<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>

Which of the following is true of the hydrologic cycle?
marissa [1.9K]

According to the research, the correct option is Most of the water that falls on the continents is derived from the oceans. It is true about the hydrological cycle.

<h3>What is the hydrological cycle?</h3>

It is the water cycle that allows water to pass from the earth's surface to the atmosphere so that it can then return to its liquid and solid phases. .

In this process, therefore, sublimation, evaporation and transpiration play an essential role where 70% of the earth's surface is covered by liquid water, of which 97% is salt water that forms the oceans.

Therefore, we can conclude that according to the research, the correct option is  Most of the water that falls on the continents is derived from the oceans. It is true about the hydrological cycle.

Answer:

In the last step of the scientific process when they compare their results.

Explanation:

The scientific process can be described of the following steps in order:

Starting with the observation, finding a point that asks a question which will be investigated, constructing a hypothesis that can be tested, testing the hypothesis and lastly comparing the results and starting over.

The example given in the question has a question to investigate, the students have a hypothesis. They test it and find out that the water sample can hold 20 amoeba which does not match their predictions. The students will check if their results match their predictions in the last step of the process when they compare their results with their hypothesis.

I hope this answer helps.
