The Structure of Hydrosphere

This educational resource, developed for the NCDPI, explores the distribution and structure of the hydrosphere. It covers key water bodies like oceans, which hold 96.5% of the Earth's water, and freshwater sources, which only account for 3.5%. The curriculum explains various features of freshwater locations, including icebergs and glaciers, as well as the concepts of watersheds and river basins. Definitions of rivers, streams, lakes, and groundwater, including aquifers, are provided. A detailed overview of wetlands, their types, and functions is also included.

  1. The Structure of Hydrosphere Unit 3: Part 3 8th Grade Curriculum – Developed for NCDPI - 2008

  2. Oceans—96.5% of water found here Fresh water—3.5% of water found here Fresh water distribution: Ice: 1.762% Groundwater: 1.7% Surface Fresh Water: 0.014% Atmosphere and soil: 0.002% The Structure of Hydrosphere

  3. Understanding Where Your Water Is Located—Oceans and Ice • What bodies of water hold the largest amount of water? • Oceans—the largest bodies of water on Earth (contain salt water only) • What features house water as ice? • Icebergs: a large piece of freshwater ice floating in open waters • Glaciers: any large mass of ice that moves slowly over land • *permanent snow areas also “house” water as ice

  4. Fresh Water Locations—Surface Water • What is the difference between a watershed and a river basin? • Both terms describe land that drains into a river, stream or lake • River Basin: the term used to describe an area that drains into a large river • Watershed: the term used to describe an area that drains into a smaller river or stream

  5. Fresh Water Locations—River Basins and Watersheds • Larger river basins are made up of many interconnected watersheds • Example: Cape Fear and Neuse River Basins are made of many small watersheds • The water in a watershed runs to the lowest point—a river, stream, lake, or ocean

  6. Fresh Water Locations—Rivers, Streams, and Lakes • What is a river? • A large channel along which water is continually flowing down a slope—made of many streams that come together • What is a stream? • A small channel along which water is continually flowing down a slope—made of small gullies • What is a lake? • A body of water of considerable size contained on a body of land

  7. Fresh Water Locations--Groundwater • What is groundwater? • The water found in cracks and pores in sand, gravel and rocks below the earth’s surface • What is an aquifer? • A porous rock layer underground that is a reservoir for water

  8. Other Surface Waters • What is a wetland? • An area where the water table is at, near or above the land surface long enough during the year to support adapted plant growth • What are the types of wetlands? • Swamps, bogs, and marshes • Swamp: a wetland dominated by trees • Bogs: a wetland dominated by peat moss • Marshes: a wetland dominated by grasses
