OFFICAL vocab only
| Term | Definition |
|---|---|
| Ecology | The study of relationships between living organisms and their physical environment |
| Ecosystem | A community of living and non-living things interacting in an environment |
| Population | A group of the same species living in a particular area |
| Biodiversity | The variety of all living things in an area, including different plants, animals, and other organisms. |
| High biodiversity | many different kinds of life; helps ecosystems stay healthy |
| Thermal energy | The total energy of moving particles in a substance (heat energy) |
| Conduction | The flow of energy through a sold by collisions of its atoms. Energy is transferred through direct contact |
| Convecion | Heat transfer through the movement of fluids (liquids or gases). It is caused by differences in density. Cold, dense fluids will sink causing warm, less dense fluids to rise. |
| Radiation | Heat transfer through electromagnetic waves, like sunlight |
| Kinetic energy | the energy of an object in motion |
| Energy transfer | The movement of energy from one object or system to another |
| Reflection | wave bouncing off of a surface |
| Absorbtion | waves energy is taken in |
| Transmission | wave passes through the material |
| Ecosystems composition | physical and biological components |
| Emprirical evidence | observations and data |
| Conductors | objects and materials that conduct and give off energy well |
| insulators | objects and materials that contain energy |
| Frequency | how many waves pass a certain point in a certain amount of time |
| wavelength | the distance between peaks of waves |
| amplitude | the height of waves |
| Analog signals | change smoothly, like squiggly lines, hard to copy and don't travel long distances well |
| Digital signals | More reliable, ones and zeros, patterns and puless. More reliable and don't lose quality |
| Electromagnectic waves | can travel without a median, different types of waves (microwave, infrared, visible light, ultraviolet light, x-rays, gamma rays. |
| Sound waves | needs a median bc of vibration |
| Rotation | Spinning on an axis |
| Revolution | Moving around another object |
| Gravity | The force that pulls things towards an object's center |
| Solar system | includes the sun and everything that revolves around it. |
| Moon | an object that revolves around a planet. |
| Astroids | large rocks that orbit the sun |
| sun | central and largest body in our solar system. |
| comets | ice and dust that orbit the sun |
| Metroid | rock fragments in space |
| Summer solstice | June 21st when the northern hemisphere is facing the sun |
| Winter solstice | December 21st when the northern hemisphere is facing away from the sun |
| Equinox | equal hours of daylight and nighttime. most direct sunlight at the equator |
| atmosphere | the layer of gases that surrounds earth |
| Air pressure | the force of a column of air pushing down on an area |
| Air mass | a large body of air with roughly the same tempature and humidity |
| Weather | the condition of the atmosphere at a specific time and location |
| Climate | average weather conditions in a specific area over a long period of time |
| Atmospheres composition | mixture of gases: 78% nitrogen, 21% oxygen and 1% other gases. |
| High air pressure | sunny, low cloud cover, good weather |
| Low air pressure | precipitation, clouds, cloud cover bad weather |
| Anemometer | mesures wind speed |
| Barometer | mesures air pressure |
| Thermometer | mesures tempature |
| Front | a boundary between air masses causes change in weather |
| Condensation | forms clouds |
| Sun + water cycle | the driving force of the water cycle |
| Gravity and water cycle | pulls water downward. |
| Winds | caused by differences in air pressure |
| Lithosphere | rock at earths surface forms a continus shell around earth. |
| Hydrosphere | the thin layer of water above the lithospehere |
| Igneous | molten magma or lava cools and hardens |
| sedimentary | sediments and organic materials get buried and compressed or cemented together |
| metamorphic | pre-exsisting rock is exposed to heat and pressure |
| Earth's interior | provides energy that melts rocks and makes magma |
| sun in the rock cycle | makes weathering and erosion to form sedimentary rocks |
| Soil | weathered rock, organic material, water and air |
| Weathering | Caused by the action of expanding ice temperature changes animal and plant activity and the action of chemicals |
| Erosion | Movement of sediment to a new location gravity moving water wind and glaciers are all agents |
| crust | outermost layer of earth |
| mantle | liquid like plastic |
| outer core | liquid iron |
| inner core | solid iron and nicle |
| Ring of fire | most active volcano sightings around the pacific ocean |
