The volcanic actvitty in the Cascades is driven by the Cascadia Subduction Zone, where two of Earth's tectonic plates meet. Of the coast of the Cascades the small Juan de Fuca Plate is colliding with and sliding under the North American Plate and into the mantle. This plate drags seawater and other volatiles with it. These seep into the superheated mantle, causing some of the semisolid rock to melt into magma. This magma then rises as it is less dense than the surrounding material. It eventually makes it to the upper crust, erupting from the resulting volcanoes.

No, Ceres does not have volcanic activity.
volcanic activity is when a volcano is active or has just started erupting.
Yes, the moon does have volcanoes, but they are practically dead. They have no volcanic activity.

The growth of the Hawaiian island chain is primarily due to the movement of the Pacific tectonic plate over a hotspot in the Earth's mantle. As the plate moves, volcanic activity at the hotspot creates new islands, with the oldest islands in the chain found in the northwest and the youngest in the southeast.

A significant impact to the planet from a large enough asteroid could cause volcanic eruptions.

Geothermal Radiation (underground heat) from near by volcanic activity.
No.Mountains are the result of continental drift an volcanic activity. Earthquakes are also the result of continental drift an volcanic activity. Thus the two go together but the earthquakes do not cause the mountains.
The volcanic and earthquake activity in the Pacific Northwest is mainly caused by the movement of the Juan de Fuca tectonic plate being subducted beneath the North American plate. This subduction process creates pressure and friction, leading to volcanic eruptions and seismic activity in the region.
