U4C14-15 24-25S1-3 Biogeochemical Process & Ocean Movements

Front

What is upwelling?

Back

Upwelling is a process where deep, cold, nutrient-rich water rises to the surface, providing essential nutrients for marine organisms.

Front

What do surface currents primarily result from?

Back

Surface currents are mainly caused by wind.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects, such as air and water, due to the rotation of the Earth, influencing ocean currents and weather patterns.

Front

Define biogeochemical cycles.

Back

Biogeochemical cycles are natural processes that recycle nutrients in various chemical forms from the environment to organisms and then back to the environment.

Front

What are the two primary sources of internal energy driving matter movement?

Back

The decay of radioactive isotopes and gravitational energy from Earth's original formation.

Front

What are surface currents?

Back

Surface currents are ocean currents that occur at the surface of the ocean, primarily driven by wind and influenced by the Coriolis Effect.

Front

What are deep ocean currents?

Back

Deep ocean currents are large-scale movements of water that occur below the surface, driven by differences in water density, temperature, and salinity.

Front

Explain the role of nutrients in marine ecosystems.

Back

Nutrients are essential for the growth and survival of marine organisms, forming the base of the food web and supporting diverse marine life.

Front

What is the relationship between air pressure and wind movement?

Back

Air moves from areas of high pressure to areas of low pressure, creating wind.

Front

What are the two types of ocean currents?

Back

The two types of ocean currents are surface currents and deep currents.
