Which best explains why so little of the water on Earth is available for human use?

• 97% of total water on Earth is freshwater, and most of the remaining 3% is salt water in the ocean basins.

• 97% of total water on Earth is salt water, and most of the remaining 3% is freshwater frozen in ice caps and glaciers.

• 97% of total water on Earth is freshwater, and most of the remaining 3% is salt water found in underground aquifers.

• 97% of total water on Earth is salt water, and most of the remaining 3% is freshwater found in lakes, rivers, and ponds.

Which is the best reason for monitoring local water availability in the hydrosphere?

• to be prepared in case of drought

• to measure exact levels of well water

• to predict the best fishing ponds and lakes

• to determine the latest precipitation amounts

Which statement best compares the amount of water present on Earth today with the amount present millions of years ago?

• There is slightly more water on Earth today.

• There is significantly less water on Earth today.

• There is significantly more water on Earth today.

• There is about the same amount of water on Earth today.

If water is recycled in the atmosphere, which best describes why water availability on Earth is decreasing?

• An increase in precipitation is slowly reducing freshwater reservoirs.

• Due to an increase in Earth’s temperature, evaporation rates continue to decrease reducing liquid water on the surface.

• Earth’s freshwater continues to become more polluted, reducing the supply of freshwater safe for humans to consume.

• Water is draining off the Earth at an alarming rate.

Which allows a variety of life to thrive in estuary ecosystems?

• the temperature fluctuations

• the mixture of freshwater and salt water

• the dissolved nutrients that enter from nearby farms

• the constant movement of water that keeps the water cloudy

Which best explains why upwellings are beneficial to sea life?

• They bring warm waters to the surface.

• They bring needed nutrients to the surface to feed ocean life-forms.

• They help sea creatures move more quickly through strong currents.

• They create turbidity currents that muddy the water and hide sea creatures from predators.

Which best explains why exploration of the deep ocean floor is limited?

• The salinity in the deep ocean is too low for human life.

• The levels of oxygen in the deep ocean are too high for human life.

• The temperature on the deep ocean floor is too high for human life.

Which best describes an effect overfishing of large marine species has on the ocean ecosystem?

• Marine birds have less habitat areas.

• Smaller fish thrive without predators.

• Large marine fish reproduce at a faster rate.
