Oceans

Front

What is upwelling?

Back

Upwelling is the process where deep, cold, nutrient-rich water rises to the surface, increasing the nutrient levels in the water.

Front

What effect do cold ocean currents have on climate?

Back

Cold ocean currents generally cool the air above them, leading to cooler coastal climates.

Front

What is the origin of cold ocean currents?

Back

Cold ocean currents generally originate from polar regions, specifically the North Pole and the South Pole.

Front

What is the origin of warm ocean currents?

Back

Warm ocean currents generally originate from the Equator.

Front

What is the primary factor that influences Earth's tides?

Back

The Moon has the greatest effect on Earth's tides due to its gravitational pull.

Front

What is a high tide?

Back

A high tide is the bulge of water on the side of the Earth closest to the Moon, resulting in higher water levels.

Front

What is a low tide?

Back

A low tide is the state of the tide when water levels are at their lowest, occurring on the side of the Earth opposite the Moon.

Front

What are neap tides?

Back

Neap tides occur when the gravitational forces of the Moon and the Sun are perpendicular to each other, resulting in lower high tides and higher low tides.

Front

What are spring tides?

Back

Spring tides occur when the Earth, Moon, and Sun are aligned, resulting in higher high tides and lower low tides.

Front

What is the Coriolis effect?

Back

The Coriolis effect is the deflection of moving objects, such as ocean currents, due to the rotation of the Earth.
