What percent of rocks on earth are sedimentary?
8%
Why sedimentary rocks could not have been the first rocks on earth?
water is needed, and long periods of deposit of sediment at the bottom, to form the sedimentary rocks. A hot, molton earth could not have created such rocks.
How does the volume of sedimentary rocks in Earth's crust compare with the volume of igneous rocks in the crust?
75% Igneous 5% Sedimentary
What are the the three classes of rocks?

What type of rock can only form on or near earths surface?

How do metamorphic rocks turn into a sedimentary rocks?
they cool and solidify on the earth's crust.
What is a Sedimentary rock?
Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding.
What temperature is sedimentary rock formed at?
Sedimentary rocks can be formed at any temperature found on the surface of the Earth. Diagensis of sedimentary rocks occurs at temperatures up to the formation of chlorite (200C) from then on they are metamorphic rocks.
