Differences and similarities between igneous , metamorphic , and sedimentary rocks . sedimentary rocks are formed by weathered sediment using cementation or precipitation on Earth's surface . Metamorphic rocks are formed by changes of pressure and temperature within Earth's surface .
The work done is 137 joules.
Lifting opposes the acceleration of gravity, which is 9.8 m/sec/sec.
20 x 0.7 x 9.8 = 137 J (kg-m2/sec2)
Sedimentary rock forms *over time,* which means that those rocks had to form over millions of years, proving that the Earth has been forming and changing all this time.
