Question

temperature of sedimentary rocks​

Answer 1

Answer:

Explanation:

Lower Temperature (Near the surface T = 0-50oC) Lower Pressure (Near the surface P = 1 to several hundred atmospheres) Higher free water (there is a lot of liquid water near the surface, compared with deep in the Earth)

Answer 2

Answer:

Since many rocks and minerals are formed under conditions present deep within the Earth, when they arrive near the surface as a result of uplift and erosion, they encounter conditions very different from those under which they originally formed. Among the conditions present near the Earth's surface that are different from those deep within the Earth are:

Lower Temperature (Near the surface T = 0-50oC)

Lower Pressure (Near the surface P = 1 to several hundred atmospheres)

Higher free water (there is a lot of liquid water near the surface, compared with deep in the Earth)

Higher free oxygen (although O2 is the most abundant element in the crust, most of it is tied up bonded into silicate and oxide minerals - at the surface there is much more free oxygen, particularly in the atmosphere).
