Presentation Transcript

Weathering – breaking down of rocks into smaller pieces (sediments) because of ‘weather’: ice, freezing, rain, wind & temperature & plants (roots)

Sediment – small pieces of broken rock, sand, silt

Erosion- the movement of sediment from one place to another: wind, moving water (river), ice (glacier), gravity (landslide)

Deposition- the ‘deposit’-ing or dropping of sediments from water erosion (delta) or wind erosion

Natural Resource – anything that nature gives us that we use

Renewable Resource- a resource that can be replaced

(trees, wind, water cycle, sunlight)

Nonrenewable Resource- a resource that takes millions of years to replace (fossil fuels: natural gas, oil/petroleum, coal


Food Chain – energy flow is shown with an

The SUN is the first part of any food chain

  • PRODUCERS- produce their own food= PLANTS

    (all plants get their energy from the sun-photosynthesis)

  • CONSUMERS- must consume their food

    (must get their energy from other sources)

  • Herbivore- eats only plants

  • Carnivore- eats other animals: meat/flesh

  • Omnivore- eats both plants & animals/meat

    ECOSYSTEM- a combination of plants and animals living in one community all connected

LIFE CYCLES- stages an organism goes through

Frog- egg, tadpole, young frog, adult

Butterfly- egg, larva (caterpillar), pupa, adult

Grasshopper- egg, nymph (no wings), (molts & loses

its hard outer skeleton), adult (incomplete metamorphosis)

Flower- egg, seed, seedling, mature plant, flower/pollen

Animals– egg, embryo, infant, adolescent, adult

Mammal- nurse their young (mammary/milk gland)


A nonliving solid in crystal form, which forms

in nature- under the ground-even the air

(minerals do not contain rocks!)

Cleavage/Fracture- a crack or break

in a mineral

Streak – the color left behind when a

mineral is rubbed on a white tile

Hardness- ability to scratch another

mineral (Mohs scale is 1-10) talc=1

[fingernail=2.5] diamond=10

Luster- how shiny or dull a mineral is

(shiny, dull, earthy, waxy, metalic, glassy)

Rock a solid in nature that is made of one or more minerals
ROCK: a solid in nature that is made of one or more minerals

  • IGNEOUS ROCK- forms from a volcano’s lava that cools (‘ignite’)

    -cools deep underground = more crystals form

    -cools above ground= not as many crystals form

  • SEDIMENTARY ROCK- when bits of ‘sediment’ push and cement together deep under water (fossils)

  • METAMORPHIC ROCK- form deep underground from heat & pressure changing from one form into another (‘morph’- means change)

Rock cycle

IGNEOUS ROCK- can break down into sediments (from wind or water), fall to bottom of river/ocean, cement from weight of water into SEDIMENTARY ROCK

METAMORPHIC ROCK- Can melt in a magma chamber and erupt out of vocano, cool into an IGNEOUS ROCK. Or, be at the edge of a plate, be pushed up exposed above ground, be eroded by wind/water into sediments, cemented into SEDIMENTARY ROCK

SEDIMENTARY ROCK- can be at edge of plate, be pushed down into mantle, be heated & pressed into METAMORPHIC ROCK.

Earth moon sun

  • Moon Phases- appear to change [as seen from Earth] caused by the Moon revolving around Earth.

  • Seasons – caused by Earth’s axis being tilted

    *when Northern Hemisphere is tilted TOWARD Sun, its having SUMMER

    *when Northern Hemisphere is tilted AWAY from Sun, its having WINTER

  • Earth’s ROTATION (spinning) on its axis causes:

    1.DAY & NIGHT: One complete spin= 12 hrs of day & 12 hrs of night. (sun rising & sun setting)

    2.Moon appears to move across the Earth’s sky

    3.Sun appears to move across the sky in the daytime

  • MOON rotates same time it revolves, so we only see one side of moon



ARTHOPODS (spider, scorpions, crab) , INSECTS, SNAILS, SQUIDS, SEA SLUGS,





ROOTS- anchor/hold plants in ground; take in/absorb water & nutrients from soil

STEM – support plant to stand tall & strong; carries water & nutrients up/ glucose food down

LEAF/NEEDLE – use energy from sun, carbon

dioxide to make food: glucose

FLOWER – attracts pollinators, helps some

plants reproduce, many grow into fruit

(containing a seed) CONE- not a fruit, but

disperses seeds

SEED – structure that contains a young plant

and its food supply



  • STAMEN- male organ; thin stalk topped with a saclike anther produces pollen

  • ANTHER – male organ that produces pollen

  • POLLEN- male part contains sperm, which is needed to fertilize the female egg


  • PISTIL- female organ that contains the ovary-where eggs are made

  • OVARY- female structure where eggs are made

  • PETAL – puter part of flower that attracts

  • Pollinators: butterflies, birds, bats, wind (25%),

  • bees/insects

  • SEED- fertilized egg that will grow into a seedling

  • GERMINATION – when a seed sprouts

  • SEEDLING – when the small plant grows roots &

  • a stem (a very small beginning of the plant

  • SEED DISPERSAL- the spreading of seeds through

  • Wind, animal dung, catching on moving animals.

  • Animals bury seeds, floating on water,
