OCS Exam 3 2023 with 100% correct answers

Characteristics of a Coast - correct answerdetermined by: •whether they are on an active or passive plate margin •the amount of wave energy •the slope of the land eustatic changes - correct answerlong term, widespread changes Erosional Coasts - correct answera coast in which erosive processes exceed depositional ones (dominant processes remove coastal material) Characteristics of Erosional Coasts - correct answer•high energy coasts (lots of wave action due to many storms and a long fetch) •dominated by rocks •refraction concentrates wave energy at headlines •over time, erosional forces create a smooth shoreline Examples of an Erosional Coast - correct answerMaine, British Columbia, Southern tips of South America and Africa Depositional Coasts - correct answera coast in which processes that deposit sediment exceed erosive properties (steady or growing due to accumulation of sediments) Characteristics of Depositional Coast - correct answer•low-energy coasts, protected and not subject to frequent, large waves •dominated by sediments (beaches) •gradient in sediments
