| Wavelength | Feature that distinguishes waves on the Electromagnetic Spectrum |
| Wave | A disturbance that transfers energy from place to place |
| Crests | Highest part of a transverse wave |
| Longitudinal Wave | waves that move parallel to direction they are traveling |
| Amplitude | Maximum distance particles of a medium move from rest position |
| Air Temperature | Affects the speed of sound waves traveling through air |
| Refraction | BENDING of a wave due to change in speed |
| Standing wave | An incoming wave combines with a reflected wave--appears to be standing still |
| Seismic waves | Produced by earthquakes |
| Medium | Material through which a wave travels |
| Outer space | Sound does not travel through this |
| Doppler Effect | Changing pitch of a police car's siren as it moves by you |
| Echolocation | Bats use this to locate food and to navigate |
| Sound travels more SLOWLY | in dense materials |
| Electromagnetic waves transfer energy without this... | a medium |
| Speed | All electromagnetic waes have the SAME |
| Opaque | A material that absorbs or reflects any light that strikes it |
| Concave mirror | Mirror that curves INWARD |
| When white light strikes a black object... | No light is reflected |
| Lithosphere | The ocean floor is an example of this sphere.. |
| TOPOGRAPHIC map shows... | Elevation, relief and slope |
| Steep slope | Shown by CLOSELY SPACED contour lines |
| Closed loop--small dashes pointing to inside shows... | A depression in the ground |
| Rock type and climate | Factors determining rate of weathering |
| Soil formation begins with... | rock |
| Bedrock | Solid layer of rock beneath the soil |
| Humus | Decayed organic material IN soil |
| Decomposers | Break down and digest the remains of dead organisms |
| Erosion by water and wind | Loss of soil not protected by plant cover |
| A Horizon | Topsoil found in this layer |
| Erosion | Natural forces move weathered rock and soil from place to place |
| Mass movement is caused by... | Gravity |
| Tributary | Stream or river running into another stream/river |
| Delta | These are built up by deposition |
| Kinetic Energy | Type of energy involved when a river moves sediment and erodes its banks |
| gravel | Type of sediment deposited first when river slows down |
| More water enters the river... | the river's speed will increase |
| Continental vs Valley Glaciers | Continental Glaciers thicker and larger |
| Wind blowing across water | Energy that produces waves |
| Deflation | Wind removes surface materials |
