GEOLOGY

Detailed explanation-1: -Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet’s mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption.

Detailed explanation-2: -Magma originates in the lower part of the Earth’s crust and in the upper portion of the mantle. Most of the mantle and crust are solid, so the presence of magma is crucial to understanding the geology and morphology of the mantle.

Detailed explanation-3: -Magma is found within the chemical layers of Earth: the crust, and upper mantle because the processes that occur in these locations create the circumstances in which rock can melt. The mechanical layers in which magma is found are around the lithosphere and its boundary with the asthenosphere.

Detailed explanation-4: -The outer core is the liquid largely iron layer of the earth that lies below the mantle. Geologists have confirmed that the outer core is liquid due to seismic surveys of Earth’s interior. The outer core is 2, 300 km thick and goes down to approximately 3, 400 km into the earth.

Detailed explanation-5: -Earth’s outer core is a fluid layer about 2, 260 km (1, 400 mi) thick, composed of mostly iron and nickel that lies above Earth’s solid inner core and below its mantle.
