What describes the outer core? Layers of Earth: Our Planet, the Earth is made up of different layers.Each layer of the Earth has unique properties. This layer of rock even flows like asphalt under a heavy weight. The thickest layer of the Earth is the mantleIf considering the core as two parts (Inner and Outer Core), then the mantle is the thickest single layer, located between the crust and the outer core. Tags: Question 2 . 3.inner core. The outer core is composed of iron and nickel and is completely liquid magma as there is little to no pressure in this section of the earth. It lies between Earth's dense, super-heated core and its thin outer layer, the crust. answer choices . gas. 1 See answer mercyrecto46 is waiting for your help. It starts a mere 30 kilometers (18.6 miles) beneath the surface. Tags: Question 3 . The crust is the thinnest of the four layers on Earth, and is only 1 percent of the whole Earth. It is about 8km thick in the ocean bed, which is … How many layers does the Earth have? the outer core. liquid. Layers of Earth. This liquid layer is approximately 2200 kilometres thick making it the second largest layer of the earth after the entirety of the mantle. The thickest layer of the earth 3. the inner core. The second layer of the Earth is the mantle. Like the layer below it, … pressure of the core is very high. Q. 30 seconds . the crust. Human life all exists on the crust of the Earth, as does the rest of known organic life. SURVEY . Made mostly of iron, magnesium and silicon, it is dense, hot and semi-solid (think caramel candy). The mantle is the largest layer of the Earth, 1800 miles thick. The upper mantle, along with the crust, makes up the lithosphere of earth, which is physically distinct from the layers lying below due to its low temperature high thickness. answer choices . 30 seconds . The outer core is half of the earth's third and last layer, the core. bulataoo bulataoo 1.Crust. the density increases the deeper you go into the Earth's layers. In 1692, Edmond Halley put forth the idea of a hollow Earth consisting of a shell about 500 miles (800 km) thick, two inner concentric shells and an innermost core. Q. Add your answer and earn points. It is the largest and thickest layer of earth. What is the thickest layer of the Earth? This layer of Earth … SURVEY . Measuring 1,800 miles in depth, the mantle is the thickest part of the Earth’s layers, making up a whopping 84% of Earth’s total volume. the mantle. The crust’s thickness ranges in measurement from only 5 to 70 km thick, depending on location. What is the relationship between density and depth of material below Earth's surface? solid. Part of the core made of solid 5. It is the innermost layer of the Earth 4. What is the outermost layer of Earth? What is the largest/thickest layer of Earth? The mantle is composed of very hot, dense rock. The crust is an outer solid layer and this is where all life exists on the earth’s surface, including us, animals, mountains, sea, and soil. 2.mantle. crust. viscous.
