What is compression in plate tectonics?
it is the movement of the earths crust. it moves inwards towards other plates so the earths crust moves upwards therefore forming mountains, volcanoes etc
What are some minerals in silicates?
Some minerals in silicates include quartz, feldspar, mica, amphibole, and pyroxene. These minerals are characterized by their crystalline structure composed of silicon and oxygen atoms arranged in tetrahedra.
Is it true that earths crust movement has been taking place only during the past 1000years?
No, Earth's crust movement has been occurring for billions of years as part of the process of plate tectonics. The movement of the Earth's crust has shaped the planet's surface and continues to do so over long geological timescales.
Where on earth are minerals found?
Minerals make up the rocks of earth, so minerals are found wherever there are rocks at the surface. Water too is a mineral so this includes the oceans.
In which layer of the Earth is Quartz found?
Quartz is mainly found in and on the surface of the continental crust. Quartz is igneous, so of course it originates from somewhere within the crust. Quartz is one of the most common minerals found in beach sand.
How do you get silicon out of earths crust?
Silicon is typically extracted from silica, which is found in the Earth's crust as quartz. The most common method to extract silicon involves heating silica with carbon in an electric arc furnace to produce silicon and carbon monoxide gas. This process is known as the carbothermic reduction of silica.
Why are many minerals silicates?
Many minerals are silicates because silicon and oxygen are the two most abundant elements in the Earth's crust. Silicates form when silicon and oxygen combine with other elements such as aluminum, potassium, or magnesium, resulting in a wide variety of mineral compositions and structures. This abundance of silicon and oxygen in the Earth's crust contributes to why silicate minerals are so common.
Which is thicker earths crust or lithosphere?
the lithosphere and the crust of the earth are the same lithosphere is another word for crust so the thickest is both of them.
What minerals make up 90 of the earths crust?
There are ten minerals that are so common that they make up 90% of the Earth's crust. These are quartz, orthoclase, plagioclase, muscovite, biotite, calcite, dolomite, halite, gypsum, and ferromagnesian minerals.
What is vertical Positioning of the Earths crust so that gravitational an buoyont forces balance called?
Isostasy
Which element is the abundant in the earths crust?
The most common chemical elements in the crust are oxygen (46.6%), silicon (27.7), aluminum (8.1), iron (5.0), calcium (3.6), potassium (2.8), sodium (2.6), and magnesium (2.1).Oxygen is a non-metal and silicon is a metalloid - so the most common metal is aluminum.
Why is there so much oxygen in Earths crust?
Oxygen, though usually a gas, is still in a molecule form and can be bonded to with any other molecule that is able to do so. Oxygen is a very common element in the crust because many rocks and more importantly minerals that make up those rocks use it in there atomic bonds. A simple example is Quartz, SiO2 So each single structure has one silicon atom and two oxygen atoms.

Why is earths crust so thick under mountains than in in other places?
it's so thick because there is more rock and dart.
How do humans use geothermal energy?
people dont use geothermal it is in the earths crust so people dont use geothermal
