Science, Chapter 6, Unit B Lesson 1 Where is Earth’s water?
2
Water Water covers ¾ of Earth’s surface 3 states Solid-ice Liquid-water Gas-water vapor
3
How many oceans are on earth? Although the oceans of the earth are all connected and truly one "World Ocean," most often the world is divided into four major "oceans" - the Pacific Ocean, Atlantic Ocean, Arctic Ocean, and the Indian Ocean. Some consider there to be five oceans - the fifth being an ocean surrounding Antarctica called the Antarctic Ocean or Southern Ocean.

Salty Water Ocean water is salty – Cannot drink – Sodium chloride (table salt) Water is made up of – Hydrogen – Oxygen H 2 O Ocean Water Mixture of: – Water – Dissolved solids (rocks and soils)
5
Fresh Water Found in: – Rivers – Lakes – Polar ice caps – Glaciers – underground Most of Earth’s fresh water is found here
6
Saltiness Not the same in all oceans Speed water turns to water vapor
7
Saltier – Warm, dry areas – Turns water to water vapor rapidly Less salty – Cool temperatures – Near North and South Poles – Turns water to water vapor slowly – Locations near rivers Heavy rainfall melting ice Add fresh water to oceans, Makes ocean water less salty
