**Second Semester**Test Practice For each of the following questions, record your answer on your paper before advancing to the next slide and viewing the correct answer.**Procedure**Construct 4 identical stream tables, using the same amount of sand in each table. Angle each stream table as shown to the right Pour one liter of water from the same height on to each stream table. Collect water and sand eroded from the table into the bucket. Dry the eroded sand. Measure the mass of the sand eroded from each table. Record results. • Students performed this experiment to test the effects of the slope of the stream table on the amount of sand eroded. • What is the manipulated (independent) variable in this experiment? • slope of the tables • amount of sand eroded • volume of water collected in bucket • volume of water poured on the tables 1**And the answer is…**• slope of the tables**Procedure**Construct 4 identical stream tables, using the same amount of sand in each table. Angle each stream table as shown to the right Pour one liter of water from the same height on to each stream table. Collect water and sand eroded from the table into the bucket. Dry the eroded sand. Measure the mass of the sand eroded from each table. Record results. What must be held constant in this experiment? time of day slope of table student recording results volume of water poured on the tables 2**And the answer is…**D. volume of water poured on the tables**In what type of cells would you expect to find a lot of**mitochondria?A. skin cellsB. blood cellsC. bone cellsD. muscle cells 3**And the answer is…**D. muscle cells**These conduct impulses from**the brain to muscles or glands Sensory neurons Motor neurons Interneurons Exoneurons 4**And the answer is…**B. Motor neurons**Meteorologists have predicted the following weather for**Kansas City, Missouri for the next three days. If the weather trend continues, what will Saturday’s forecast mostly likely look like? A B C D 5**When a rapidly moving cold air mass runs into a slow moving**warm air mass, the result is a(an) • cold front. • occluded front. • warm front. • stationary front. 6**And the answer is…**• cold front.**A scientist has conducted a study of changes in the size of**the Arctic ice field. • Satellite photographs were used to collect the data. • The following steps were involved: • Organize the data • Draw conclusions • Hypothesize that the ice cap is shrinking • Collect monthly photographs of the ice cap • Measure the field’s area in the photograph • Plot data on a graph • Report the findings What is the most likely order of the events in this study? 1, 2, 3, 4, 5, 6, 7 2, 3, 5, 7, 6, 4, 1 3, 4, 5, 1, 6, 2, 7 4, 3, 5, 1, 6, 7, 2 7**And the answer is…**C. 3, 4, 5, 1, 6, 2, 7**What conclusion about the large outer planets is supported**by the information in the table? As the diameter of the planet increases, the number of moons increases. As the distance from the sun increases, the period of revolution increases As the diameter of the planet increases, the period of rotation decreases. As the distance from the sun increases, the period of rotation decreases. 8**And the answer is…**B. As the distance from the sun increases, the period of revolution increases**Which planet in the above data table has the longest year?**• Jupiter • Saturn • Uranus • Neptune 9**And the answer is…**D. Neptune**As a research assignment for a science class, a student has**been asked to determine how many times Io revolves around Jupiter in one Jupiter year. To help answer this question, he has gathered the following facts from the library: • The same side of Io always faces Jupiter. • Io’s period of rotation on its axis is 1.8 Earth days. • One Jupiter year is equal to 12 Earth years. • By using this information and by performing a few calculations, the student should be able to complete the assignment. What can you conclude about Io’s period of revolution around Jupiter? It is less than its period of rotation. It is equal to its period of rotation on its axis. It is greater than its period of rotation on its axis. It is equal to one Jupiter year. 10**And the answer is…**B. It is equal to its period of rotation on its axis.**Joy and Trey put 15 mL in a graduated cylinder. They then**placed a rock in the cylinder and read the new volume in the container as 32 mL. What is the volume of the rock? • 15 mL • 22 mL • 17 mL • 47 mL 11**And the answer is…**C. 17 mL**23**12**Use the chart to answer the question.**Which statement is true based on the data presented? If both parents were Dd, then none of the offspring would be dwarf If both parents were DD, then none of the offspring would be dwarf If one parent were Dd and the other were dd, then none of the offspring would be regular If one parent were DD and the other were dd, then none of the offspring would be regular 13**And the answer is….**B. If both parents were DD, then none of the offspring would be dwarf**What can be found inside of organ “E”?**A. polyps B. villi C. hydrochloric acid D. salivary glands 14**And the answer is….**B. villi**What moon phase would be occurring if the moon is at**position E? 15**And the answer is…**New Moon**Which of the following would scientists use to measure**atmospheric pressure? • Telescope • Barometer • Anemometer • Microscope 16**And the answer is…**• B. Barometer**What season occurs in the Northern hemisphere when the Earth**is at position B during its revolution around the sun? 17**And the answer is…**Summer**What moon phase would be occurring if the moon is at**position G? 18**And the answer is…**First Quarter**Which process occurs only when a small space object**interacts with a larger space object? • Tectonics • Volcanism • Erosion • Impact cratering 19**And the answer is…**• D. Impact cratering**Which processes occur because a planet or another space body**is hot inside? • Tectonics and volcanism • Volcanism and erosion • Erosion and impact cratering • Impact cratering and tectonics 20**And the answer is…**• Tectonics and volcanism**What do all four gas giants have that terrestrial planets do**not have? • Atmospheres • Solid surfaces • Moons • Rings 21**And the answer is…**• D. Rings**What are the white stripes of Jupiter and the white spots of**Neptune? • Clouds high in the atmosphere • Smoke from volcanoes • Continents and islands • Holes in the atmosphere 22**And the answer is…**• Clouds high in the atmosphere**What season occurs in the northern hemisphere when the Earth**is at position D during its revolution around the sun? 23**And the answer is…**Winter**Carl is curious as to whether or not he should wear a coat**to school. Which of the following instruments would give him the best information to help him make his decision? • thermometer • psychomotor • anemometer • barometer 24**And the answer is…**• thermometer**Betty wants to find out the amount of water she collected in**a cup during a rainstorm.
