| Question | Answer |
|---|---|
| Solar energy | alternative energy from the Sun |
| Wind energy | uses turbine to generate energy; created by uneven heating from the Sun |
| Biomass | alternative energy from plants and living things |
| Hydroelectric energy | energy generated by moving water at dams |
| Geothermal energy | Energy created using heat with the Earth |
| Nonrenewable | Resources that can not be replaced once used (oil, coal, natural gas) |
| Renewable | resources that can be quickly replaced once used (water, sunlight, wind) |
| Fossil Fuels | another term for nonrenewable resources (coil, oil, and nature gas) |
| Conservation | using less resources by saving and recycling; protecting the resources we have |
| Carbon dioxide | gas created by burning fossil fuels |
| Igneous | rocks created by cooling magma (granite is an example) |
| Metamorphic | Rocks created by heat and pressure (marble is an example) |
| Sedimentary | rocks created by compacting and cementing (example: sandstone) |
| Rock Cycle | the processes that change rocks over time |
| Heat and pressure | processes in the earth that create metamorphic rocks |
| Melting and cooling | the processes that change rocks to igneous rocks |
| Talc | the softest mineral (used in powders) |
| Intrusive Igneous | Rocks that cool and solidify from magma inside the Earth |
| Extrusive igneous | Rocks that cool and solidify from lava on the Earth's surface |
| Fossils | the trace or remains of an organism that lived long ago, most commonly preserved in sedimentary rock |
| Superposition | law that states younger rocks lie above older rocks |
| Recycling | Conservation method that saves resources by reusing them |
| Mineral | naturally occuring inorganic solids |
| Sun | the original source of energy for ALL of Earth's resources |
| Uniformitarianism | Principle that shows the Earth is very old (processes that change the Earth are the same) |
| Catastrophism | Principle that states Earth's changes happen suddenly |
