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 type of rocks make up the earths crust?
The Earth's crust is primarily made up of igneous rocks such as basalt and granite, as well as sedimentary rocks like sandstone and limestone. Metamorphic rocks, which are formed from other rock types through heat and pressure, are also found in the Earth's crust.
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.
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 percent of the earth's crust is sedimentary rock?
Sedimentary rock; this is because the earth is constantly going through the rock cycle and both igneous rock and metamorphic rock have a lot to deal with under the earths surface and sedimentary rocks doesn't it just builds and builds over time which creates 75% of rock the covers the earth surface.
Are sedimentary rocks evenly distributed through out the earths crust?
yes
Basic material of the Earth's crust?
The basic materials of the earths crust are; silicate rocks, primary granite, igneous, metamorphic, and sedimentary rocks.
Why is there no sedimentary rock deep in the earths crust?
Sedimentary rocks get transformed into metamorphic and eventually igneous rocks in deep earth's crust.

What is the first step in the rock cycle turning metamorphic and igneous rocks into sedimentary rocks?
The first step in the rock cycle that turns metamorphic and igneous rocks into sedimentary rocks is weathering. Weathering breaks down rocks into smaller pieces through physical or chemical processes. These smaller rock fragments are then transported and deposited as sediment, eventually forming sedimentary rocks through compaction and cementation.
What provides geologist with evidence of earths past including geologic events and life forms?
The rocks of Earth's crust, especially sedimentary rocks

What percent of earths crust is made up of sedimentary rocks?
Approximately 75% of Earth's crust is composed of sedimentary rocks. These rocks are formed by the accumulation and cementation of mineral grains, organic matter, or chemical precipitates over time. Sedimentary rocks cover vast areas of the Earth's surface and provide valuable insights into the planet's geological history.
What is the class the includes sedimentary rocks which are deposited from a solution made by organic processes?
Biochemical sedimentary rocks.
What is a class that include sedimentary rocks which are deposited from a solution made by organic process?
Biochemical sedimentary rocks.
What makes up about 95 percent of the rocks in earths crust?
Igneous and metamorphic rock make up 95% of the rocks in Earth's crust. Only a thin layer is made up of sedimentary rock.
