Yes, they are partly caused by gravity.

Gravity speeds them up.
not sure work it out your self you brat
volcanoes and avalanches
Global warming is unlikely to cause avalanches directly. They are usually caused by runoff from heavy rain and intense storms. Global warming is expected to cause more intense storms and could therefore be an indirect cause of avalanches.

Avalanches are caused when a big impact of noise strikes. This is because sound vibrates objects and therefore vibrates mounds of snow, causing them to tumble down.
The Rocky Mountains are very steep, and avalanches are common as a result.

Tidal Currents are caused by the gravity of the Moon.
Avalanches occurs when huge snow masses become loose and flow downhill. This is caused by many factors including temperature, vibration, sloppy angle and so much more.
Earth's tides are caused by the Moon's gravity (in combination with the Sun's).
