Weathering |
Is a physical and chemical process that breaks down rocks into soil -Physical= heating/cooling -Chemical= acid rain, vegetation (plants: example: moss), microorganisms
|

|
Light can be |
1)Refracted- or bent when is passes from a substance of one density to a substance with a different density because it causes it to slow down or speed up; example: gas ->solid(air->glass), gas ->liquid (air ->water)
2)Reflected- or bounced off an object if the surface is smooth, shiny, or white. Light reflected off rough surfaces is scattered and results in a blurry or poor reflection.
3)Absorbed- or taken in by a dark or black objects |
|
|
Sound |
waves travel best in materials when the molecules are close together. -Sound does NOT travel through a vacuum (empty space without molecules) -Sound travels more slowly than light -Bounces off hard surfaces and results in echoes -Sonar measures sound waves bouncing off objects as do ultrasound medical devices |

|
Topographic maps
|
Use concentric circles (circles within circles) to show elevation (height) on maps. The more numerous the circles and the closer together they are on the map the greater the elevation. |
|
|
Succession |
Is the gradual change in a biome (biological community or ecosystem) over a long period of time. |

(Mutually beneficial) a relationship between different species that helps both of them by together. eg. Bacteria living in a cow's stomach. |
|
|
Parasite |
A plant or animal that lives at the expense of another living thing. |

Organism containing chlorophyll that makes food by photosynthesis. Found at the beginning of a food chain. |
|
|
Consumer |
Organism that eats organisms for nutrition. |
|
|
Decomposer |

|
Predator |
living things that kill and eat other things |
|
|
Prey |
living thing that is eaten by another living thing |
|
|
Warm-blooded |
organism that maintains a warm body temperature no matter what the temperature of the enviroment |
|
|
Cold-blooded |
organism whose body temperature depends on the enviroment |
|
|
Vertebrate |
animal with a backbone |
|
|
Invertebrate |
animal without a backbone |
|
|
Food Web |
overlapping food chains that show the flow of energy from producers to consumers. The ultimate source of all energy is the sun |
|
|
Food Chain |
link from a lower organism (usually a plant) to a higher organism and so on. |
|
|
Pollution |
contamination of the air, water, or land. It can be caused by burning, dumping waste, heating of water pesticides, etc |
|
|
Water Cycle |
Evaporation, condensation, precipitation |
