Potassium makes up about 2.6% of the Earth's crust by weight, making it the 7th most abundant element. In terms of its abundance in the Earth's overall composition, it accounts for about 0.25% of the total mass of elements in the planet.
The Earth's crust is about 40 km thick on average. It consists of the outermost solid shell of the Earth and is divided into tectonic plates that float on the semi-fluid asthenosphere below.
Cobbler has at least four definitions... 1) a person who mends shoes and boots 2) a clumsy person 3) an iced alcoholic drink 4) a deep pie with a thick top crust.
The Earth has a layered structure consisting of the inner core, outer core, mantle, and crust. The inner core is solid iron, the outer core is liquid iron, the mantle is mostly solid but can flow like a very thick liquid over long timescales, and the crust is the Earth's thin outer shell where we live. This structure is known as the "D-layered Earth model."
Francis of Assisi was born into a wealthy family, so he was originally part of the upper class. However, he renounced his wealth and embraced a life of poverty and simplicity, eventually founding the Franciscan Order which emphasized humility and service to the poor.
The Earth's crust is primarily made up of oxygen (46.6%) and silicon (27.7%), with silicon being the second most abundant element in the crust.
One is silicon, but I don't know the other:(oxygen
Oxygen is the most abundant element in Earth's crust, making up about 47% of its mass. Silicon is the second most abundant element, comprising approximately 28% of the crust's mass.
The two elements that make up the greatest percentage of Earth's crust by mass are oxygen and silicon. Together, they account for about 75% of the crust, with oxygen making up approximately 46% and silicon about 28%. These elements primarily combine to form silicate minerals, which are the most abundant in the Earth's crust.
47 % oxygen & 27% silicon.
Earth's crust is mostly made up of Silicon and Oxygen
Silicates are the mineral group that make up the highest percentage of Earth's crust, accounting for about 90% of the crust by volume. They are composed of silicon and oxygen, the two most abundant elements in the Earth's crust.
The most abundant element in Earth's crust is oxygen, making up about 46.6% of the crust by weight.

The three most common elements in Earth's continental crust are oxygen, silicon, and aluminum. In the oceanic crust, the predominant elements are oxygen, silicon, and magnesium. While oxygen and silicon are abundant in both types of crust, aluminum is more prevalent in the continental crust, whereas magnesium is more common in the oceanic crust.
The two most abundant elements in the Earth's crust are: Oxygen (46.1%/461,000ppm), and Silicon (28.2%/282,000ppm).
