Hypothesis •d.Conclusion •e. Procedure 5 A series of steps scientists follow to solve problems •a. hypotheses •b.controlled experiments •c. scientific methods •d.variables 6 What is the one factor that differs between a control group and the experimental group in a controlled experiment? •a. hypothesis •b.controlled experiment •c. scientific method •d.variable 7 Experiments that test only one factor at a time, and which consist of a control group and one or more experimental groups are •a. scientific methods •b. controlled experiments •c. hypotheses •d. variables 8 Why do many experiments include several trials instead of a single trial? • a. Repetition of trials makes data easier to analyze. • b. Repetition of trials increases the accuracy of the results. • c. Repetition of trials increases the sample size of the experiment. • d. Repetition of trials lets the experimenter change the experimental procedure. 9 Volume = L x W x H What is the volume of a block that has the length: 9.5cm, width: 5.2cm, and height 4.75cm? •a. 234.65cm •b. 234.65cm³ •c. 234.65cm² •d. 245.6cm³ 10 Density = M/V What is the density of an object that has a mass of 405.7g and a volume of 95.3cm³? •a. 4.26g •b. 4.26g/cm³ •c. 4.26cm³ •d. 4.26g/cm² 11 Earth is divided into three compositional layers and five physical layers. The lithosphere is one of the physical layers. The lithosphere includes some or all of which two compositional layers? • a. • b. • c. • d. core and crust crust and mantle mantle and core core and mesosphere 12 Where are volcanoes most likely to form? •a. •b. •c. •d. near the center of continents along bodies of water along plate boundaries in mountainous areas 13 The deep interior of the Earth can be mapped using •a. seismic waves •b. information from drilling expeditions •c. sonar •d. ocean waves 14 A break in Earth’s crust along which blocks of crust slide relative to one another is •a. •b. •c. •d. a plate a fault a deformation an earthquake 15 What are the mechanisms that have been proposed to explain the movement of Earth’s tectonic plates? •a. slab pull and sea-floor spreading •b. mantle convection and continental drift •c. mantle convection, ridge push, and slab pull •d. sea-floor spreading and continental drift 16 Scientists think the continents once formed a large, single landmass that broke apart, and the continents slowly drifted to their present locations. What is the name given to this hypothesis? •a. •b. •c. •d. continental rise continental shelf continental drift continental slope 17 Tectonic plates consist of •a. continental crust •b. both continental and oceanic crust •c. oceanic crust •d. mesosphere 18 New ocean floor is most likely to form as movement occurs at which type of plate boundary? •a. a divergent boundary •b. a subducting boundary •c. a transform boundary •d. a convergent boundary 19 Rock that comes from volcanoes. •a. sedimentary •b. metamorphic •c. igneous •d. rock cycle 20 Rock that forms form sediments being cemented together. •a. sedimentary •b. metamorphic •c. igneous •d. rock cycle 21 Rock that is formed from extreme heat and pressure. •a. sedimentary •b. metamorphic •c. igneous •d. rock cycle 22 Rock that changes from one type to another by geologic processes •a. sedimentary •b. metamorphic •c. igneous •d. rock cycle 23 Which of the following objects is a fossil? •a. a sinkhole formed by a retreating glacier •b. a sedimentary rock that formed a long time ago •c. a crystal formation suspended from the ceiling of a cave •d. the remains of an organism preserved in limestone 24 Which of the following statements is not information that could be learned by studying fossils? •a. how environments have changed over time •b. how organisms have changed over time •c. the absolute location of the organisms birthplace •d. the relative ages of rocks 25 Which of the following is at type of fossil that would be most helpful in estimating the age of a rock layer? •a. •b. •c. •d. bone fossil trace fossil trapped fossil index fossil 26 Zane and his class have been collecting fossils and minerals on a field trip. They have gotten turned around in the woods. Zane uses his compass to figure out which way they should go to get back to the campsite. What direction will the compass needle point toward? •a. •b. •c. •d. south north east west 27 Why did scientists develop the geologic time scale? •a. to better understand the arrangement of rock layers •b. to better classify index fossils •c. to better determine the absolute ages of rocks •d. to better study Earth’s immense history 28 Earth’s history is divided into time units in the geologic time scale. Put the following time divisions in proper order from largest to smallest: era, period, epoch, eon. •a. •b. •c. •d. epoch, period, era, and eon eon, era, period, and epoch era, period, epoch, and eon period, eon, era, and epoch 29 According to the rock record, Earth's geologic history covers what amount of time? •a. 2.5 million years •b.4.6 billion years •c. 8.8 million years •d.7.3 billion years 30 A glacier is a •a. Series of frozen lakes that line up parallel to one another •b. Series of frozen seas that rest in the interior of continents •c. Large body of ice that does not move across the earth’s surface •d. Large body of ice and snow that shows evidence of movement 31 Glaciers form in cold areas with lots of snow. The snow must turn into ice to form a glacier. How does this happen? •a. The cold wind blows across the top of the snow, turning it into ice. •b. The snow builds up, and its weight compresses the snow below into ice •c. The snow melts as it falls and then freezes once it hits the cold ground. •d. The temperature on the ground is cold enough to turn the snow into ice. 32 What happens to a rock when it is weathered during the process of soil formation? •a. It is broken into smaller pieces. •b. It is built up as material is deposited. •c. It is moved by wind, air, or water. •d. It is changed into another type of rock. 33 Which soil horizon is primarily responsible for the soil’s fertility? •a. Horizon A, because it contains humus and other organic nutrients that plants need. •b. Horizon B, because plant roots can grow down into the smaller rock fragments. •c. Horizon C, because most of the groundwater is stored in this horizon •d. Horizon D, because it is the parent rock that breaks up to form soil. 34 You have just analyzed a soil sample. In the sample you found silt, sand, clay, and organic matter.
