Unit 3 Earth's Hydrosphere | Test Review

Which describes the hydrosphere?

• all of Earth’s organisms and the environments in which they live
• a layer of Earth’s atmosphere made up primarily of concentrated ozone
• all of the water in Earth’s oceans, lakes, seas, rivers, and glaciers, plus the water in the atmosphere

The water cycle describes the movement of the water of Earth. About 97% of the water of Earth is the salt water found in the oceans while the remaining 3% is fresh water. Where would the majority of the freshwater on Earth be found?

• groundwater and aquifers
• swamps and wetlands
• ice caps and glaciers
• lakes and rivers

Which is true about most of the freshwater on Earth?

• It is abundant.
• It is inaccessible.
• It is underground.
• It is in the atmosphere.

What percentage of earths water is salt

• 3%
• 97%
• 70%
• 100%

How is the size of Charlotte's population related to the availability of water in the area?

• As the population increases, water availability increases.
• As the population increases, water availability decreases.
• As the population decreases, water availability decreases.

Which best describes the importance of an aquifer?

• It holds uncontaminated ground water for human consumption.
• It supplies all water for lakes and rivers.
• It provides water for oceans.

Which is an area of land that all drains to one place?

• river
• aquifer
• reservoir
• watershed/river basin

Estuaries are important because they:

• provide shelter for young organisms
• have LOTS of nutrients
• filter out pollution from the ocean
• all of the above

wind-driven process in which nutrient-rich, denser, colder water moves to the surface

• upwelling
• downwelling
• phytoplankton
• hydrothermal vents

a fissure in a planet's surface from which geothermally heated water issues. Hydrothermal vents are commonly found near volcanically active places, areas where tectonic plates are moving apart, ocean basins, and hotspots

• hydrothermal vents
• estuary
• open ocean
• photic zone
