Which composition layer contains most of the Earth’s mass? The lithosphere is also known as the “__ sphere.” The asthenosphere is also known as the “__ sphere.” The mesosphere is also known as the “__ sphere.” The lithosphere is made of __ parts. Name them. Which layer of the mantle is included in the asthenosphere? Can it move? The Earth’s core is made mostly made of ____?
Could you solve the mystery? North American South American
Take a look at the continents! South America Africa South America It shows how the continents would fit together if you moved the Atlantic Ocean.
Lithosphere15–300km Asthenosphere 250km Outer Core is the liquid layer of the Earth’s core that lies beneath the mantle and surrounds the inner core. Inner Core The inner core is the solid, dense center of our planet that extends from the bottom of the outer core to the center of the Earth, some6,378 km beneath the surface. Outer core 2,200 km Mesosphere 2,550 km Inner core 1,228 km
