Question | Answer |
homogenous mixture | you can not see its other particles....... example= apple juice |
heterogenous mixture | you can see the different parts of it......... example= fruit salad |
pure substance | a pure substance is a substance with only one particle= aluminum foil. |
particle theory | all particles attract to eachother all matter is made up of tiny particles particles are moving all the time particles move faster when heated particles ahve spacs between them |
Global Warming | heating of Earths atmosphere |
greenhouse effect | methane, nitrous oxide, water vapour and carbon dioxide, mix in the atmosphere and create a sort of roof. The roof causes the heat from the sun to stay in the atmosphere and heat up the earth |
pros of global warming | More crop seasons, nice beaches and waters, shorter snow seasons, warm weather |
cons of Global Warming | polar icecaps melting, rising seas levels, animals losing their homes and habitats, great lakes are drying up, we will all die in the end |
heat | is the warmth of something.... can be tested on a thermometer |
matter | matter is everything |
primary succesion | starting from scratch, starts with a volcano making a clearing, weeds start to grow, shrubs start to grow, trees grow. |
secondary succesion | have a bit left, starts with seeds blowing in, blackberry bushes growing, small tree come, humans come and clear cut then leave the land for a couple of years. |
kinetic energy | measures the movement of something |
thermal energy | measures the heat of something |
thermal contraction | when the particles of something get cooled and move closer together and slow down. this causes the objetc to get smaller or have less volume |
thermal expansion | when the object's particles get heated and they move faster and spread out. this causes the object's volume and mass and size to grow. |
conduction | heat transfer through solids |
convection | heat transfer through fluids (liquids, gas) |
radiation | suns heat or heat from something else. |
seperating a solution | evaporate something or use distillation |
dissolving rate | to speed up the dissolving you: heat the water or stir and crush the object... to slow down: do the opposite |
energy | the ability to do something |
temperature | the heat or coolness of soemthing |
biotic | a living thing |
abiotic | a non living thing |
Carnivore | an animal that relys on meat as its food |
herbivore | an animal that relys on vegatation as their food source |
omnivore | animals that rely on vegatation and meat as their food source |
solar energy | energy from the sun |
wind enrgy | energy from teh wind |
geothermal energy | ENERGY FROM UNDER THE GROUNd |
biome | a large place |
wave energy | energy from the waves |
biodiversity | the vegatation or animasls in a community |
community | a place of organized living |
tsunami | large wave from earthquakes |
rainforests | lots of rain, warm and humid |
deserts | not much rain, hot and dry |
lakes | no salt water |
oceans | salt water, large |
biofuels | fuels that can power things that don't hurt our environment |
environment | the world |
dissolving | making something go away.... |
hypothosis | a guess of something |
procedure | the order of things |
materials list | what you need |
oxygen | something humans cannot live without |
water | needed for survival... hydrates us |
food | gives us energy, needed to live |
shelter | somethings humans can live without but is strongly needed |
