AICE Marine Syllabus Assignment Exam with Questions and Answers

AICE Marine Syllabus Assignment Exam with Questions and Answers describe the four main types of erosion: by ice, water, wind and gravity ANSWER Ice erosion can be caused when glaciers move over land. Water erosion can deal with water and/or falling structures. Wind erosion can occur when sediment is picked up by wind. Water can erode and weather, such as moving sediment or hitting into something. describe sedimentation as the deposition of suspended particles ANSWER Deposition is when the particles are placed somewhere and can often make new structures. understand how the speed of water flow and particle size affect the removal, transport and deposition of particles ANSWER When water moves faster, it can often carry larger particles with it. Large particles deposit first and smaller particles stay on the water. define the littoral zone as the intertidal region on a shoreline, between the highest and lowest spring tide marks ANSWER Where the land meets the sea is the littoral zone. state examples of the littoral zone, including rocky shores, sandy shores, muddy shores, estuaries and deltas ANSWER Rocky shores have a rocky substrate. Sandy shores are made up of loose deposits and have a gradual slope towards the ocean. Muddy shores are least exposed to erosion and weathering, and sedimentation is the main factor in the creation. Estuaries are where freshwater and saltwater meet. Deltas are low lying triangular areas that bring water from lakes to oceans.
