You are watching a televised debate on evolution. one of the participants repeatedly states that evolution is a "scientific theory," and as such is unsupported by any evidence. what is wrong with this statement?

Answer : Scientific theories are rigorously supported by numerous studies, and are hypotheses that, even up till date, have never been disproved.

Explanation:

Scientific theory can be explained as a theory that was highly supported by facts. This means that , it is continuously or repeatedly confirmed by observation and experiment by scientists.

Evolution can be described as changes that occur in the heritable characters over a period of time. This usually occurs through natural selection.

In this case, evolution is known to be a scientific theory, because it involved careful observations and confirming experiments by scientists.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.
