This type of tectonic boundary is the plate boundary in the middle of the Atlantic Ocean.

What is divergent?

100

Living In water, Unattached, Floating, Drifts with currents, are all used to classify these organisms.

What is plankton?

100

The area between the high tide and low tide marks is known by this name.

What is the intertidal zone?

100

This warm current flows along the eastern coast of North America and is part of the Atlantic Meridional Overturning Circulation.

What is the Gulf Stream?

100

This type of wave, generally created by wind, can be found in oceans, bays, rivers, lakes, and other types of water.

What are surface waves?

200

This is the deepest part of the ocean, located in the western Pacific Ocean near the Mariana Islands.

What is the Mariana Trench?

200

Plankton have two major groupings.

What are Phytoplankton and Zooplankton?

200

This is the area where freshwater from rivers meets and mixes with saltwater from the ocean, creating a highly productive coastal habitat.

What is an estuary?

200

This large-scale ocean current system, powered by wind and differences in water density, helps regulate global climate by transporting heat across the globe.

What are the thermohaline currents?

200

The energy of this phenomenon is proportional to its height multiplied by its width, meaning a larger one of these will have more energy.

What is a wave?

300

This gently sloping area of the ocean floor extends from the edge of a continent before dropping off steeply.

What is the continental shelf?

300

This animal, known for its ability to change color and texture, can squeeze through tiny openings to escape predators.

What is a squid?

300

This term describes the force exerted by ocean waves on coastal structures, sediment, and organisms, influencing erosion and shoreline changes.

What is wave stress?

300

This large system of rotating ocean currents, driven by the Earth's wind patterns and the Coriolis effect, can be found in both the Northern and Southern Hemispheres.

What is a gyre?

300

This extremely powerful wave is created by an earthquake or tectonic plate shift and carries a significant amount of energy.

What is a tsunami?

400

This term refers to the flat, vast areas of the ocean floor covered in thick layers of sediment.

What are abyssal plains?

400

Despite its massive size, this gentle giant of the ocean feeds primarily on tiny plankton by filtering them through its baleen plates.

What is a blue whale?

400

This term refers to the cloudiness or haziness of water caused by suspended particles, such as sediment, plankton, and pollutants.

What is turbidity?

400

These currents are primarily driven by wind patterns and affect the top 100 meters of the ocean, playing a key role in distributing heat across the globe.

What are surface currents?

400

These waves are created by the gravitational pull of the moon and sun, and they affect the rising and falling of sea levels.

What are tidal waves?

500

This type of ocean floor feature forms where one tectonic plate is forced beneath another.

What is a trench?

500

This marine crustacean can produce one of the loudest sounds in the ocean by snapping its claw, creating a shockwave to stun its prey.

What is a pistol shrimp?

500

This occurs when different species or human activities compete for space, resources, and habitats along the coastline, such as in estuaries or coral reefs.

What is competition?

500

This type of current flows parallel to the shoreline, driven by waves hitting the coast at an angle and transporting sand and sediment along the beach.

What is a longshore current?

500

Despite their size and movement, these do not transfer water mass from point A to point B; they only transfer this.

What is energy?
