (510 cubic miles), or 2% of the surface fresh water on Earth. Rivers and basins are often compared not according to their static volume, but to their flow of water, or surface runoff.

Why is the Ocean Salty? Together, they make up over 90 percent of all dissolved ions in the ocean. Sodium and Chloride are 'salty.'. The concentration of salt in seawater (salinity) is about 35 parts per thousand. Stated in another way, about 3.5 percent of the weight of seawater comes from the dissolved salts; in a cubic mile of seawater, the weight of the salt (in the form of sodium chloride) would be about 120 million tons.

- Why are the Oceans Salty? As water flows in rivers, it picks up small amounts of mineral salts from the rocks and soil of the river beds. This very-slightly salty water flows into the oceans and seas. The water in the oceans only leaves by evaporating (and the freezing of polar ice), but the salt remains dissolved in the ocean - it does not evaporate. So the remaining water gets saltier and saltier as time passes.

INVASIVE PLANT SRECIES IN NORTHLANDPLANTS NOT RECOMENDED FOR PLANTING IN WHANGAREI & DISTRICTS - Weedbusters Northland in conjunction with The Whangarei District Council; Whangarei Regional Council; Department of Conservation; Far North Council & Kaipara DistrictCouncil, advise people not to plant certain species of plant in Whangarei. There is a colour book available from Council Offices free of charge that list these plants. 'PLANT ME INSTEAD' has excellent colour photography and text.  (Picture above shows Morning Glory - Ipomoea - almost killing a Puriri tree). Cortaderia selloana. Cortaderia selloana, commonly known as pampas grass, is a flowering plant native to southern South America, including the Pampas region after which it is named. There are around 25 species in the genus Cortaderia. It is a tall grass, growing in dense tussocks that can reach a height of 3 m (10 ft). The leaves are long and slender, 1–2 m (3 ft 3 in–6 ft 7 in) long, and 1 cm broad, with very sharp edges.

Summary of the Water Cycle There is not really much fresh ware on Earth. 1.74% of all Earth's water is in this frozen form as ice caps, glaciers and snow. Only 0.75% of Earth's water is liquid water and potentially accessible as fresh water in ground water, lakes, streams and swamps. Long Answer: About 97.5% of water on Earth is salt water and 2.5% fresh water. All of the oceans are salt water and the oceans represent more than 96% of all water on Earth. Of the 2.5% fresh water, only 0.3% is in liquid form on the surface. Most of the rest is frozen or underground. Less than .01 % of all water is in lakes and rivers.

Amount of fresh water on earth? Out of all the water on Earth, saline water in oceans, seas and saline groundwater make up about 97% of it. Only 2.5–2.75% is fresh water, including 1.75–2% frozen in glaciers, ice and snow, 0.5–0.75% as fresh groundwater and soil moisture, and less than 0.01% of it as surface water in lakes, swamps and rivers.

Why is the sea water salty? The Baltic Sea has less salinity with 5 to 15 parts of salts per thousand pounds of ocean water. The North Atlantic Ocean is the saltiest with 37.9 pounds of salt per thousand pounds of ocean water. (Also know about dead sea) William Dittmar, a scientist collected several samples of ocean water to detect the salinity.

Why canât I waste water? Even though it seems like there’s a lot of water on our planet, not all of the water on Earth is actually “usable.” Over 97% of the Earth’s water is salty and not drinkable (like ocean water), and of the remaining freshwater (which makes up less than 3%), only a small percentage can be used.
