What are the two types of coastlines?
A cliffed coast or abrasion coast is one where marine action has produced steep declivities known as cliffs. A flat coast is one where the land gradually descends into the sea. A graded shoreline is one where wind and water action has produced a flat and straight coastline.
What is an Amero trailing coastline?
Amero-trailing edge coasts occur in the middle of a tectonic plate and face a spreading center. The coast on the opposite side of the continent is a collision coast. Characteristics of Amero-trailing edge coasts include NO tectonic activity; a wide continental shelf and a wide, low coastal plain.
What is a leading edge coast?
trailing edge coast A coastal area that is not the site of subduction or plate collision but is located in the interior of a lithospheric plate; characterized by gentle slopes and low energywaves leading edge coast A coastal area that is the site of convergent or transform plate motion; associated with uplift, and a …
What is a collision coast?
A collision plate coast typically lies along the edge of a convergent plate. Collision plate coasts are often associated with earthquakes and volcanic activity. These coasts are relatively straight with narrow continental shelves and steep continental slopes.
What are the four types of coasts?
Types of Coastlines
- RIA COASTS AND FIORD COASTS. Coastlines of submergence include ria coasts and fiord coasts.
- BARRIER-ISLAND COASTS. The barrier-island coast is associated with a recently emerged coastal plain.
- DELTA COASTS.
- VOLCANO AND CORAL-REEF COASTS.
- FAULT COASTS.
- RAISED SHORELINES AND MARINE TERRACES.
What are the main types of coastlines?
Such a classification leads to the definition of three general tectonic types of coasts: (1) collision coasts, (2) trailing-edge coasts, and (3) marginal sea coasts.
What kind of plate boundary is associated with a trailing-edge coast?
Trailing-edge coasts are the result of plate divergence and are facing a spreading centre. In plate tectonics, the formation of an ocean is a spreading process between two newly formed plates.
What are the two types of coastlines found along eastern and western coastlines of North America?
There are two types of collision plate coasts: Continental collision plate coast: Continental coasts, such as the west coasts of North and South America, located along a collision boundary. Island arc collision plate coast: A coast located along the collision margin of an island arc, such as New Guinea and Japan.
What is the trailing edge of a tectonic plate?
Trailing-edge coasts or passive margins: coasts that are located away from plate boundaries and are generally tectonically stable because the continent and ad- joining ocean floor are of the same plate.
What are three types of coastal ecosystems?
Here’s a deeper dive into four types of coastal habitat: mangroves, salt marshes, seagrass meadows, and coral reefs.
What is the trailing-edge of a tectonic plate?
Is California a collision coast?
The southern California coastal region is an unique collisional tectonic margin. It is associated with the lateral movement of tectonic plates along the San Andreas Fault zone.
What is a trailing edge coast?
Trailing edge coasts are near the middle of a tectonic plate and far from the plate boundary. The characteristics all trailing edge coasts have in common are lack of tectonic activity (no earthquakes or volcanism); There are three types of training edge coasts:
What is a trailing-edge beach?
Trailing-edge beach at Canaveral National Seashore, Florida. Continental trailing-edge beaches—such as those seen on the Atlantic Ocean—see very little seismic activity and have a much gentler slope from inland mountain ranges to the coast.
What are the characteristics of Amero-trailing edge coasts?
Characteristics of Amero-trailing edge coasts include NO tectonic activity; a wide continental shelf and a wide, low coastal plain. There is abundant sediment deposition and therefore numerous depositional features.
What are the three categories of trailing plate margin coasts?
The three categories of trailing plate margin coasts: Neo-trailing plate margin coast: Coastline developed along the margin of a newly rifting land mass such as the Red Sea and the Gulf of California.
