What else can I help you with?
In earth's crust what are two types of crust?
sial and sima - sial is surface crust on land, made of silicate and aluminium. sima is the deep crust found in oceans, made of silicate and magnesium
The crust is only what of earths thickness?
half of earths layer
What is the comostion of the earths crust?
Mostly iron, oxygen, silicon, magnesium, sulfur, nickel, and calcium.
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.
How do floods affect the earths crust?
it gets soggy
Which part of the earth is made mostly of silicate minerals?
The Earth's crust is made mostly of silicate minerals. Silicate minerals are the most abundant minerals in the Earth's crust and are composed of silicon and oxygen atoms.
What are the two most common silicate minerals in earths crust?
Quartz and feldspars are the most common silicate minerals of the crust.
What is the percentage of the earths crust made up of non silicate minerals?
Only 10% of the Earth's crust is composed of non-silicate minerals. Examples of non-silicate minerals are barringerite, nickel phosphide, taenite and suessite.
Is the earth mostly made out of silicates?
Yes, the Earth's crust is primarily composed of silicate minerals, which make up the majority of the planet's surface. Silicates are minerals containing silicon and oxygen, forming the most abundant group of minerals in the Earth's crust.
What are the most common minerals located in earths crust?
The most common minerals found in Earth's crust are quartz, feldspar, and mica. These minerals make up a significant portion of the Earth's continental crust and are essential components of many rock types.
Why earth crust is solid?
Earth's crust is composed mostly of silicate minerals, which have high melting points. Surface temperatures are not nearly hot enough to melt these minerals.
Which group of minerals of the most abundant in the Earth's crust?
The silicate group of minerals comprise the largest percentage of the Earth's crust. Silicate minerals include quartz, feldspars, and micas.
Why are silicate minerals the most abundant in Earth's crust and mantle?
Silicate minerals are the most abundant in Earth's crust and mantle because silicon and oxygen, the main components of silicate minerals, are the most abundant elements in the Earth's crust. This abundance of silicon and oxygen leads to the formation of silicate minerals through various geological processes, making them the most common type of minerals found in the Earth's crust and mantle.
Types of minerals that contain oxygen and silicon?
Silicate minerals are a group of minerals that contain oxygen and silicon as their primary constituents. Examples of silicate minerals include quartz, feldspar, mica, and amphibole. These minerals are the most abundant in the Earth's crust.
Do sulfides constitute the largest group of minerals in Earth's crust?
No the most abundant minerals in the earths crust are Silicates due to the over all abundance of the elements Oxygen and Silicon. A good example of a Silicate is Quartz. The overall composition of the Earth is mostly iron (Fe), oxygen (O), silicon (Si), magnesium (Mg), nickel (Ni) and sulfur (S). Most of the mass of the Earth occurs within the mantle which is largely ferromagnesium silicate minerals olivine and pyroxenes.
What compose most of Earth's continental crust?
Silicate minerals compose the crust.
What is the most common group of mineralswhat percentage of the crust do they make up?
The most common group of minerals in Earth's crust are silicate minerals, which contain silicon and oxygen. Silicate minerals make up about 90% of the Earth's crust.
