How many scientists agree that global warming is real?
The overwhelming majority of scientists agree that global warming is real. Multiple studies have shown that around 97 of climate scientists support the consensus that human activities are causing global warming.
What do scientists believe is causing the temperature of earth a tmosphere to change?
Scientists believe that the increase in greenhouse gases, particularly carbon dioxide, from human activities such as burning fossil fuels, deforestation, and industrial processes is the main cause of the Earth's atmosphere warming. This leads to the greenhouse effect, where these gases trap heat in the atmosphere, causing the planet's temperature to rise.
What do scientists think is causing the earth's atmospheric temperature rise?
Scientists think that human burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity (which releases carbon dioxide (CO2)), is causing the atmospheric temperature rise.
How do scientists believe that continents move?
Scientists believe that continents move due to the process of plate tectonics. This theory explains that the Earth's outer shell is divided into several plates that float on the semi-fluid mantle below. These plates move over time, causing the continents to drift apart or come together.
How do scientists think the continents?
Scientists think that the continents were once part of a supercontinent called Pangaea that started breaking apart about 200 million years ago through the process of plate tectonics. This movement of the Earth's crustal plates continues to this day, causing the continents to drift apart.
What do scientists do to make sure that changes in the manipulated variable are causing the changes in the responding variable?
ask your teacher
Why is using two manipulated variables in an experiment would not work?
Using two manipulated variables in an experiment can make it difficult to determine which variable is actually causing a change in the outcome. This can lead to confounding variables and make it challenging to draw clear conclusions about the relationship between the variables and the outcome. It's important to isolate and study one variable at a time to accurately understand its impact.
A variable of which a researcher is not aware but which might be causing changes in the response variable is called a variable?
lurking
Do scientists know exactly what's causing the ozone layer to disappear?
Yes, scientists know what is causing the ozone layer to disappear. It is the continues use of ozone depleting substances.
What principles of experimental design ensures that the explanatory variable and not some variable over which the experimenter has no control is causing observed changes in the res?
Control
What do scientists believe is causing the temperature of Earth's atmosphere to increase?
no one cares
When a researcher cannot tell which variable might be causing an observed effect in an experiment the variables are?
confounded
Why is advantageous for scientist to test only one variable at a time during an experiment?
If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.It is advantageous for scientists to test only one variable at a time during an experiment because if you change all variables at once, you will not be able to tell which variable is responsible for the observed results.
How long does it take for ascending paralysis to spread?
This is extremely variable, depending upon the condition causing the paralysis.
Why is it important to only have one variable in an experiment?
If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.
What is a controlable variable?
A variable which can be controlled by some other variables or some other parameters is known as controlled variable. A controlled variable is something that can be changed by the experimenter. It is also known as the independent variable. It is something that gives a measure by which to gauge everything else by. For example, if you were testing the effectiveness of a plant fertilizer the "control" would be a plant that is given no fertilizer at all. A controlled variable is the variable that stays the same through out the experiment meaning no changes to it.
What is the difference between causation and correlation and how can we determine if one variable is causing changes in another variable?
Causation refers to a direct cause-and-effect relationship between two variables, where one variable directly influences the other. Correlation, on the other hand, simply means that two variables are related in some way, but one does not necessarily cause the other. To determine if one variable is causing changes in another variable, researchers often use experimental studies where they manipulate one variable and observe the effect on the other. Additionally, controlling for other factors and using statistical analysis can help establish a causal relationship between variables.
