part a: the water cycle (multiple choice)

1. what are the main processes of the water cycle?

a) evaporation, condensation, precipitation, collection
b) melting, erosion, sedimentation, compaction
c) respiration, photosynthesis, transpiration, decomposition
d) radiation, conduction, convection, reflection

1. which process involves water vapor cooling and changing into liquid droplets?

a) precipitation
b) condensation
c) evaporation
d) infiltration

1. what is the term for water that soaks into the ground and replenishes aquifers?

a) runoff
b) infiltration
c) transpiration
d) accumulation
part b: the hydrosphere (multiple choice)

1. the hydrosphere includes:

a) only oceans and seas
b) all of earths water in any form (liquid, solid, gas)
c) only rivers and lakes
d) only groundwater

1. about what percentage of earths water is freshwater?

a) 3%
b) 10%
c) 25%
d) 50%

1. where is most of earths freshwater stored?

a) rivers
b) lakes
c) glaciers and ice caps
d) groundwater
part c: hydrothermal vents (multiple choice)

1. hydrothermal vents are typically found:

a) on sandy beaches
b) in the middle of deserts
c) along mid - ocean ridges on the seafloor
d) inside freshwater lakes

1. what makes hydrothermal vent ecosystems unique compared to most others on earth?

a) they depend on sunlight for energy
b) they rely on chemosynthesis instead of photosynthesis
c) they only support fish and no other organisms
d) they exist only near coastlines

Explanation:

1. The water - cycle processes include evaporation (water turning to vapor), condensation (vapor turning to liquid), precipitation (falling of liquid or solid water), and collection (water gathering in bodies).
2. Condensation is when water vapor cools and changes into liquid droplets.
3. Infiltration is the process by which water soaks into the ground and replenishes aquifers.
4. The hydrosphere encompasses all of Earth's water in any form (liquid, solid, gas).
5. Approximately 3% of Earth's water is freshwater.
6. Most of Earth's freshwater is stored in glaciers and ice - caps.
7. Hydrothermal vents are typically found along mid - ocean ridges on the seafloor.
8. Hydrothermal vent ecosystems are unique because they rely on chemosynthesis instead of photosynthesis as they are in the deep sea with no sunlight.

Answer:

1. A. Evaporation, condensation, precipitation, collection
2. B. Condensation
3. B. Infiltration
4. B. All of Earth's water in any form (liquid, solid, gas)
5. A. 3%
6. C. Glaciers and ice caps
7. C. Along mid - ocean ridges on the seafloor
8. B. They rely on chemosynthesis instead of photosynthesis
