Because iron is dense - a small volume or amount weighs a lot compared to other materials.
With a very sizable iron core and a (by comparison) wafer-thin crust, I doubt that the earth's crust even approximates a full percentage point.

The 2 types of the Earth's crust are the ContinentalCrust and the Oceanic Crust. The Continental Crust is made of granite and the Oceanic crust is made of basalt.
If you're asking how much of the earth is in the crust layer, less than one percent. If you're asking what it's composition is:SiO2:60.6Al2O3:15.9CaO:6.4MgO:4.7Na2O:3.1Fe as FeO:6.7K2O:1.8TiO2:0.7P2O5:0.1
The five most abundant elements in Earth's crust by volume and listed here as a percentage of the total volume of the crust are:# Oxygen--47% # Silicon--28% # Aluminum--8% # Iron--5% # Calcium--4%suck on mah sack
% of volume = 100*(volume of substance that you are interested in)/(total volume) % of mass = 100*(mass of substance that you are interested in)/(total mass).
The formula for percent by volume (% v/v) is: (Volume of solute / Volume of solution) x 100 The formula for percent by mass (% w/w) is: (Mass of solute / Mass of solution) x 100

No, copper does not have more volume than iron for the same weight or mass. Copper is denser than iron, so a given mass of copper will have a smaller volume than the same mass of iron.
Percent of an objects mass is expressed in terms of its weight. Percent of an objects volume is expressed in terms of its size.
The four elements that make up 95 percent of the Earth's mass are oxygen, silicon, iron, and magnesium. These elements are abundant in the Earth's crust and core, contributing to its overall composition.
Percent per mass is exprimed in g/Kg, mg/kg, µg/kg, etc. Ex.: An ore contain 10 mg gold/kg ore. Percent per volume is exprimed in volume to volume. Ex.: Vodka contain 40 volumes of ethanol/100 volumes of liquid.

Density is mass divided by volume. If we assume the mass of the iron and the cotton is the same, you will find that the iron will occupy less space (less volume) than that of the cotton. The value of a mass divided by a small volume is higher than the value of the same mass divided by a larger volume. If we assume the volume of both the iron and the cotton is the same, you will also find that the mass of the iron will be higher than the mass of the cotton. The value of a large mass divided by a volume is larger than the value of a small mass divided by the same volume. In both assumptions, the value of mass divided by volume for the iron is higher than the value of mass divided by volume for the cotton. Since density is mass divided by volume, the density of iron is therefore higher than the density of cotton.
The total volume of Earth's crust is estimated to be around 1% of the Earth's total volume. This corresponds to roughly 0.47% of Earth's total mass.
Pure iron is 100% iron.
