Science Topic 6 Test
| Nonrenewable Resource | A natural resource that cannot be replaced in a useful time frame. Examples are oil, coal, natural gas, and nuclear fission (Fossil Fuels) |
| Renewable Resource | A resource that is either always available or is naturally replaced in a relatively short amount of time |
| Wind Energy | Turbines are used to generate electricity by spinning and activating a generator by using wind power |
| Solar Energy | Photovoltaic cells convert the energy from the sun to electricity using solar panels |
| Hydroelectric Energy | People use dams to restrict the flow of the river by controlling how much water passes by and turbines convert the energy of moving water into electricity |
| Geothermal Energy | This uses the heat inside the Earth to generate electricity |
| Bioenergy (Biomass) | Plant-based materials can be burned to create energy |
| Passive Solar | Lets sunlight pass through glass to heat a room or building - Example: Greenhouse |
| Active Solar | The sunlight is captured by solar cells, which can then power things - Example: Solar panels |
| Three ways minerals can form | Living things (Organic materials), magma/lava, and solutions |
| Living Things | Coral creates a hard outer skeleton which provides protection. Once the coral is dead, the skeleton is left behind and may get buried and broken down into smaller fragments. |
| Magma/lava | When hot magma cools, it hardens into solid rock. The rock is made of crystallized minerals and when lava erupts from the ground, it cools and hardens. |
| Solutions | The elements in the solutions crystallize, forming a mineral. |
| Why are minerals important to humans? | Minerals are important to humans because they are used in the productions of buildings, cars, electronics, and jewelry, sculptures, and other works of art are often made with minerals. |
| What is groundwater? | It's not evenly distributed around Earth and the presence depends on the type of rock layers in Earth's crust |
| What is surface water? | Freshwater found on Earth's land surface and it's not evenly distributed around the world. It depends on atmospheric patterns and temperature |
| Coal | Formed from the remains of plants that died long ago in and around swampy areas. |
| Oil (Petroleum) | Made of the remains of small animals, algae, and other organisms. |
| Natural Gas | Trapped in pockets within layers of deep rock below Earth’s surface. (They use the method of fracking to collect and store natural gas) |
| How humans use salt water for a better use | Humans use the process of desalination to remove salt and minerals from salt water to make it freshwater. Also, factories can use solar energy to convert salt water into fresh water, but both are expensive and require a lot of energy to do so. |
| The negatives to using resources that we find in the water and the negatives | |
| Human impacts on the distribution of fossil fuels | As the human population has grown, fossil fuels have become less abundant (Existing or available in large quantities). Humans burn fossil fuels and we use lots of fossil fuels in everyday life. |
