How does the rate of groundwater flow compare with that of ocean currents or river currents? Choose one: A. The rate of groundwater flow is faster than that of surface-water currents. B. The rate of groundwater flow can be faster or slower than that of surface-water currents, depending on conditions. C. The rate of groundwater flow is about the same speed as that of surface-water currents. D. The rate of groundwater flow is slower than that of surface-water currents.

A. The rate of groundwater flow is faster than that of surface-water currents

Explanation:

A velocity of 1 foot per day or greater is a high rate of movement for ground water, and ground-water velocities can be as low as 1 foot per year or 1 foot per decade. In contrast, velocities of streamflow generally are measured in feet per second.

Horizontal movements are called currents, which range in magnitude from a few centimetres per second to as much as 4 metres (about 13 feet) per second. A characteristic surface speed is about 5 to 50 cm (about 2 to 20 inches) per second.

An ocean current is any more or less permanent or continuous, directed movement of ocean water that flows in one of the Earth's oceans. The currents are generated from the forces acting upon the water like the earth's rotation, the wind, the temperature and salinity differences and the gravitation of the moon
