What is the earths crust made up of?
The Earth's crust is mainly composed of oxygen, silicon, aluminum, and iron, along with smaller amounts of other elements like calcium, sodium, and potassium. It is divided into oceanic crust, which is thinner and denser, and continental crust, which is thicker and less dense.
What do you call the layer of the solid unbroken rocks in the earths crust?
The layer of solid unbroken rocks in the Earth's crust is called the lithosphere.
How would you use small rocks pieces of cardboard and a tub of water to model earths lithosphere?
You can use the small rocks to represent Earth's crust, the cardboard pieces to represent the tectonic plates, and the tub of water to simulate the asthenosphere beneath the lithosphere. By moving the cardboard pieces around on top of the small rocks in the water, you can demonstrate how the plates interact with each other and how they can cause phenomena like earthquakes and volcanoes.
What is the most abudant element in earths crust?
The most abundant element in Earth's crust is oxygen, making up about 46.6% of the crust by weight.
What are the most common type of rock found at the earths surface and in the earths crust?
The most common type of rock found at the Earth's surface and in the Earth's crust are sedimentary rocks. These rocks are formed from the accumulation and lithification of sediments such as sand, mud, and organic debris. Sedimentary rocks cover about 75% of the Earth's surface.

What makes close to 95 percent of the rocks of earths crust?
Silicates make up close to 95 percent of the rocks in the Earth's crust
Basic material of the Earth's crust?
The basic materials of the earths crust are; silicate rocks, primary granite, igneous, metamorphic, and sedimentary rocks.
What is the point in earths crust where the rocks first start to break?
Focus
Are sedimentary rocks evenly distributed through out the earths crust?
yes
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
Large plutonic rocks called?
Batholiths are large plutonic rocks that form deep within the Earth's crust. They are composed of a variety of minerals such as feldspar, quartz, and mica. Batholiths are typically associated with mountain-building processes and can cover extensive areas of several hundred to thousands of square kilometers.
How did rocks get on earth?
they were and aree forced through earths crust in the form of lava.
