What did detailed research of the ocean floor reveal? A. It is full of relief B. It is covered in thick sediments C. It is mostly flat with few features D. It is a vast plain Explanation: Research showed that the ocean floor is not a plain but has various features like mountains and trenches. 2 / 202. What are marine deposits found along the coastlines of South America and Africa? A. Precambrian age B. Tillite C. Jurassic age D. Placer deposits Explanation: The earliest marine deposits along the coastlines of South America and Africa are of the Jurassic age, suggesting the ocean did not exist before that time. 3 / 203. What was the primary force suggested by Wegener for continental drift? A. Magnetic forces B. Volcanic activity C. Convectional currents D. Pole-fleeing force Explanation: Wegener suggested that the pole-fleeing force, related to the Earth’s rotation, was responsible for continental drift. 4 / 204. What does the presence of tillite in different landmasses suggest? A. Similar geological histories B. Similar gold deposits C. Volcanic activity D. Identical fossil species Explanation: The presence of tillite in different landmasses suggests that these landmasses had similar geological histories, including glaciation. 5 / 205. What is the significance of the belt of ancient rocks from Brazil matching those from western Africa? A. Explains the formation of tillite B. Shows the distribution of fossils C. Provides evidence for placer deposits D. Indicates rocks of the same age across oceans Explanation: The matching belts of ancient rocks suggest that these continents were once connected. 6 / 206. What new information did post-World War II discoveries add to the understanding of continental drift? A. Ocean floor mapping B. Tillite formation C. Distribution of fossils D. Placer deposits Explanation: Post-World War II discoveries, particularly ocean floor mapping, provided new insights into the distribution of oceans and continents. 7 / 207. What is the name of the supercontinent that Wegener proposed? A. Pangaea B. Laurasia C. Gondwanaland D. Panthalassa Explanation: Wegener named the supercontinent Pangaea, meaning “all earth.” 8 / 208. What evidence does the matching of continents provide? A. Placer deposits B. Rocks of the same age across oceans C. Tillite deposits D. Continents fit together like a jigsaw puzzle Explanation: The matching of continents, particularly the coastlines of Africa and South America, suggests that they were once joined. 9 / 209. What are placer deposits? A. Glacial deposits B. Gold deposits C. Volcanic rocks D. Fossil remains Explanation: Placer deposits are gold deposits found in rivers and streams, formed from the weathering of gold-bearing rocks. 10 / 2010. Why were Wegener’s proposed forces for continental drift considered inadequate? A. They were not strong enough B. They were based on in C. They were not supported by evidence D. They were not well understood Explanation: Scholars considered Wegener’s proposed forces to be too weak to move continents. 11 / 2011. What is the significance of gold deposits in Ghana having a source in Brazil? A. Indicates continents were once connected B. Shows evidence of volcanic activity C. Provides evidence of tillite formation D. Explains the distribution of fossils Explanation: The gold deposits in Ghana having a source in Brazil suggest that these continents were once together. 12 / 2012. What is the convectional current theory? A. Spreading of the sea floor B. Formation of mountains due to volcanic activity C. Movement of continents due to tidal forces D. Circulation of heat within the mantle Explanation: The convectional current theory proposes that heat within the mantle creates circular currents, causing the movement of plates. 13 / 2013. What is Mesosaurus? A. A fossil plant B. A volcanic rock C. A type of gold deposit D. A small reptile Explanation: Mesosaurus was a small reptile adapted to shallow water, and its fossils are found in both South Africa and Brazil. 14 / 2014. What is tillite? A. Volcanic rock B. Sedimentary rock formed from glaciers C. Gold deposits D. Fossils of small reptiles Explanation: Tillite is a sedimentary rock formed from glacial deposits, providing evidence of past glaciation. 15 / 2015. What pattern does the distribution of earthquakes and volcanoes show? A. Random distribution across the Earth B. Concentrated in the interior of continents C. Aligned with mid-oceanic ridges and the rim of the Pacific Ocean D. Concentrated along coastlines Explanation: Earthquakes and volcanoes are concentrated along mid-oceanic ridges and the rim of the Pacific Ocean, known as the “Rim of Fire.” 16 / 2016. What is the significance of the age of rocks in the oceanic crust? A. They are much younger than continental rocks B. They are much older than continental rocks C. They are the same age as continental rocks D. Their age is not related to continental drift Explanation: Rocks in the oceanic crust are much younger than continental rocks, supporting the idea of seafloor spreading. 17 / 2017. Who first proposed the possibility of continents being joined together? A. Abraham Ortelius B. Edmond Hess C. Alfred Wegener D. Antonio Pellegrini Explanation: Abraham Ortelius, a Dutch map maker, first suggested the possibility of continents being joined together in 1596. 18 / 2018. What is the tidal force? A. Force caused by convectional currents B. Force caused by the attraction of the moon and sun C. Force caused by volcanic eruptions D. Force due to the Earth's rotation Explanation: The tidal force is caused by the gravitational pull of the moon and sun, creating tides in the oceans. 19 / 2019. What problem arises when identical species are found on either side of marine barriers? A. Explaining their distribution B. Identifying their habitat C. Determining their age D. Understanding their evolution Explanation: The presence of identical species on either side of marine barriers raises the question of how they crossed the ocean. 20 / 2020. What are mid-oceanic ridges? A. Deep trenches in the ocean floor B. Flat plains on the ocean floor C. Areas of thick sediment deposits D. Submerged mountain ranges Explanation: Mid-oceanic ridges are underwater mountain ranges formed by plate tectonics.
