Front

What is the Continental Shelf?

Back

The Continental Shelf is the underwater land that extends from the shore of a continent to the deep ocean. It is usually shallow and rich in marine life.

Front

What is the Continental Slope?

Back

The Continental Slope is the steeply sloping area that connects the Continental Shelf to the deep ocean floor. It marks the transition from shallow to deep water.

Front

What is the Continental Rise?

Back

The Continental Rise is the gently sloping area at the base of the Continental Slope, where sediments accumulate before reaching the abyssal plain.

Front

What is an Abyssal Plain?

Back

An Abyssal Plain is a flat, deep ocean floor that is covered with thick layers of sediment. It is one of the flattest and smoothest areas on Earth.

Front

What does salinity mean?

Back

Salinity refers to the amount of salt dissolved in water. It is an important factor in determining the density and buoyancy of ocean water.

Front

What is the importance of the Continental Shelf?

Back

The Continental Shelf is important for fishing, oil drilling, and as a habitat for many marine species.

Front

How does the Continental Slope affect ocean currents?

Back

The Continental Slope can influence ocean currents by directing their flow and creating areas of upwelling, which brings nutrients to the surface.

Front

What is the difference between the Continental Shelf and the Continental Slope?

Back

The Continental Shelf is shallow and extends from the shore, while the Continental Slope is steep and leads down to the ocean floor.

Front

What role does salinity play in ocean ecosystems?

Back

Salinity affects the types of organisms that can live in different parts of the ocean, influencing biodiversity and food webs.

Front

What features are found on the ocean floor?

Back

The ocean floor includes features such as the Continental Shelf, Continental Slope, Continental Rise, Abyssal Plain, and ocean trenches.
