4 a. Major Uses 1. Household 2. Agriculture-irrigation a. History 1.China 3000 BC irrigation by flooding rice paddies 2.Egypt, 2000 BC-Bucket device invented to raise water 3.Assyria, 700 BC-Stone aqueduct used by king for plantation 4.Mexico, 500 AD-raised plots with a canal 5.USA, 1870 windmills bring water 6.Israel, 2000-drip irrigation in the desert directly to roots

5 3. Industry-used to make products but can be recycled to cool machinery 4. Transportation-goods and boats 5. Recreation-boating, swimming, etc b. Water is used by living things to grow, reproduce and carry out life processes- like photosynthesis 66% of the human body is made up of water. At just 2% dehydration your performance decreases by around 20%. We should drink at least 1.5 litres of water a day. 66% of the human body is made up of water.

6 c. Groundwater is water that fills cracks and spaces in soil helping to bring nutrients to the soils and organisms in the soil.

7 1.Two-thirds of our planet is covered by water. 2.97% of the water is saltwater (dissolved salt and minerals). *3% is freshwater 3.The majority of freshwater is beyond our reach, locked into polar snow and ice (about 97%). 4.This leaves less than 1% for us to drink. 1.Two-thirds of our planet is covered by water. 2.97% of the water is saltwater (dissolved salt and minerals). *3% is freshwater 3.The majority of freshwater is beyond our reach, locked into polar snow and ice (about 97%). 4.This leaves less than 1% for us to drink.

9 Evaporation Evaporation occurs when the liquid form of water from bodies of water change into the gaseous form of water

10 Evapotranspiration is the water lost to the atmosphere from the ground surface. Evapotranspiration is the water lost to the atmosphere from the ground surface. The transpiration part is talking about evaporation of water from plant leaves. The transpiration part is talking about evaporation of water from plant leaves.

11 Sublimation is when a solid changes directly into a gas Sublimation is when a solid changes directly into a gas It is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water. It is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.

12 Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation is the change of water from its gaseous form (water vapor) into liquid water. This is crucial because it is responsible for the formation of clouds. This is crucial because it is responsible for the formation of clouds.

13 When cloud particles become too heavy to remain suspended in the air, they fall to the earth as precipitation. When cloud particles become too heavy to remain suspended in the air, they fall to the earth as precipitation.

14 divide which is a ridge or continuous point of high land into a drainage basin Snowmelt runoff is a major component in the water cycle. It runs off either side of a divide which is a ridge or continuous point of high land into a drainage basin

15 Infiltration Infiltration is when the water enters into the subsurface of soil and rocks. This becomes groundwater. Some soils are permeable-others are impermeable

16 As part of the water cycle, ground water is a major contributor to flow in many streams and rivers and has a strong influence on river and wetland habitats for plants and animals.

17 Most of the water in the ground comes from precipitation that infiltrates downward from the land surface Most of the water in the ground comes from precipitation that infiltrates downward from the land surface Large amounts of water are stored in the ground. In a region called the Aquifer. The upper layer of an aquifer is called a water table Large amounts of water are stored in the ground. In a region called the Aquifer. The upper layer of an aquifer is called a water table

18 Groundwater can be brought to the surface naturally by a spring, an artesian well or a geyser

19 As water moves through the water cycle, it is stored in various ways in the different spheres on Earth

20 Oceans, seas, and other bodies of water contain about 90% of the moisture in the atmosphere. Oceans, seas, and other bodies of water contain about 90% of the moisture in the atmosphere. Other 10%=plants, transpiration. Other 10%=plants, transpiration. 3,100 cubic miles of water. 3,100 cubic miles of water.

21 Includes all water on earth. Includes all water on earth million cubic kilometers of water on earth million cubic kilometers of water on earth. Not a single drop of water can be found anywhere else in the solar system. Not a single drop of water can be found anywhere else in the solar system.

22 The solid part of earth. The solid part of earth. Is composed of minerals and contains the groundwater. Is composed of minerals and contains the groundwater.

23 Is all living organisms. Is all living organisms. Covers the top 200 meters of oceans and seas. Covers the top 200 meters of oceans and seas.

24 Study your notes from the last 2 days. We will have a quiz or journal of some sort WITHOUT your notes! BE READY!!!!!
