Hydrosphere and Atmosphere

Which BEST characteristics of the ocean MOST likely helps to maintain the temperatures of Earth?

• depth of the ocean

• density of ocean water

• evaporation of the ocean water

Which is statement is TRUE when cold and warm ocean water travel around the world?

• The current will become cooler, causing it to become less dense and rise.

• The current will become warmer, causing it to become less dense and sink.

• The current will become warmer, causing it to become more dense and rise.

• The current will become cooler, causing it to become more dense and sink.

Which of the following causes ocean currents?

• acidity of water

• density of water

• turbidity of water

• viscosity of water

How does Coriolis effect impact ocean currents?

• It causes warm surface currents to flow towards the equator and cold surface currents to flow towards the equator.

• It causes warm surface currents to flow away from the equator and cold surface currents to flow towards the equator.

• It causes warm surface currents to flow away from the equator and cold surface currents to flow away from the equator.

• It causes warm surface currents to flow towards the equator and cold surface currents to flow away from the equator.

What causes ocean currents to continue to circulate around the world?

• topography of ocean floor

• rotation of the Earth on its axis

• different densities of ocean water

Which causes the continues movement of ocean water to the sides as well as the circulation patterns as shown in the map?

• Sun's tidal effect

• Coriolis effect

• density differences

• temperature differences

Which statement best describes the ozone layer of Earth?

• It forms a magnetic field in the mesosphere of Earth.

• It increases the amount of nitrogen in the troposphere of Earth.

• It helps reduce the amount of ultraviolet radiation reaching the surface of earth.

• It prevents the formation of severe storms in the stratosphere of Earth.

Which layer of the atmosphere has the highest density of gas molecules?
