• Question 1 of 5 1. Question Consider the following statements about bioerosion: Bioerosion is a type of physical erosion primarily caused by living organisms. The growth of plant roots can cause bioerosion by creating cracks in rocks. Bioerosion solely depends on plant life and does not involve other organisms. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: b) Bioerosion is a form of physical erosion caused by the activities of living organisms, making statement 1 correct. Plants contribute significantly to this process by sending roots into rock crevices, expanding these openings, and eventually breaking down the rock, as described in statement 2. However, bioerosion is not limited to plants alone; animals such as burrowing creatures or marine organisms like mollusks also contribute to bioerosion, Hence statement 3 is incorrect. Bioerosion demonstrates how living organisms play a role in the gradual disintegration of geological formations, affecting both terrestrial and aquatic environments. Incorrect Solution: b) Bioerosion is a form of physical erosion caused by the activities of living organisms, making statement 1 correct. Plants contribute significantly to this process by sending roots into rock crevices, expanding these openings, and eventually breaking down the rock, as described in statement 2. However, bioerosion is not limited to plants alone; animals such as burrowing creatures or marine organisms like mollusks also contribute to bioerosion, Hence statement 3 is incorrect. Bioerosion demonstrates how living organisms play a role in the gradual disintegration of geological formations, affecting both terrestrial and aquatic environments.

• Question 3 of 5 3. Question Consider the following statements about the formation of marine resources: Coral reefs are formed by the cooling and solidification of lava under the ocean. Sand and gravel are formed by the sedimentation of decomposed marine life. Minerals can form from the slow cooling of lava, allowing crystalline structures to develop. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: a) Statement 1 is incorrect because coral reefs are not formed by cooling lava; they are created by coral larvae attaching to underwater rocks and forming reefs over time.
