Erosional Processes Quiz Coats

What is erosion?

• The process of building up land

• The wearing away of land

• The flooding of coastal areas

• The conservation of marine life

What is the coast?

• The deepest part of the ocean

• The boundary of a continent

• The area between the land and the sea

• A protected marine area

What is the term used to describe the coastal erosion process that involves the force of water against the coast?

• Solution

• Hydraulic action (pressure)

Which coastal erosion process is characterized by the wearing down of rock particles by friction?

• Hydraulic action (pressure)

• Attrition

• Corrasion

• Solution

What is the process called where water compresses air in cracks, leading to rock weakening and breaking off cliffs?

• Erosion

• Hydraulic Action

• Sedimentation

• Chemical Weathering

What is attrition in the context of coastal erosion?

• The process by which rock is dissolved by chemical reactions

• The process by which rock fragments are worn down into smaller, rounded pieces by hydraulic action and corrosion

• The process by which rock is broken down by the impact of other rock particles carried by water

• The process by which rock is broken down by the freezing and thawing of water

What is the result of the erosion process known as attrition?

• Formation of sand dunes

• Formation of pebble beaches

• Formation of sea stacks

• Formation of cliffs

What term is used to describe the erosion that occurs when waves carry rocks that scrape and wear away the base of a sea cliff?

• Attrition

• Corrosion (abrasion)

• Sedimentation

• Hydrolysis

What causes the chemical action known as corrosion in the context of sea water reacting with rocks?

• Heat from the sun

• Pressure from waves

• Salts and acids in sea water

• Organic matter decomposition

Which types of rocks are particularly prone to corrosion by the solution process?

• Granite and basalt

• Sandstone and quartzite

• Limestone and chalk

• Slate and marble
