We've just planted a grafted avacodo tree (Hass) but it looks terrible with all it's leaves turning brown. So I checked the soil around it this morning and it was very moist about 6 inches down.

Volcanoes and earthquakes are seemingly very different geological events, yet they are actually closely related-both result from movements of Earth's crust.Earth's crust-the lithosphere-is composed of several major plates and many minor plates that change shape and position.onfidence votes 57.

Volcanic activity. Where tectonic plates meet, the Earthâs crust becomes unstable as the plates slide past each other, push against each other, or ride under or over one another. Earthquakes and volcanic eruptions happen at the boundaries between plates. Magma (molten rock) is less dense than the crust. It can rise to the surface through weaknesses in the crust, forming a volcano. Geologists study volcanoes to try to predict future eruptions. Volcanoes can be very destructive, but some people choose to live near them because volcanic soil is very fertile. Earthquakes
