Answer and Explanation: This is true that theories do change or get replaced overtime. We all know that in any scientific investigation the scientist put forth the theories which are basically the ideas explaining something particular. We also know that the world is experiencing constant changes and those changes could be of Technology or of overall world order so, whenever a scientist gives us the theory, that theory is made according to the situations and environment of that particular time and in future with the passage of time and with the advancement of Technology and other variables, scientist do need to re-evaluate theories. They either make some positive changes keeping in view the changing circumstances of the current situation or discard the theory altogether depending on its nature. The name research itself indicate that scientists research the already searched idea and in that way the New theory which comes after the modification of old theory or altogether the new theory takes place of the old one.

Answer:

Sample Response: Theories may be changed over time as new information is discovered or new technologies are developed. New developments lead to changes in experimental methods, which provide information that may or may not support the existing theory. If the theory is still supported, it may be updated. If it is not supported, but the results are true and relevant, the theory may be replaced

Which of the following explains how movement of material within earth causes volcanic eruptions
EleoNora [17]

The following choices are provided;

One plate moves below the other due to the movements in the inner core.

One plate moves below the other due to the movements in the mantle.

A plate slides past another due to the movements in the inner core.

A plate slides past another due to the movements in the mantle

The answer is; One plate moves below the other due to the movements in the mantle.

It is common that such convergent boundaries have a cascade of volcanic ranges. This is because as the oceanic plate moves below the continental plate the pressure and high temperatures cause the rock to melt and become magma. The magma makes it way up the crust through fissure and erupts.
