O Europa had many icy comets crash into the surface bring water to the moon and melting the water as it fell into the core. O Furopa formed with an unusual amount of liquid water in the core and the coldness of space wasn't able to freeze it. O upiter's strong gravitational force is causing Europa to flex in its orbit, leading to an increase in internal heating. O Europa's close proximity to Jupiter puts it into a gravitational tug-of-war with Jupiter's targest moon Ganymede. Question 10 How was Neptune discovered?
