1 Environmental Resources Unit A Problem Area 1Exploring Natural Resources
2 What is around you?Examine your surroundings, write down everything that is living or was once living.Think about what you are wearing, where you are sitting, what you are writing on, etc.What would life on earth be like without these items?
3 Learning Objectives Define and identify types of natural resources. Distinguish between renewable and nonrenewable resources.Explain the difference between inexhaustible and exhaustible resources.Explain the concept of interdependent relationships.
6 I. Types of Natural Resources A. Natural resources - Resources that occur naturally in natureB. The environment is the conditions that surround us
7 I. Types of Natural Resources C. Natural resources cannot be made by man, but man can help ensure their continued existenceD. People need many natural resources to liveE. Other natural resources are used to make life easier
8 II. Natural Resources Groups A. Air and windB. Fossil fuelsC. MineralsD. PeopleE. SoilF. SunlightG. WaterH. Wildlife
9 1. The atmosphere is the area surrounding the Earth A. Air and Wind1. The atmosphere is the area surrounding the Eartha. Air is the mixture of gases that surrounds the Earthb. Wind is the movement of airc. Water vapor, gases, and particulate can be found in the atmosphere
10 A. Air and Wind2. Weather - the conditions found in the atmospherea. includes moisture, humidity, temperature, movement, and pressure
11 A. Air and Wind3. Climate of an area helps determines which natural resources are found in an areaa. Climate - the condition of the weather in a particular location (rainfall, temperature, humidity, etc.)
12 1. Fossil fuels are natural resources used to provide energy B. Fossil Fuels1. Fossil fuels are natural resources used to provide energya. Fossil fuels took millions of years to makeb. The remains of decomposed plants and animalsc. Their energy comes from the energy produced by the plants and animals
13 2. Fossil Fuel Groupsa. Petroleum - liquid form of fossil fuels used to make gasoline and oils
14 2. Fossil Fuel Groupsb. Natural gas - gaseous form of fossil fuels used in heating and cooking
15 2. Fossil Fuel Groupsc. Coal – solid form of fossil fuels used in factories and in generating electricity
16 C. Minerals1. Natural inorganic substances on or in the earth2. Abiotic3. Mined from the earth4. Iron, brick, jewelry, coins, monuments, and concrete
17 D. People1. Help determine how other natural resources are used2. As population increases, natural resource use will increase3. Wise use of resources is necessary to ensure their future availability
18 E. Soil 1. Outer layer of the earth’s surface that supports life 2. Plants grow in soil, humans and other animals eat plants, humans and animals produce waste that provides nutrients for plants to grow, and the cycle continues3. soil can be easily eroded by misuse and neglect4. Soil must be protected in order for it to continue to be a resource
19 F. Sunlight 1. The source of almost all the energy used on Earth 2. The light from the sun produces solar energya. Autotroph, Heterotroph, Photosynthesis, Cellular Respirationb. People can also use this energy by using solar collectors
20 G. Water 1. A tasteless, colorless, liquid natural resource 2. ALL living things need water to survive3. Water is a naturally occurring compound made up of 2 atoms of Hydrogen and 1 atom of Oxygen4. Water can be found in three forms, solid, liquid, and gas
21 5. Water Cyclea. Movement of water from the earth’s surface to the atmosphere and back to the surfaceb. Water is continuously renewed/recycled through the hydrologic cycle
22 H. Wildlife1. All of the plants and animals that live in the wild2. Have not been domesticated
23 III. Renewable and Nonrenewable Resources A. Renewability is whether or not a resource can be restored after use
24 B. Renewable Natural Resources 1. Natural resources that can be replaced after use2. They can be renewed and used again, but it may take many years3. Soil is a renewable natural resource, however it is not a fast process4. Plants and water are other renewable natural resources
25 C. Nonrenewable Natural Resources 1. Natural resources that cannot be replaced after use2. Minerals and fossils fuels are two types
26 IV. Inexhaustible and Exhaustible Natural Resources A. Exhaustibility - whether or not a natural resource can be replenished as it is used
27 B. Inexhaustible Natural Resource 1. A resource that is continuously replenished; the supply of the resource will not run out2. Sunlight, wind, and water are inexhaustible natural resources
28 C. Exhaustible Natural Resource 1. A resource that is available in limited quantity and can be completely used2. Can be replaceable or irreplaceablea. replaceable natural resource can be replenished - most wildlifeb. irreplaceable natural resource - gone once it is used - fossil fuels and most minerals
29 V. Interdependent Relationships A. ALL natural resources depend on each otherB. This means that all living things depend on each other
30 V. Interdependent Relationships C. Humans need animals for food, clothing, and workD. Plants are used for food, medicine, and oxygen
31 V. Interdependent Relationships E. Plants depend on animals and humansF. Animals give off carbon dioxide that the plants needG. When organisms die, they decompose releasing minerals back into the soil for plants
32 Review/Summary Define and identify types of natural resources. Distinguish between renewable and nonrenewable resources.Explain the difference between inexhaustible and exhaustible resources.Explain the concept of interdependent relationships.
