The heat that remains inside the Earth from its creation and radioactive decay are its main heat sources.
The deep earth receives heat from three main sources: (1) heat left over from the planet's formation and accretion, (2) frictional heating brought on by denser core material sinking to the planet's centre, and (3) heat from radioactive element decay.
The energy produced when unstable atoms decay is known as radioactivity, and it is a substantial contributor to the Earth's heat. The main source are the radioactive isotopes of uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in the Earth's mantle.

Answer:
Below
Explanation:
The centers pushed against one another and rose.
When the books pushed up, it resembled real life converging tectonic plates which collide to create the tallest mountain ranges in the world (Like the Andes and Mt. Everest)
I would make sure all the bookshelves, wall hangings, and other things of that sort are anchored to the wall in preparation. I would also have an emergy go-bag and a plan with my family in case we got seperated. During the quake I would get underneath a table.
32%=0.32=8/25
66%=0.66=33/50
75%=0.75=3/4
50%=0.50=1/2

Answer:
the population was 121.86 in 2015
Northeastern United States is the region next to the Great Lakes (for example: lake Ontario) - and in fact they form the border between the Northeastern United States and Canada. (Perhaps" Great Lake region" fits better the gap - the gap needs a phrase in singular form).
