- Q1What type of evidence do scientists use to support the theory that Earth's crust is divided into moving plates?The distribution of earthquakes and volcanic activity along plate boundariesIdentical soil types covering the entire EarthThe uniform climate across all continentsThe same species of plants found in all parts of the world30sSCI.7.10A
- Q2Which evidence supports the theory of plate tectonics by showing that the continents were once connected?The fit of the continents, such as the west coast of Africa and the east coast of South AmericaThe size of mountain ranges on each continentThe temperature differences between continentsThe similar clothing styles of ancient human populations30sSCI.7.10A
- Q3Which geological principle helps determine the relative age of rock layers?The theory of relativityThe law of thermodynamicsThe principle of uniformitarianismThe law of superposition30sSCI.7.10A
- Q4What evidence supports the idea that continents have moved over geological time?The discovery of identical plants in different climate zonesThe distribution of similar fossils across continents currently separated by oceans.The observation of species that never change over timeThe occurrence of the same weather patterns worldwide30sSCI.7.10A
- Q5What does the discovery of marine fossils on mountain tops suggest about Earth's history?Marine life has always thrived in high-altitude regions.The fossils were transported by birds from the ocean.Weather patterns have always been the same worldwide.It suggests that those areas were once covered by oceans.30sSCI.7.10A
- Q6Which geological process is responsible for the formation of mountain ranges?Evaporation of seawater creating landmassesThe collision and convergence of tectonic platesDeposition of sedimentary rocksErosion caused by wind and water30sSCI.7.10A
- Q7How does the theory of plate tectonics explain the occurrence of earthquakes?Earthquakes occur only when volcanoes erupt.Earthquakes happen randomly without any explanation.Earthquakes are caused by strong winds shaking the ground.Earthquakes occur due to the movement and interaction of tectonic plates along faults.30sSCI.7.10A
- Q8What does fossil evidence tell us about Earth's past life forms?Fossil evidence shows that life forms have always remained the same.Fossil evidence shows the types of organisms that lived in the past and how they have changed over time.Fossil evidence indicates the current climate conditions of Earth.Fossil evidence proves that all species evolved simultaneously.30sSCI.7.10A
- Q9How does the principle of superposition help scientists understand Earth's history?By identifying the chemical composition of each rock layerBy measuring the depth of rock layers to determine their exact ageBy determining the relative ages of rock layers, with older layers being deeper than younger onesBy arranging fossils in chronological order based on size30sSCI.7.10A
- Q10What type of evidence shows that continents have moved over time, supporting the theory of plate tectonics?The presence of identical trees on multiple continentsThe temperature variation in different continentsMatching geological formations and fossils found on different continentsWater levels in different oceans30sSCI.7.10A
