What is the thickness and depth of the outer core of the earth?
The Earth's outer core is about 2,266 kilometers, or 1,408 miles thick. It is composed of iron and nickel and is liquid.
Is outer core made of solid metal?
The Earth's inner core is solid metals and the outer core is liquid metals.
What is the outer core'?
The outer core is a layer of molten metal that surrounds the inner core. The outer core lies at a depth from 2900 km to 5150 km. It's composed of liquid iron and nickel along with small amounts of lighter elements, with temperatures ranging from 4,000 degrees C to 6,100 degrees C near the boundary with the inner core.The Earth's outer core:is composed primarily of liquid iron and nickelextends from a depth of 1,806 to 3,219 miles from the surfacecomprises 30.8 percent of Earth's masstemperatures range from 7,200-11,000 Fcontrols Earth's magnetic field which protects us from the sun's solar windsis in a liquid state
What part of the earth's core is the coldest?
The coldest part of the Earth's core is the outer core, specifically at its boundary with the mantle. Temperatures in the outer core can range from about 4,000 to 6,000 degrees Celsius, but the transition zone at the outer core-mantle boundary is relatively cooler compared to deeper layers. However, the inner core, despite being extremely hot, can have cooler areas at its outer edge, where it is solidified. Overall, the outer core is generally considered the coldest region of the core.
How do you use earths outer core in a sentence?
The various layers inside the earth range from solid rock, like the crust, to liquid metals, like the earth's outer core.
What is the depth of the otter core?
Outer* 2,890-5,150km
What is the actual size of earth's outer core?
The outer core lies at a depth from 2900 km to 5150 km.
What is the pressure range of the outer core?
the muppets
What is the thickness and depth of the outer core of the earth?
The Earth's outer core is about 2,266 kilometers, or 1,408 miles thick. It is composed of iron and nickel and is liquid.
What is the difference between the mantle and outer core of the Earth?
There are differences in chemistry (the mantle is mainly ultramafic rock--the outer core is metallic), in phase (the mantle is predominately solid--the outer core is liquid), in depth (the outer core is closer to the center of the Earth), and in density (the outer core is more dense).
What part of Earth's mantle is near the outer core?
The Earth comprises:-Continental crust: depth of 0-75 kilometres: Oceanic crust: depth of 0-10 kilometresUpper mantle: depth of 10-400 kilometresTransition region: depth of 400-650 kilometresLower mantle: depth of 650-2,890 kilometresD" layer: depth of 2,700-2,890 kilometresOuter core: depth of 2,890-5,150 kilometresInner core: depth of 5,150-6,370 kilometres
What is the depth earths outer core?
The Earth's outer core is a molten layer primarily composed of iron and nickel. Its outer boundary lies 2,890 kilometers beneath Earth's surface.
How thick is the outer core in km?
the outer core is 2300 km thick the inner core on the other hand is 1200 km thick.
Which of these describes the earth outer core?
The Earth's outer core is a liquid layer composed mainly of iron and nickel. It is responsible for generating the planet's magnetic field through convection currents. The outer core is situated below the mantle and extends to a depth of about 2,300 kilometers.
What is the range density within the outer core?
about 2,300 km
Is the temperature of the outer core higher or lower than ist melting point?
The temperature of the outer core is higher than its melting point. The outer core is mainly composed of liquid iron and nickel, which has a melting point higher than the temperature of the outer core due to the immense pressure at that depth.
Is outer core made of solid metal?
The Earth's inner core is solid metals and the outer core is liquid metals.
