The highest earthquake magnitude ever recorded on a Richter scale is

here are the answers to the questions:

14. The highest earthquake magnitude ever recorded on a Richter scale is

• E. 9.5. The 1960 Valdivia earthquake in Chile holds the record for the highest magnitude ever recorded, measuring 9.5 on the Richter scale.

15. Which of the following is associated with vulcanicity?

• B. Formation of crater lakes. Vulcanicity (volcanism) involves the eruption of molten rock and gases, which can lead to the formation of depressions (craters) that later fill with water to become crater lakes.

16. The similarity between Arete and Cirque is that they are features of

• C. glaciated highlands. Both aretes (sharp, knife-edge ridges) and cirques (amphitheater-like valleys) are distinctive landforms created by glacial erosion in mountainous, high-altitude regions.

17. The movement of large particles in a series of hops along the stream bed is

• C. saltation. Saltation is a process of sediment transport where particles are lifted from the stream bed by the current, carried a short distance, and then fall back down, only to be lifted again in a hopping motion.

18. The making of ridges across the slope to control erosion is

• A. contour ploughing. Contour ploughing involves tilling the soil along the contours of a slope, creating ridges and furrows that run perpendicular to the direction of water flow, which helps to slow down runoff and reduce soil erosion.

19. The act of obtaining information about the earth surface without direct contact to it is

• E. remote sensing. Remote sensing is the science of acquiring information about the Earth's surface without actually being in physical contact with it, typically using satellites or aircraft.

20. The geographical factor that does not attract high population is

• D. high relief. Areas with high relief (steep slopes, mountains) are generally difficult for settlement, agriculture, and infrastructure development, thus tending to have sparse populations.

21. Which of the following is a natural factor affecting land transportation in Nigeria?

• E. Rugged terrain. Rugged terrain, such as mountains, hills, or dense forests, presents natural obstacles to the construction and maintenance of roads and railways, thereby affecting land transportation.

22. The tourist attraction centre that is famous for yachting and swimming in Nigeria is

• D. Nike lake. Nike Lake in Enugu is a known recreational spot that offers opportunities for boating, swimming, and potentially yachting, making it the most suitable option among those listed.

23. Which of the following is a product of heavy industries?

• E. Ship. Heavy industries are characterized by large-scale production, significant capital investment, and often produce large, complex products or basic materials. Building a ship fits this description.
