a. evaporation
b. transpiration
c. infiltration
d. precipitation

1. which of the following is not a part of the water cycle?

1. the average salinity of seawater is about

a. 1%
b. 10%
c. 35%
d. 70%

1. the largest ocean on earth is the

a. indian ocean
b. atlantic ocean
c. arctic ocean
d. pacific ocean

1. the main salt found in seawater is

a. sodium chloride
b. potassium nitrate
c. calcium carbonate
d. iron oxide

1. what happens to salinity when seawater evaporates?

a. it increases
b. it decreases
c. it stays the same
d. it disappears

Explanation:

1. Infiltration is the process of water moving through soil into groundwater.
2. Transpiration is the process by which plants release water vapor into the air.
3. Photosynthesis is a process in plants to produce food using sunlight, not part of the water cycle. The water cycle includes evaporation, condensation, and precipitation.
4. The average salinity of seawater is about 3.5% (or 35‰).
5. The Pacific Ocean is the largest ocean on Earth.
6. Sodium chloride (common salt) is the main salt in seawater.
7. When seawater evaporates, the amount of salt remains while the water (solvent) decreases, so salinity increases.

Answer:

1. A. Infiltration
2. B. Transpiration
3. B. Photosynthesis
4. C. 35‰
5. D. Pacific Ocean
6. A. Sodium chloride
7. A. It increases
