What happens to salinity if the rate of evaporation is greater than precipitation? Why?​
malfutka [58]

Answer:

Answer:

Explanation:

What happens when water's salinity increases?

A combination of high salinity and low temperature makes seawater so dense that it sinks to the bottom of the ocean and flows across ocean basins as deep, slow currents.

What happens to local salinity when evaporation rates increase?

Salinity is the saltiness of seawater. Salinity is measured by the concentration of grams of salt per kilogram of water. ... What happens to local salinity when evaporation rates increase: Rises 5.

How is salinity related to evaporation and precipitation?

Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.

Form a hypothesis about the relationship between vegetable mass and salinity of the solution
mihalych1998 [28]

Answer:

HYPOTHESIS: IF the salinity of the solution decreases, THEN the vegetable mass increases.

Explanation:

Hypothesis, in an experiment, is a testable explanation or prediction made to solve an observed problem or answer a question. It shows how one variable called independent variable affects another variable called dependent variable. It is usually written in the "IF, THEN" format.

In this case, the question states that there is a relationship between vegetable mass and salinity of the solution. This means that the question has been asked that "Why is the vegetable's mass affected by salinity of a solution". Hence, a hypothesis can read:

IF the salinity of the solution decreases, THEN the vegetable mass increases.
