Composition of Solid Earth A Reynolds’ Production 2010
Title your Journal Page Element Composition of Solid Earth 19
Hey Fred! Do you Know The Elements of Earth Sure do, it’s one of the Nations in my favorite TV show. Not quite what we’re talking bout here Fred.
The Components that make up the Solid Earth Are elements found on the periodic table. They can be metals, nonmetals, and even metalloids. Oxygen is the most abundant chemical element in rocks in Earth's crust, making up about 47 percent of the weight of all rock. Ohhh, those elements
But then wouldn’t Earth be a Gaseous Planet? Your thinking is correct, but oxygen is in a group known as the “Rock-Forming” elements. Oxygen is also found in Water, think- Ice/Snow which is solid Earth at both Poles….
Composition Pie Chart By percent, the Earth breaks down as follows: Oxygen-O2 46.6% Silicon-Si 27.7% Aluminum-Al 8.1% Iron-Fe 5.0% Calcium-Ca 3.6% Sodium-Na 2.8% Potassium-K 2.6% Magnesium-Mg 2.1% others 1.6%

Looking at the Periodic Table Notice that the Largest portion of Elements in our Earth come from the first 20 elements in the Periodic Table
Element Composition of Solid Earth 19 I. Composition of Solid Earth Chart II. Oxygen makes up nearly 47% of the Earth’s Crust III. Silicon makes up nearly 28% of the Earth’s Crust Limited # of elements % Oxygen47 Silicon28 Aluminum8 Iron6 Calcium4 Magnesium2 Sodium2 Potassium2 Other Earth's Crust1
Limited Number of Elements So there are mainly 8 elements that make up the Solid Earth…. What about the other 110 elements? Those element are RARE. Which is why they are so precious. Like Gold…Silver….
Layers of the Earth Composition Notice Si is in the Lower Mantle and the Inner Core as well as the crust.
and that’s all Folks…. Keep this Chart in your Journal. We will practice making pie charts and/or bar graphs to learn the compositions of other things too.
