A standard for comparison that helps to ensure that the experimental result is caused by the condition being tested is the control.
<u>Explanation:</u>
In an experiment, we need to use a reference or standard term with which we compare our obtained results for better accuracy and precision. So there will several conditions or boundary conditions that need to include in those experiments to prevent the experiment from having a fallback or repair.
Among these several conditions, some of the conditions are mostly given to compare with the conditions occurred during the running of the experiment. And if any case, there is any change in those conditions with respect to standard conditions during the running of the experiment, then the experiment should be stopped.
So, these conditions which are standard comparison and helps to ensure that the experimental result is caused by the condition being tested and not anything else is termed as control.
Answer: All igneous rocks the basis of the rock cycle is formed by plate tectonics. ... This movement from igneous to sedimentary back to igneous is a major part of the rock cycle. The heat from the mantle that fuels plate tectonics causes both igneous and sedimentary rocks to be turned into metamorphic rocks.

Answer:
45 m
Explanation:
From the question given above, the following data were obtained:
Mass (m) = 0.5 kg
Initial height (h₁) = 30 m
Initial potential energy (PE₁) = 20 J
Final potential energy (PE₂) = 30 J
Final height (h₂) =?
From:
PE = mgh
PE / h = mg = constant
Thus,
PE₁ / h₁ = PE₂ / h₂
With the above formula, we can obtain the final height of the bird as follow:
Initial height (h₁) = 30 m
Initial potential energy (PE₁) = 20 J
Final potential energy (PE₂) = 30 J
Final height (h₂) =?
PE₁ / h₁ = PE₂ / h₂
20 / 30 = 30 / h₂
Cross multiply
20 × h₂ = 30 × 30
20 × h₂ = 900
Divide both side by 20
h₂ = 900 / 20
h₂ = 45 m
Therefore, the final height of the bird is 45 m.
