What is the primary driving force behind coastal ocean circulation?

  1. Wind

  2. Tides

  3. Coriolis Effect

  4. Density Differences


Correct Option: A
Explanation:

Wind is the primary driving force behind coastal ocean circulation, as it generates surface currents and waves that transport water and energy.

Which of the following is a characteristic feature of coastal upwelling?

  1. Cold, nutrient-rich waters rise to the surface

  2. Warm, nutrient-poor waters rise to the surface

  3. Downwelling of surface waters

  4. Formation of coastal fronts


Correct Option: A
Explanation:

Coastal upwelling is a process where cold, nutrient-rich waters from deeper layers rise to the surface, bringing essential nutrients for marine life.

What is the term used to describe the mixing of seawater and freshwater in coastal areas?

  1. Estuarine Circulation

  2. Tidal Mixing

  3. Coastal Convergence

  4. Oceanic Fronts


Correct Option: A
Explanation:

Estuarine circulation refers to the mixing of seawater and freshwater in estuaries, where river water meets ocean water, creating a unique environment.

Which coastal ecosystem is known for its high productivity and biodiversity?

  1. Coral Reefs

  2. Mangrove Forests

  3. Salt Marshes

  4. Kelp Forests


Correct Option: A
Explanation:

Coral reefs are highly productive and biodiverse ecosystems, supporting a wide variety of marine life and providing important ecological services.

What is the term used to describe the process of sediment transport along coastlines?

  1. Longshore Drift

  2. Rip Currents

  3. Beach Nourishment

  4. Coastal Erosion


Correct Option: A
Explanation:

Longshore drift is the process by which sediment is transported along coastlines by waves and currents, shaping beaches and barrier islands.

Which human activity is a major contributor to coastal pollution?

  1. Oil Spills

  2. Overfishing

  3. Deforestation

  4. Urban Runoff


Correct Option: D
Explanation:

Urban runoff, carrying pollutants from impervious surfaces, is a significant source of coastal pollution, affecting water quality and marine ecosystems.

What is the term used to describe the process of protecting and restoring coastal ecosystems?

  1. Coastal Conservation

  2. Marine Protected Areas

  3. Integrated Coastal Management

  4. Beach Replenishment


Correct Option: C
Explanation:

Integrated Coastal Management is a comprehensive approach to managing coastal resources and activities, aiming to balance environmental protection with sustainable development.

Which coastal phenomenon is characterized by strong, narrow currents flowing away from the shore?

  1. Rip Currents

  2. Tidal Currents

  3. Ocean Gyres

  4. Coastal Jets


Correct Option: A
Explanation:

Rip currents are powerful, narrow currents that flow away from the shore, posing a hazard to swimmers and surfers.

What is the term used to describe the process of sediment deposition at the mouth of a river?

  1. Delta Formation

  2. Barrier Island Formation

  3. Beach Nourishment

  4. Coastal Erosion


Correct Option: A
Explanation:

Delta formation occurs when sediment carried by a river is deposited at its mouth, creating a fan-shaped landform.

Which coastal ecosystem is characterized by salt-tolerant plants and provides important habitat for wildlife?

  1. Coral Reefs

  2. Mangrove Forests

  3. Salt Marshes

  4. Kelp Forests


Correct Option: B
Explanation:

Mangrove forests are coastal ecosystems dominated by salt-tolerant trees and shrubs, providing habitat for various marine and terrestrial species.

What is the term used to describe the process of seawater intrusion into coastal aquifers?

  1. Salinization

  2. Desalination

  3. Aquifer Recharge

  4. Coastal Erosion


Correct Option: A
Explanation:

Salinization refers to the process where seawater intrudes into coastal aquifers, increasing the salinity of groundwater.

Which coastal phenomenon is characterized by a rapid rise in sea level, often associated with storms?

  1. Storm Surge

  2. Tidal Bore

  3. Tsunami

  4. Coastal Erosion


Correct Option: A
Explanation:

Storm surge is a rapid rise in sea level caused by strong winds and low atmospheric pressure during storms, posing a significant threat to coastal communities.

What is the term used to describe the process of sediment removal from coastal areas?

  1. Coastal Erosion

  2. Sedimentation

  3. Beach Nourishment

  4. Longshore Drift


Correct Option: A
Explanation:

Coastal erosion refers to the process where sediment is removed from coastal areas by waves, currents, and other natural forces.

Which coastal ecosystem is characterized by dense underwater forests of giant kelp?

  1. Coral Reefs

  2. Mangrove Forests

  3. Salt Marshes

  4. Kelp Forests


Correct Option: D
Explanation:

Kelp forests are coastal ecosystems dominated by giant kelp, providing habitat and food for various marine organisms.
