Slowly, deep underground
The igneous rock gabbro is coarse grained and non-vesicular. Both characteristics show that it is an intrusive igneous rock. Intrusive igneous rocks are formed below Earth's surface and slowly (because they're underground). When rocks are intrusive, they are are non-vesicular (no air pockets) because the air has had the time to escape because of the slow cooling time period. Intrusive rocks are also coarse because crystals had the time to form in the rock during that longer cooling time.
Ps. extrusive igneous rocks form rapidly at Earth's surface and basically have tge opposite characteristics for the opposite reasons (ex: vesicular cause air had little time to escape)
At the point when the measure of the surface region with respect to volume builds, the rate of weathering increments. Weathering is the breakdown of rocks at the Earth's surface, by the activity of water, extremes of temperature, and natural action. It doesn't include the expulsion of shake material.
Tsunamis are created when a maginutde of 5.3 or higher earthqauke occurs by a large body of water, the shaking of the ground causes the water to move or the vibration, therfore causing a tsunami . Also California would have a tsunami after a earthqauke if it was big enougth , and if it was close enough to the shore.
