The Earth's crust has an average depth of about 30-50 km. It is primarily composed of oxygen, silicon, aluminum, and iron, with varying amounts of other elements. The temperature of the crust increases with depth, ranging from about 200°C at the surface to over 800°C at the base of the crust.
What else can I help you with?
What are the earths layers of rock classified by?
The Earth's layers of rock are classified by their composition and physical properties. The main layers are the crust (continental and oceanic), mantle, and core (outer and inner). These layers are distinguished by differences in chemical composition, density, and temperature.
What effects are metamorphic rocks formed by?
Metamorphic rocks are formed by the effects of high temperature, pressure, and/or chemically active fluids. These forces cause existing rocks to recrystallize and change their mineral composition without melting.
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
What elements are found in a high proportion in Earths crust?
The Elements found in a high proportion in the Earths crust are, 1. Oxygen. 2. Silicon. 3. Aluminum. 4. Iron. 5. Calcium. 6. Sodium. 7. Potassium. 8. Magnesium.
What kind of graph would be best to compared the different elements that make up the earths crust?
A stacked bar graph would be best to compare the different elements that make up the earth's crust. Each bar would represent the total composition of the crust, and different segments of the bar would represent the proportion of each element. This allows for easy comparison of the relative amounts of each element.
What is the general composition of earths continental crust?

What composition is earths crust?
oceanic crust is made of basalt while continental crust is made of silica rich rocks like granite.
What is the earths under crust surrounded by?
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
What is the earths crusts tempiture?
The earths crust varies. There is no temperature because it varies from cold to hot.
What do scientists study to learn about the temperature inside the earths crust?
Scientists study seismic waves to learn about the temperature inside the Earth's crust. By analyzing the speed and direction of these waves as they travel through different layers of the Earth, scientists can infer information about the temperature and composition of the Earth's crust.
A relative age of the rocks of the earths crust can be determined by using the laws of?

What is the composition of earths oceans?
Many different minerals are found in oceanic crust. Feldspar, basalt, pyroxene, and other molten rock materials make up the composition of the ocean's crust.
