## Maths Error

"Estimates of the electricity generating potential of geothermal energy vary six–fold, from .035 to 2 TW depending on the scale of investments." - That's a factor of sixty, not six. — Preceding unsigned comment added by 66.61.117.39 (talk) 02:53, 4 September 2010

"Earth's internal heat is thermal energy generated from radioactive decay and continual heat loss from Earth's formation.[3] Temperatures at the core–mantle boundary may reach over 4000 °C (7,200 °F).[4] The high temperature and pressure in Earth's interior cause some rockS to melt and solid mantle to behave plastically, resulting in portions of mantle convecting upward since it is lighter than the surrounding rock. Rock and water is heated in the crust, sometimes up to 370 °C (700 °F).[5]"

Notice I added an S to rocks ^^^^^^^^^^^^^ 46.226.49.234 (talk) 15:24, 24 May 2016 (UTC)

Not done the Earth's interior is made of rock (without an s) as it is an "uncountable noun", "A noun that cannot be used freely with numbers or the indefinite article, and which therefore takes no plural form."
Small pieces of the rock core are called rocks (plural), as they are countable - so in this usage rock is correct.
For a fuller explanation of this, please see the first usage of rock as a noun here and an explanation of uncountable nouns here - Thanks - Arjayay (talk) 16:08, 24 May 2016 (UTC)
