Ocean Layers and Landforms Quiz

Epipelagic Zone: The surface layer, extending to about 200 meters, where most ocean life is found due to sunlight penetration.
Mesopelagic Zone: Known as the "twilight zone," this layer ranges from 200 to 1,000 meters and has limited light access.
Bathypelagic Zone: Referred to as the "midnight zone," spanning 1,000 to 4,000 meters, characterized by darkness and cold temperatures.
Abyssopelagic Zone: Known simply as the "Abyss," this zone ranges from 4,000 to 6,000 meters with no light and near-freezing temperatures.
Hadopelagic Zone: The deepest zone starting from 6,000 meters, experiences extreme pressures of about 8 tons per square inch.

Ocean Surface: The area where wind interacts with water, creating waves and transferring energy.
Abyssal Plain: A nearly flat and deep-sea floor section, providing a stable environment for diverse life forms.
Mid-ocean Ridge: An undersea mountain chain formed at divergent plate boundaries, responsible for new ocean floor creation.
Continental Shelf: Underwater land that extends from the continent, important for marine ecosystems and resources.
Continental Slope: A steep incline marking the transition from continental crust to oceanic crust.

Trench: Extremely deep oceanic areas formed by subducting tectonic plates, often associated with tectonic activity.
Seamount: An underwater volcanic mountain that rises from the ocean floor, which can support unique marine life.
Volcanic Island: A volcanic mountain that reaches above sea level, formed through volcanic activity.

Gyre: A massive rotating ocean current system that influences climate, where pollution can accumulate.
Thermohaline Current: Deep-sea currents driven by variations in temperature and salinity, crucial for global ocean circulation.
Waves: Generated by wind, they propagate energy across the ocean surface.
Tides: Periodic rises and falls in sea level influenced by the moon's gravitational pull.
