The Ozone layer is the the atmospheric region called the stratosphere, and shields us from harmful ultraviolet B radiation that comes from the sun.
Which are best answers?
No - Ozone holes can be hole-shaped. - Actually the ozone holes are not actually holes, but an area where the ozone has been depleted or thinned.
Yes - Ozone holes allow ultraviolet light to reach the Earth's surface. - When ozone levels decrease, it allows UVB radiation to pass through and our surface is exposed.
No- Ozone holes don't have any ozone in them. - Ozone holes have lower levels of ozone in that area of the stratosphere.
Yes - Chlorofluorocarbons make an ozone hole larger. This is called the greenhouse effect. When we warm the earth's surface with these types of gases, they can trap energy from the sun. This makes it warmer on earth's surface. There has been a scientific link between CFC gasses and ozone depletion.
Yes - There is always just one ozone hole in the Earth's atmosphere. - The ozone hole forms over Antarctica because its winter allows the atmosphere to get cold enough for nacreous clouds to form in the ozone layer.
No - Ozone holes have more ozone than usual. - Ozone holes are areas where the ozone levels are depleted.
When participants change their behavior based on perceived expectations from the observer, it is called observer-expectancy effect.
<h3>What is the observer-expectancy effect in psychology?</h3>
The experimenter may gently convey to the participants their expectations for the study's outcome, leading them to change their conduct to match those expectations.
<h3>When does the research hypothesis knowledge of observers affect what they record?</h3>
When an observer's understanding of the proposed theory affects how they record their observations Participants who alter their behavior in response to perceived expectations from observers are said to be When individuals alter their actions in response to another person's presence.
<h3>How might cognitive bias be introduced into a study by the experimenter?</h3>
There are various ways the experimenter can add cognitive bias into a study. The experimenter may quietly convey to the participants their expectations for the study's conclusion, leading them to change their behavior to match those expectations. This is known as the observer-expectancy effect.
<h3>What is Vroom Expectancy Theory (VET)?</h3>
One of the theories relating to the process of motivation is Vroom's Expectancy Theory. It is predicated on the notion that people think that their efforts will result in the consequences they want. The person believes they can perform because of their experience. Finally, they focus their efforts on results that will help them achieve their goals.
