Science The Earth's Resources-Lesson 3
| Question | Answer |
|---|---|
| what are examples of land resources | land itself, soil,rocks and minerals |
| what is a use of land resources | housing |
| what is soil | a mixture that forms when rock weathers into tiny pieces |
| how are nutrients added to soil to make good farmland soil | when dead plants, animals and other organisms decay |
| why is it a slow process to make new soil | because the rocks have to weather over time and break into tiny pieces |
| what else is needed besides nutrients to make good rich soil | water, air and minerals are added to the mixture |
| how do farmers use the soil | to producr the food people eat such as fruits and vegetables, meat and poultry, milk and grains |
| what food can you make from wheat | bread and cereal |
| what do farmers produce that make clothes | cotton and wool |
| where does cotton come from | cotton plants |
| where does wool come from | sheep |
| how can a forest be used to produce products for people | the wood from trees is used to build houses and schools, some wood is processed to make paper, hiking and observing nature |
| what mineral is an important land resource | coal |
| what is coal used for | it is used as fuel for heating and generating electricity |
| what do processed minerals from the land get used as | aluminum foil, jewelry,silverware, bicycles |
| what mineral is used to make aluminum foil | bauxite |
| where are factories built | on the land near the materials that they will use |
| where would a factory that makes frozen vegetables be built | near a farm where the vegetable grow |
| why would a factory that makes aluminum be in a area where electricity is less expensive | the process to make bauxite into aluminum uses a lot of electricity |
| where are most of the things we use everyday produced | farms,mines and factories |
| what could happen to land resources where the farms, factories and mines are | they could be damaged or used up from producing everday things |
| how can you help protect land resources | recycling |
| what ways does the process of turning bauxite into aluminum use resources | mining bauxite changes the land, it uses the mineral bauxite, uses a lot of electricity to process and makes waste |
| how does using electricity use up land resources | using more electricity means more mining for coal |
| how can we help to create less mining | recycle cans and use less aluminum and less bauxite is need from mines |
| how can recycling cans protect resources | no mining is need to get more bauxite, it uses less electricity and less air pollution |
| what ways can you reuse to help protect land resources | refill plastic water bottles, rechargeable batteries, use a lunch box instead of paper bag, use cloth towels instead of paper towel, reduce amount of things you buy, choose products with less packaging |
| what 3 things can you do to help protect the land resources | recycle, reuse and reduce |
