What are the symbols that make up about 75 percent of the earths crust?
About 75 percent of the Earth's crust is composed primarily of eight elements: oxygen (O), silicon (Si), aluminum (Al), iron (Fe), calcium (Ca), sodium (Na), potassium (K), and magnesium (Mg). Among these, oxygen and silicon are the most abundant, forming silicate minerals that dominate the crust. These elements combine in various ways to create a wide variety of minerals, including feldspars, quartz, and micas, which are key components of rocks.
How many elements make up 98 percent of earth's crust?
8 Elements make up earths crust like 27.7% Silicon (Si) 8.1% Aluminum (Al) 5.0% Iron (Fe) 3.6% Calcium (Ca) 2.8% Sodium (Na) 2.6% Potassium (K) 2.1% Magnesium (Mg) 46.6% Oxygen (O)
What percentage of the earths crust is made up of alkali metal?
Mg is 2.0% of Alkaline earth metals, as Ca is 3.6%..., equals 5.6%
What is the name of ca famous break in the earths crust that causes earthquakes to occur?
The famous break in the Earth's crust that causes earthquakes to occur is called a fault line. Movement along fault lines can result in earthquakes due to the build-up and release of stress between tectonic plates.
What elements make up earths crust?
The 8 most common elements in Earth's crust (by mass): 46.6% Oxygen (O) 27.7% Silicon (Si) 8.1% Aluminum (Al) 5.0% Iron (Fe) 3.6% Calcium (Ca) 2.8% Sodium (Na) 2.6% Potassium (K) 2.1% Magnesium (Mg) hope that helps!
