Costal Enviorments Flashcards
What is corrasion?
Corrasion is the process of erosion caused by the scraping and wearing away of rock surfaces by the action of sediment and other materials carried by water or wind.
True or False: Abrasion is primarily caused by the force of moving water alone.
False
Fill in the blank: Hydraulic action is the erosion caused by the ____ of water.
force
What is the main difference between corrasion and abrasion?
Corrasion involves the mechanical scraping of surfaces, while abrasion refers to the wearing away of materials due to friction.
What process involves the chemical dissolution of minerals in water?
Solution
Multiple choice: Which of the following is NOT a type of erosion? A) Corrasion B) Hydraulic action C) Photosynthesis D) Attrition
C) Photosynthesis
What is attrition in the context of erosion?
Attrition is the process where eroded materials collide with each other, causing them to break into smaller, rounder particles.
True or False: Hydraulic action can occur in both rivers and coastal environments.
True
Fill in the blank: The process of _____ involves the physical breakdown of rocks by the impact of particles carried by wind or water.
abrasion
What is one effect of hydraulic action on coastal cliffs?
Hydraulic action can lead to the undercutting of coastal cliffs, causing them to collapse.
Multiple choice: Which process is primarily responsible for the smoothness of pebbles in a river? A) Corrasion B) Attrition C) Solution D) Hydraulic action
B) Attrition
True or False: The solution process involves only physical changes to the rock.
False
What type of materials are typically involved in corrasion?
Sediments such as sand, gravel, and other debris carried by water or wind.
Fill in the blank: _____ can cause significant erosion in areas with strong wave action.
Hydraulic action
What is the primary agent of attrition?
Moving water or wind carrying eroded materials.
Multiple choice: Which of the following processes is mainly chemical? A) Abrasion B) Solution C) Attrition D) Corrasion
B) Solution
True or False: Abrasion can only occur in water environments.
False
Fill in the blank: The combination of _____ and hydraulic action can lead to the formation of features like sea caves.
corrasion
What is the outcome of prolonged attrition on sediment?
Sediment becomes smaller and more rounded over time.
Multiple choice: Which type of erosion involves the physical impact of particles? A) Solution B) Hydraulic action C) Corrasion D) Weathering
C) Corrasion
True or False: Solution can occur in freshwater environments only.
False
What is a common example of hydraulic action?
Waves crashing against a cliff face.
Coastal zone
Where the land meets the sea
Offshore zone
370 km
