The most common mineral group in Earths crust is the?
silicate mineral group, which includes minerals such as quartz, feldspar, mica, and olivine. These minerals make up about 90% of the Earth's crust and are the building blocks of most rocks.
Why are there 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.
Is quartz one of the most common mineral on earths crust yes it is?
The most common minerals are the silicates- and quartz is the most common silicate.
Only about 30 minerals are common in rocks What are they called?
The 30 common minerals found in rocks are known as rock-forming minerals. Some examples include quartz, feldspar, mica, and amphibole. These minerals make up the majority of the Earth's crust and are essential components of different types of rocks.
Thin layers of rocks and minerals on earths surface called?
These thin layers are called sedimentary rocks, which are formed from the accumulation and compression of sediments over time. Sedimentary rocks are one of the three main types of rocks found on Earth's surface, along with igneous and metamorphic rocks.
What is rock forming minerals?
one of the common minerals that make up most of the rocks of the earths crust
What element is abundant in earths crust and combines with oxygen to form rocks and minerals?
Silicon
What is the definition rock-forming minerals?
one of the common minerals that make up most of the rocks of the earths crust
Approximately how many of the 2500 minerals form the common rocks of the earths crust?
There are actually well over 4,000 known minerals as of 2010; of these, about two dozen form the bulk of the rock of the earth's crust.
What is the mineral forms?
one of the common minerals that make up most of the rocks of the earths crust
What is rock-forming mineral?

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.
Why do you think geologists use drills bits covered with small diamonds to drill earths crusts?
Because they have to get through the minerals and rocks in the earths crust.
what are plants that make up earths crust?
The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.
What are the rocks that make up the earths crust?
the crust and the core
What is the earhs crust made of?
The Earth's crust is made primarily of solid rocks, including igneous, metamorphic, and sedimentary rocks. It also contains minerals like quartz, feldspar, and mica. Additionally, the crust may have small amounts of water, gases, and organic materials.
Why do minerals only occur in metamorphic rocks?
because of the metamorphism when temperature and pressure inside earths crust change that were present in the rock when it formed
