1 PROFICIENCY REVIEW #2

2 WHICH OF THE FOLLOWING IS NOT A RENEWABLE ENERGY SOURCE? Nuclear

3 BASED ON IT S POSITION ON THE PERIODIC TABLE, URANIUM IS A METAL.

4 KNOW THE DIFFERENCE Convection movement of heat through a fluid. Conduction movement of energy, like electricity. Refraction to bend light. (example is why a spoon looks bent in a glass of water) Radiation energy from the sun.

5 WHAT HAPPENS TO ELECTROSTATIC FORCE AS AN OBJECT GETS CLOSER? It increases think of a magnet the closer together you bring it, the stronger the force of attraction.

6 ENVIRONMENTAL CHANGES HAVE CAUSED MOST EXTINCTIONS.

7 THE HOTTEST STARS ARE BLUE.

8 NUCLEAR ENERGY: Fission to break apart (Helium into 2 Hydrogen atoms) Fusion to join together (2 Hydrogen come together to make a Helium molecule) In both cases, matter is changed to energy.

9 IMAGES FROM A SPACE TELESCOPE (HUBBLE) ARE NOT DISTORTED, THAT IS WHY THEY ARE BEST TO USE.

10 THE FORCE ACTING ON AN OBJECT BEING DRAGGED ACROSS THE FLOOR = FRICTION.

11 BOUNDARY ON THE OCEAN FLOOR BETWEEN PLATES IS A MID-OCEAN TRENCH!

12 MITOCHONDRIA Cellular Respiration ATP Energy Found more in muscle cells

13 THE BOND ANGLE OF WATER IS BENT.

14 WHILE WATER TRAVELS THROUGH THE WATER CYCLE, WHY DOES THE WATER EVAPORATE AND THE SALT DOES NOT? Salt compounds do not evaporated from the water solution because they have a higher evaporation point than the water. So, the water evaporates, leaving the salt behind.

15 KMT Kinetic Molecular Theory Which has the highest kinetic energy? Ice water, Ice cream, Hot coffee, or Boiling water? BOILING WATER! The hotter something is, the greater the kinetic energy. LIQUID GAS SOLID

16 CURRENTS IN A BATTERY WIRE PRODUCE AN ELECTROMAGNETIC FIELD. SO, WHEN YOU HOLD A COMPASS NEAR A BATTERY WIRE, IT WILL CHANGE DIRECTIONS.

17 PHOSPHORUS Number of protons 15 Number of neutrons 16 Number of electrons P Phosphorus

18 ONE ADVANTAGE TO SEXUAL REPRODUCTION IS GREATER VARIATION AMONG ORGANISMS.

19 WHAT IS THE MAIN CAUSE OF GLOBAL WIND PATTERNS? Rotation of the Earth Coriolis effect

20 THE GREEN HOUSE EFFECT LEADS TO An increase in temperature An increase in the levels of carbon dioxide Acid rain *The greatest contributor to the green house effect increasing the levels of CO 2 in the atmosphere is the burning of fossil fuels.

21 PNEUMONIA LEADS TO AN INCREASE IN FLUIDS IN THE LUNGS, WHICH DECREASES THE OXYGEN TO THE CELLS.

22 MOH S HARDNESS SCALE, AND THE PERIODIC TABLE ARE BOTH SIMILAR BECAUSE THEY ARRANGE THINGS ACCORDING TO SIMILAR PROPERTIES. Hardness Mineral Associations and Uses Talc Talcum powder. 2 Gypsum Plaster of paris. Gypsum is formed when seawater evaporates from the Earth s surface. 3 Calcite Limestone and most shells contain calcite. 4 Fluorite Fluorine in fluorite prevents tooth decay. 5 Apatite When you are hungry you have a big "appetite". 6 Orthoclase Orthoclase is a feldspar, and in German, "feld" means "field". Quartz 8 Topaz The November birthstone. Emerald and aquamarine are varieties of beryl with a hardness of Corundum Sapphire and ruby are varieties of corundum. Twice as hard as topaz. 10 Diamond Used in jewelry and cutting tools. Four times as hard as corundum.

23 ELEMENTS THAT ARE IN NUCLEAR FUSION LIKE THE STARS AND SUN ARE Hydrogen and Helium

24 COMPARING GENETIC SEQUENCES WILL BEST TELL HOW CLOSELY TWO SPECIES ARE RELATED.

25 HUBBLE S LAW: The universe is expanding at a constant rate. It appears to be moving away from us.

26 PUNNETT SQUARES:

27 WHY WOULD A GENETIC MUTATION NOT BE PASSED ON? Because it is SOMATIC, or occurs within the body cells, and is not inherited.

28 THE ROLE OF A DECOMPOSER IN AN ECOSYSTEM IS TO BREAK DOWN DEAD ORGANIC MATTER.

29 WHY DOES A HOT AIR BALLOON RISE WHEN HEATED? Hot air rises, cold air sinks when compared to ambient temperature in the air.

30 HOW IS METAMORPHIC ROCK FORMED? Heat and pressure.

31 WHICH SUBSTANCE CAN BE SEPARATED EASILY? HETEROGENEOUS OR HOMOGENEOUS Heterogeneous you can pick out the individual parts because they are different.

32 WHAT DOES IT MEAN TO BE UNETHICAL IN SCIENCE? Fudging data Making stuff up Not doing multiple trials

33 MOST OF THE WORLD S ENERGY COMES FROM THE SUN SOLAR ENERGY.

34 THE HIMILAYAN MOUNTAINS ARE GAINING HEIGHT BECAUSE TWO PLATES ARE CONVERGING OR RUNNING INTO EACH OTHER AND UPLIFTING CAUSING THE LAND TO RISE.

35 INCREASING THE NUMBER OF RESEARCH GROUPS IS AN ETHICAL WAY OF GETTING A MEDICINE APPROVED FASTER.

36 TECTONIC PLATE MOTION CREATES WHAT ENERGY SOURCE? Geothermal

37 WHEN A BODY CELL DIVIDES, IT PRODUCES TWO COPIES WITH THE SAME DATA. MITOSIS

38 THE DIRECTION OF THE PREVAILING WINDS IS FROM WEST TO EAST.

39 2 PROTONS, 2 NEUTRONS, 3 ELECTRONS WHAT IS THE CHARGE OF THE ION? -1

40 IF THE EARTH IS TWO TIMES THE SIZE, AND THE DISTANCE TO THE MOON STAYS THE SAME GRAVITATIONAL ATTRACTION WILL INCREASE!
