2025 Earth's Layers- Aiden Childs

Outer Core

The liquid layer of Earth’s core that is beneath the mantle and surrounds the inner core.

Fun Facts The liquid layer of Earth’s core that is beneath the mantle and surrounds the inner core. The churning motion of the liquid iron and nickel is responsible for generating Earth's magnetic field through a process known as the geodynamo.

Inner Core

33% of Earth’s mass At the center of the earth is the solid inner core. The inner core is made of iron with some nickel and very small amounts of oxygen, silicon, aluminum & magnesium.

Inner Core

• It's a solid ball of metal. The inner core is a solid sphere made mostly of iron-nickel alloy. Its rigidilty was confirmed 1971.
• It's incredibly hot, but it's solid its temperature reach up to and estimated 5,400 and 5,700 C.

Lithosphere

The outermost rigid layer of the earth. It is made of the crust and the rigid upper part of the mantle. The lithosphere is divided into pieces called tectonic plates. (Litho – means stone or rock & sphere means globe or ball)

Fun Facts

• The lithosphere is Earth's hard, outer shell, made of the crust and the upper part of the mantle
• The lithosphere is Earth's rigid outer layer, and fun facts include that it is broken into moving tectonic plates, with continents like North America and Europe drifting apart at about one to two inches per year

Continental Crust

Continental crust is the thick, less dense, and rigid outermost layer of Earth that forms the continents and shallow ocean shelves

Fun Facts

• Continental crust covers 41percent of the Earth's surface, though a quarter of that area is under the oceans
• Continental crust is the Earth's less dense, granitic layer that forms landmasses and is much older than oceanic crust, with some rock formations dating back over 4 billion years

Moho

A fun fact about the asthenosphere is that despite being solid rock, it flows incredibly slowly, like a super-thick syrup, which allows the rigid tectonic plates above it to move

Fun Facts

• the Moho is so deep that humans have never successfully drilled to it
• The 'Moho Discontinuity' is the boundary between the crust and mantle. It has been named so as it was discovered by Croatian Seismologist Andrija Mohorovicic
• What is the Moho? How was it Discovered? (2018_Educational)

Asthenosphere

a layer of mostly solid rock that flows and oozes like a milkshake. The lighter plates of the lithosphere float on the asthenosphere. (Asthenos means “weak”)

Fun Facts

• The asthenosphere is a "weak" layer of the Earth's upper mantle, located roughly 100 to 400 kilometers below the surface, that is crucial for plate tectonics because its solid, yet plastic and partially molten rock flows slowly
• A fun fact about the asthenosphere is that despite being solid rock, it flows incredibly slowly, like a super-thick syrup, which allows the rigid tectonic plates above it to move

Upper Mantle

The upper mantle is the uppermost layer of Earth's mantle, divided into two parts

Fun Facts

The upper mantle is on average 200 to 250 miles thick. The mantle's composition is higher in magnesium here than in the crust The Earth's mantle is a flowing, solid rock layer that makes up about 40% of the planet's volume, with fun facts including its plastic-like flow, the fact that it can generate deep earthquakes, and the existence of areas where the mantle is exposed on the ocean floor.

Lower Mantle

the Earth's largest layer, extending from 670 km to 2,890 km deep, and is composed of hot, solid rock under immense pressure

Fun Facts

• The lower mantle is a solid layer beneath Earth's crust, but it is hotter and denser than the upper mantle due to intense pressure
• The lower mantle extends from about 660 to 2,890 kilometers below the surface, makes up 56% of Earth's volume, and is composed of solid, dense, and hot rock despite its high temperature due to immense pressure

Oceanic Crust

Oceanic crust is the thin, dense, basaltic layer of the Earth's tectonic plates that underlies the oceans

Fun Facts

• Oceanic crust is the dense, basaltic layer of the Earth's lithosphere that lies beneath the oceans
• Oceanic crust is the denser, thinner crust that forms the seafloor, mainly composed of basalt. It is constantly being created at mid-ocean ridges and recycled back into the mantle at subduction zones, which is why the oldest oceanic crust is only about 200 million years old

Mesosphere

Beneath the asthenosphere, it is the strong lower part of the mantle. It reaches from the bottom of the asthenosphere to the Earth’s core

Fun Facts

• The mesosphere is the layer of Earth's atmosphere where most meteors burn up, creating visible "shooting stars"
• Incoming meteors burn up in the mesosphere due to friction with its gases, protecting the Earth's surface from impact. An estimated 40 tons of meteors are incinerated here every day
