Coasts are the most dynamic landscapes on Earth - what does this mean?
They are the most common of all landscapes
They are the most colourful of all landscapes
They are the most changeable of all landscapes
They are the most noisy of all landscapes
What makes coasts more dynamic (changeable) than most other landscapes?
The number of people who choose to live there
The energy of the ocean
The impact of wind and rain
The variety of plant and animal species found there
What is responsible for creating most of the waves in the ocean?
Movements of large sea creatures deep down
Container ships carrying goods between continents
The gravitational pull of the moon
The frictional contact of winds blowing over the ocean
Which of the following does NOT influence the strength / energy of a wave?
The distance the wave traveled before it hit land
Whether it breaks on a sandy or stony beach
The strength / speed of the wind that created it
The length of time the wind blew for
Which coast of the island of Ireland receives the highest energy waves?
north
south
east
west
The distance of open ocean over which a wave travels before it breaks on a coastline is known as the
(a)
Which of the following do NOT meet the coastline of Ireland?
The Pacific Ocean
The Atlantic Ocean
The Irish Sea
The Mediterranean Sea
What is the prevailing (most common) wind direction for Ireland?
northerly
easterly
south-westerly
south easterly
Which of the following statements is NOT true?
Coasts are constantly under attack from erosive and weathering processes
Erosion is mostly through the action of the oceans and seas
Weathering is the decay and break up of rocks by the effects of the atmosphere and the environment
There are 3 main types of erosion - physical, chemical and biological
Name the coastal erosion process that would transform pebble B to look like pebble A
chemical weathering
corrosion
attrition
hydraulic action
This rock clearly shows the strength of which process?
physical weathering
attrition
biological weathering
chemical weathering
Which of the following are examples of biological weathering?
Rocks repeatedly expand during the heat of the sun and then contract in cold night time temperature weakening the surface which eventually crumbles
Creatures like barnacles, limpets, anenomes and lichens fix themselves to rock surfaces and can produce chemicals to break down the rock to get the minerals they need
The constant motion of waves and currents causes sand and pebbles to grind against the base of a cliff wearing it away
Roots of trees and shrubs growing on a cliff top force their way down through topsoil into cracks in the rock and force them to widen
Seabirds living on cliffs produce large amount of droppings which can attack the minerals in the rock
Which of the four processes of coastal erosion do NOT wear away the cliff?
corrosion
attrition
hydraulic action
solution
Which of the following rock types would be most easily dissolved by acids in seawater (solution)?
basalt
granite
limestone
slate
The weight of waves crashing into cracks in the cliff compresses air which widens the cracks. this is known as...
solution
physical weathering
attrition
hydraulic action
Which of the following is NOT true?
The base of a cliff often erodes the fastest
Hydraulic action will do most damage to cliffs during times when there are storm waves
Coastlines with extremely hot or cold climates will be more affected by physical weathering than the UK
Attrition acts to make stones and pebbles more sharp and angular over time
Which process has changed the appearance of this statue over time?
biological weathering
chemical weathering
physical weathering
solution
