A local farm experiences significant drought over a 2-year period. A temporary solution for the lack of water is to dig another well closer to the fields to water crops. Two years before, in a similar situation, the water table was reached at 15 feet below the ground. Which is necessary for the well to supply water to the crops?

• The well needs to be dug to 13.5 feet.

• It is not necessary to find the water table when digging a well.

• The well should be dug to more than 15 feet to find the water table.

• The well should be less than 13 feet deep.

Which best describes the water distribution in an estuary?

• The saltwater is closer to the surface than the freshwater.

• The freshwater is closer to the surface than the saltwater.

• The saltwater is found closer to the bank, and the freshwater is found closer to the center.

• The freshwater is found closer to the bank, and the saltwater is found closer to the center.

The diagram below shows the surface winds and water in a coastal area. Which best describes this process?

• density currents

• downwelling

• spring tide

• upwelling

Which best explains why there is a greater concentration of oxygen located near the ocean’s surface?

• Sunlight warms the ocean’s temperature and stimulates oxygen production near the surface.

• Plankton produces excess amounts of nutrients that remove oxygen levels from the atmosphere.

• Marine life gives off oxygen instead of carbon dioxide, which makes the ocean water rich in oxygen.

• Plants, which release oxygen, live near the surface of the ocean, where they receive large amounts of sunlight.
