Describe the difference between a pure substance and a mixture. - ANSWER-Pure Substance is an element or a compound; a substance with a fixed chemical composition. Mixture is a combination of two or more pure substances. Examples of Pure Substance - ANSWER-Gold - Au Diamond (Carbon) - C Water - H₂0 Methane - CH₄ Examples of Mixtures - ANSWER-Ocean Water Air Rock Alloy Fabric Differentiate between a heterogeneous and homogeneous mixture - ANSWER-Heterogeneous mixture- Components unev...

Define convection current. - Circular currents in the mantle caused by the magma being heated by the core off the Earth. Explain how convection cells cause local winds - Local winds are the result of convection on a small scale. They occur when Earth's surface is heated unevenly. For example, you've probably noticed that large bodies of water, such as lakes and oceans, are often much cooler than the nearby land surfaces during the day. The air above the warm surface absorbs heat from the ...

Define wave. - ANSWER-A disturbance that travels through space and time accompanied by the transfer of energy. It is a vibration, a vibration is a wiggle, and a wiggle that travels is called a wave. Waves carry energy from one place to another. Explain the difference between a transverse wave and a longitudinal wave, and give examples of each. - ANSWER-- Transverse Waves- Waves that move up and down, vibrations perpendicular to the direction the wave travels. Types: Light/electromagnetic, (ra...

Define potential energy - ANSWERSThe energy a system has due to its shape or position. The potential to do work. Example of potential energy - ANSWERSLetting go of a box after picking it up (falls to the ground). Example of electrical potential energy - ANSWERSEnergy between the clouds and ground in a thunderstorm Example of chemical potential energy - ANSWERSfood and gasoline Example of gravitational potential energy - ANSWERSWater tower- Water pumped to the top of a water tower ...

Explain the concept of natural selection. - ANSWERSIt is a process where organisms with advantageous traits leave more offspring than organisms with other traits - causing populations to change over time. (key mechanism of evolution) variation - ANSWERStraits vary from individual to individual heritable traits - ANSWERSA trait that can be passed on genetically from parent to offspring. fitness - ANSWERSthe number of offspring an organism leaves over its lifetime compared to other indivi...
