Which planet has the tallest volcano?

The most geologically active planet I know if Venus, which has constant eruptions which keep the crust of the planet looking very new. There are also a few moons of Jupiter, Io in particular that have similar processes going on. Io is the most volcanic body in the solar system it has 400 active volcanoes 10 of which are higher than Mt. Everest. Comment: Venus has the most volcanoes, but how active they are is still uncertain.


What evidence does the scientists have that proves the mantle is full of magma?

Volcanoes show that there is liquid rock. This must be from somewhere. Also, using SONAR, we can see what the rock is like - and we can tell it is liquid.

Is there life forms on mars and if there is what are they?

So far as we have been able to tell, there are currently no life forms on Mars - but more experimentation is needed, the possibility of it has not been ruled out. More sophisticated landers in the future may help to decide the question. And most scientists today are actually more interested in the question: "Wasthere ever life on Mars"?


How is the maars taught to perform its task?

it's not actually 'taught'. The scientists write a computer program to tell the rover what to do - and send the program by radio to Mars. The rover receives the program, and follows the instructions.
