What else can I help you with?
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 happens as a result of molten rocks building up pressure under earths crust?
An erupting volcano occurs when the pressure of the molten lava beneath becomes too great.
Why are granitic and andesitic rocks as plentiful as they are on Earth?
Granitic and andesitic rocks are plentiful on Earth because they are primarily formed by the cooling and solidification of magma beneath the Earth's crust. These rocks are commonly found in continental crust due to the process of subduction, where oceanic crust is forced beneath the continental crust, leading to the melting and formation of granitic and andesitic rocks.
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.
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?

What does rocks in earths mantle contain a higher percentage of what than rocks in earths crust?
iron and magnesium
What are Igneous rocks that cool quickly beneath Earth's crust called?
Igneous rocks that cool quickly beneath earth's crust are known as intrusive rocks. These rocks will form from magma which will cool and solidify quickly.
What is the definition rock-forming minerals?
one of the common minerals that make up most of the rocks of the earths crust
What 2 types of rock are most common beneath the earths crust?
The two most common types of rock beneath the Earth's crust are basalt and granite. Basalt is an extrusive igneous rock that forms from the cooling of magma on the Earth's surface, while granite is an intrusive igneous rock that forms from the slow cooling of magma beneath the Earth's surface.
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 materials are the earths crust made of?
it is made of rocks
How common is uranium in the earths crust?
Crustal rocks: 2-3 ppm Sea water: cca. 3,3 ppb
