  • why are electric cords coated with plastic?
    because plastic is cheap
    because plastic blocks the flow of electric current
    because plastic is flexible
    because plastic allows electric current to flow
  • Energy caused by the movement of electrons.

  • three kinds of cells: oak leaf, squirrel muscle, fern leaf. which will have chlorophyll
    the oak leaf and fern leaf
    only the fern leaf
    only the squirrel muscle
    all of the cells will contain chlorophyll
  • An organism that breaks down wastes and dead organisms
    Decomposer
  • what organelle is the brain of the cell
    cytoplasm
    nucleus
    cell wall
    cell mebrane
  • melted rock below the earth's surface
    magma
  • Tiny, one celled organisms found in water that break down organic matter
    Bacteria
  • What is the BEST comparison of static electricity and electric current?
    static runs through wires, current jumps across wires
    static has negative charges, current positive charge
    static is build up of electrons, current is flow
    static uses open circuits, current uses closed circuits
  • How can you make an electromagnet stronger?
    replace the copper wire with plastic wire
    increase the electric current flowing through the wire
    wrap the wire around the iron core fewer times
    replace the iron core with a copper core
  • An organism that can make its own food.
    Producer
  • which is weathering
    a river carries sediment across a valley floor
    tree roots breaking rocks into smaller pieces
    wind blows sand from dune to dune
    ocean waves dropping sand on a beach
  • what is true about levees?
    they prevent erosion of river banks
    they allow deposition on floodplains
    they limit coastal flooding
    they help control flooding along rivers
  • support microorganisms are harmful
    microorganisms live in soil, water, air
    algae release oxygen into the air as waste
    mosquitoes can transmit protozoa that cause malaria
    bacteria and fungi are decomposers
  • When weathered rock is picked up and moved
    erosion
  • which is not true?
    the cell membrane of animal cells is thicker than plant cell
    an animal cell cannot be seen without a microscope
    a plant cell cannot be seen without a microscope
    animal and plant cells have organelles

    Photosynthesis
  • which event causes a mountain to form over time?
    a river slows down at its mouth
    a glacier melts
    a volcano erupts
    a river floods
  • why are electric cords coated with plastic?
    because plastic is cheap
    because plastic is flexible
    because plastic allows electric current to flow
    because plastic blocks the flow of electric current
  • why are electric cords coated with plastic?
    because plastic blocks the flow of electric current
    because plastic is cheap
    because plastic allows electric current to flow

    Temperature
  • What causes a liquid to change to a gas
    an increase in temperature
    a decrease in temperature
  • which statement describes how deposition builds up the surface of a floodplain?
    rainwater seeps into the ground and freezes
    a river flows over its banks and slows down
    a river slows down as it flows into the ocean
    lava flows from a volcano and piles up
  • Processes by which rock, sand, and soil are broken down and carried away (i.e. weathering, glaciation)
    Erosion
  • how do seeds and spores compare?
    both are parts for reproduction
    both occur in flowering plants
    neither grows in soil
    only seeds grow into new plants
