Moderately dense forest, whose canopy density is between 40% and 70%
Explanation:
You can distinguish between correlation and causation and eliminate confounding variables by using random assignment. Experiments often create contrasts between a control group and one or more treatment groups as a crucial part of the scientific method.
<h3>When is random assignment appropriate in an experiment?</h3>
In general, whenever it is ethically feasible and appropriate for your research topic, random assignment should always be used in trials. Both random sampling and random assignment are crucial ideas in research, but it's critical to recognize their distinctions.
<h3>Is it moral to choose participants for an experiment at random?</h3>
Random assignment cannot be used to evaluate risky or unhealthy behaviour. For instance, it would be unethical to assign volunteers at random to one of the two groups and urge them to consume huge amounts of alcohol as part of an experiment on heavy drinkers versus social drinkers.

Answer:
There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection. Let's look at each of these stages.
Evaporation: This is when warmth from the sun causes water from oceans, lakes, streams, ice and soils to rise into the air and turn into water vapour (gas). Water vapour droplets join together to make clouds!
Condensation: This is when water vapour in the air cools down and turns back into liquid water.
Precipitation: This is when water (in the form of rain, snow, hail or sleet) falls from clouds in the sky.
Collection: This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Most will infiltrate (soak into) the ground and will collect as underground water.
The water cycle is powered by the sun's energy and by gravity. The sun kickstarts the whole cycle by heating all the Earth's water and making it evaporate. Gravity makes the moisture fall back to Earth.

15 pages, wow. Make your punctuation narks larger than the font. When you are talking about a certain topic, take a long time to explain it. Instead of doing a short paragraph, do like 3 paragraphs on that topic.
