The magma chamber below the Yellowstone caldera. It's located in Yellowstone national park.
Answer:
inner core- solid hot rock
outer core- magma that suronds the inner core
The model demonstrates the differences between the types of tectonic plates and the resulting observations in the asthenosphere there are two foremost sorts of tectonic plates: Oceanic and Continental. Continental crust is often fashioned of granite and is typically referred to as sial because of a large amount of silica and aluminum gift. Continental crust is much less dense than the basaltic oceanic crust, sima, which is constructed from silica and magnesium. Due to the fact it's far denser, oceanic crust plunges beneath the continental crust. The department between the 2 layers is known as the Conrad Discontinuity.
Asthenosphere, a sector of Earth's mantle mendacity beneath the lithosphere and believed to be a whole lot hotter and more fluid than the lithosphere. The asthenosphere extends from about 100 km (60 miles) to about 700 km (450 miles) underneath Earth's floor. Cross-section of a tectonic plate.
It's miles a layer of stable rock where the intense pressure and warmth cause the rocks to flow like a liquid. The rocks in the asthenosphere are not as dense because of the rocks in the lithosphere. This allows the tectonic plates within the lithosphere to move around on the planet's floor.
The asthenosphere is the robotically weak and ductile vicinity of the upper mantle of Earth. It lies underneath the lithosphere, between approximately 80 and two hundred km below the surface, and extends as deep as seven-hundred km. But, the decreased boundary of the asthenosphere isn't always well described.

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.
Answer:
The seafloor is younger at the mid-ocean ridge, and as it gets further away from it is older and older.
Explanation:
The seafloor and its characteristics is one of the best evidence when it comes to the theory of plate tectonics. This was first noticed by Alfred Wegener and later by any other scienticsts that have been interested in this theory. Basically, the evidence lies in the fact that the seafloor is the youngest at the active mid-ocean ridge, and the further it is from it it gets older and older, with the oldest seafloor being found at the subduction zones.
The reason for this is the manner in which the seafloor forms. The high activity in the mantle below manages to break the crust of a preexisting plate and divide it. It pushes enormous amouns of magma toward the surface constantly for millions of years. The magma quickly solidifies and creates new seafloor as it gets in touch with the water. The magma that comes through pushes the already consolidated one aside and the process goes on for millions of years.
