one of several competing scientific models that all seem equally successful in explaining the nature of life on Earth
Explanation:
- The theory of evolution is one of the several competing scientific models that all seems to successfully explain the nature of life on earth.
- A theory is usually drawn from careful observation of scientific investigation.
- Theories generally provides explanation into a phenomenon that occurs in nature.

Answer:
The height reached by the material on Earth is 91 km.
Explanation:
Given that,
Mass 
Radius = 1821 km
Height 
Suppose we need to find that how high would this material go on earth if it were ejected with the same speed as on Io?
We need to calculate the acceleration due to gravity on Io
Using formula of gravity

Put the value into the formula


Let v be the speed at which the material is ejected.
We need to calculate the height
Using the formula of height

Using ratio of height of earth and height of Io


Put the value into the formula





Hence, The height reached by the material on Earth is 91 km.
