Tides, Currents, and Waves

What causes tides?

• Global warming

• Wind patterns

• Earth's rotation

• Gravitational pull of the moon and the sun

Explain the difference between spring tides and neap tides.

• Spring tides have lower high tides and higher low tides

• Spring tides occur during the neap tide phase

• Neap tides have no effect on the tides

• Spring tides have higher high tides and lower low tides, while neap tides have lower high tides and higher low tides.

How do currents affect marine life?

• Currents can affect marine life by transporting nutrients, larvae, and organisms, influencing migration patterns, and impacting the distribution of food sources.

• Currents have no impact on marine life

• Currents only affect the temperature of the water

• Marine life is not affected by currents

What are the factors that influence wave size?

• Wind speed, wind duration, and fetch

• Boat traffic, underwater topography, and cloud cover

• Tidal range, water salinity, and air pressure

• Water temperature, water depth, and moon phase

Describe the process of wave formation.

• The process involves the transfer of energy from the moon to the water's surface, creating ripples that develop into waves.

• Waves are formed when the water evaporates and condenses, causing a disturbance on the surface.

• Wave formation is caused by the movement of tectonic plates under the ocean floor.

• The process involves the transfer of energy from the wind to the water's surface, creating ripples that develop into waves.

What is the Coriolis effect and how does it impact ocean currents?

• It is the name of a popular ocean current, and it has no impact on other ocean currents.

• It is a type of wave that only occurs in the Pacific Ocean, and it causes ocean currents to slow down.

• It is a type of fish that lives in the deep sea, and it has no impact on ocean currents.

• It is the apparent deflection of moving objects due to the rotation of the Earth, and it causes ocean currents to curve.

How do tides and currents impact coastal erosion?

• Coastal erosion is caused by factors unrelated to tides and currents

• Tides and currents actually prevent coastal erosion by depositing more sediment on the shore

• Tides and currents have no impact on coastal erosion

• Tides and currents can contribute to coastal erosion by carrying sediment away from the shore and causing abrasion against the coastline.

Explain the concept of wave refraction.

• The decrease in wave height as they approach the shore

• The increase in wave speed as they approach the shore

• The bending of waves as they approach the shore due to changes in wave speed caused by varying depths.

• The reflection of waves off the shore

What are the different types of waves found in the ocean?

• Earthquake waves, tsunami waves, and volcanic waves

• Heat waves, cold waves, and pressure waves

• Wind waves, swell waves, and tidal waves

• Rain waves, storm waves, and hurricane waves

Discuss the importance of understanding tides, currents, and waves for sailors and surfers.

• They can rely solely on GPS for navigation

• It helps them to plan their routes, avoid dangerous conditions, and take advantage of favorable conditions.

• It has no impact on their safety or navigation

• Understanding tides, currents, and waves is only important for marine biologists
