What is planet earth made up of?

Answer 1

The Earth is made out of many things. Deep inside Earth, near its center, lies Earth's core which is mostly made up of nickel and iron. Above the core is Earth's mantle, which is made up of rock containing silicon, iron, magnesium, aluminum, oxygen and other minerals. The rocky surface layer of Earth, called the crust, is made up of mostly oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium. Earth's surface is mainly covered with liquid water and its atmosphere is is mainly nitrogen and oxygen, with smaller amounts of carbon dioxide, water vapor and other gases.

Answer 2

Earth's surface is 70% water. The overall composition of the Earth is dominated by the elements iron (Fe), oxygen (O), silicon (Si), magnesium (Mg), nickel (Ni) and sulfur (S). This is because most of the mass of the Earth occurs within the mantle which is composed largely of the ferromagnesium silicate minerals olivine and pyroxenes. The core of the Earth is largely composed of iron and nickel. The crust of the Earth mainly comprises the minerals plagioclase, quartz and hornblende and is dominated by the elements oxygen, silicon, aluminium, iron, calcium, sodium, and potassium. Earth's atmosphere is roughly (by volume) 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.038% carbon dioxide, and trace amounts of other gases. Air also contains a variable amount of water vapor, on average around 1%.

Answer 3

Earth's mass is approximately 5.97×1024 kg (5,970 Yg). It is composed mostly of iron (32.1%), oxygen (30.1%), silicon(15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%), with the remaining 1.2% consisting of trace amounts of other elements.

Answer 4

Planet Earth is composed of several layers, including the solid inner core, liquid outer core, mantle, and crust. The crust is made up of various materials such as rocks, minerals, and organic matter. The Earth's composition also includes elements like iron, oxygen, silicon, and magnesium.

Answer 5

That's complicated. To start with, the inner core is made out of solid iron. The outer core is made out of liquid iron. Then it is mantle rock all the way to the surface layer, which is rock.

Answer 6

nitrogen ~79%, oxygen ~20%, (argon, carbon dioxide, neon, and other trace gases) ~1%

Answer 7

Oxygen 46.60 , silicon 27.72 , aluminium 8.13, calcium 3.63 , sodium 2.83 , potassium 2.59 , magnesium 2.09 , others 1.41

Answer 8

earth is made from rock
