Ocean and Earth Science Flashcard

Front

What is the area of the ocean that contains most of the ocean's water but has very little marine life?

Back

Open ocean.

Front

What are currents that occur at or near the surface of the ocean called?

Back

Surface currents.

Front

Which of Earth's spheres protects us from the sun's intense heat and radiation?

Back

Atmosphere.

Front

What is a possible explanation for a set of observations or an answer to a scientific question called?

Back

Hypothesis.

Front

What phenomenon bolsters plankton growth in the ocean?

Back

Upwellings.

Front

Define 'littoral zone' in oceanography.

Back

The littoral zone is the part of a sea, lake, or river that is close to the shore.

Front

What is the primary driver of ocean currents?

Back

Wind is the primary driver of surface ocean currents.

Front

Explain the term 'hypothesis' in scientific research.

Back

A hypothesis is a proposed explanation for a phenomenon, which can be tested through experimentation.

Front

What is the difference between 'upwelling' and 'downwelling' in ocean currents?

Back

Upwelling brings nutrient-rich water to the surface, while downwelling involves the sinking of surface water.

Front

What role does the atmosphere play in Earth's systems?

Back

The atmosphere protects life on Earth by filtering harmful solar radiation and regulating temperature.
