#1
Which of the following factors primarily determines wave height?
Wind speed
ExplanationWind speed is the primary determinant of wave height.
#2
What is the most common type of coastal erosion?
Abrasion
ExplanationAbrasion is the predominant form of coastal erosion.
#3
What is the term used to describe the rise and fall of ocean water level caused by gravitational forces of the moon and sun?
Tide
ExplanationTides refer to the cyclic rise and fall of ocean water due to gravitational forces.
#4
Which type of coastline typically has long stretches of sandy beaches?
Submergent coastline
ExplanationSubmergent coastlines often feature long sandy beaches.
#5
Which of the following describes a constructive wave interference?
Waves amplify each other
ExplanationConstructive interference results in waves reinforcing each other.
#6
Which phenomenon causes the bending of waves as they approach the coast?
Refraction
ExplanationRefraction causes waves to bend as they near the coastline.
#7
What is the primary driving force behind longshore drift?
Wind
ExplanationWind primarily drives longshore drift.
#8
What is the term for the time it takes for one full wavelength to pass a fixed point?
Wave period
ExplanationWave period is the duration of one complete wave cycle.
#9
Which of the following is NOT a factor influencing wave size and strength?
Water temperature
ExplanationWater temperature does not significantly influence wave size or strength.
#10
Which of the following coastal features is created by wave erosion and typically has a flat top?
Wave-cut platform
ExplanationA Wave-cut platform is formed by wave erosion and usually has a flat top.
#11
Which coastal feature is formed by the erosion of headlands and the deposition of sediment in bays?
Spit
ExplanationA Spit forms from headland erosion and bay sediment deposition.
#12
What is the primary factor determining the size and shape of coastal landforms?
Wave energy
ExplanationWave energy is the main determinant of coastal landform size and shape.
#13
What is the term for the movement of water caused by the gravitational pull of the moon and sun?
Tide
ExplanationTide results from the gravitational pull of the moon and sun.
#14
What is the term for the process where sediment is deposited by a receding wave, forming ridges parallel to the shoreline?
Swash
ExplanationSwash refers to sediment deposition forming ridges parallel to the shoreline.
#15
What term describes the retreat of a cliff face caused by the hydraulic pressure of waves forcing air into cracks?
Wave hydraulic action
ExplanationWave hydraulic action causes the retreat of a cliff face by forcing air into cracks.
