Presentation Transcript
slide1

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

slide2

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

FLOW OF ENERGY

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

slide4

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)

MINERAL PROPERTIES

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
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
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
invertabrates
INVERTABRATES

DO NOT HAVE BACKBONES

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

VERTABRATES

HAVE BACKBONES

AMPHIBIANS, REPTILES, BIRDS, MAMMALS, FISH,

PLANT PARTS & STRUCTURES:

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

slide12

PLANT SEXUAL [MALE/FEMALE] REPRODUCTION

  • MALE PARTS:
  • 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
  • FEMALE PARTS:
  • 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,
