/media/bill/PROJECTS/Expanding Earth hypothesis.txt www.BillHowell.ca 04Sep2018 initial - idea from 2-3 weeks ago Do sedimentary layer thicknesses reflect th growth of the Earth? *************************** 05Sep2018 What is the total thickness of all sedimentary layers (on average globally)? It doesn't look like sedimentary deposits come anywhere near the doubling of Earth's diameter. Neal Adams pursued other possibilities. https://en.wikipedia.org/wiki/Earth_radius 6,371 km (3,959 mi) https://en.wikipedia.org/w/index.php?search=Earth+circumference&title=Special:Search&go=Go&searchToken=7heijs8zq7spx056tsg4lfiff actual circumference at the equator is about 40,075.16 kilometres (24,901.55 mi) my guess actual D_earth diameter of Earth (~12,000 miles 4,000 miles (I guessed wrong!!) C_earth circumference of Earth 26,000 miles (25,000 miles @ equator) R_earth ~= 4,000 miles, twice as large now -> say 2,000 miles 200My ago * 5,280 ft/mile = ~10.5*10^6 ft https://www.britannica.com/science/oceanic-crust Oceanic crust is about 6 km (4 miles) thick. It is composed of several layers, not including the overlying sediment. >> wow! https://www.answers.com/Q/What_is_the_average_thickness_of_oceanic_crust What is the thickness of the crust? Oceanic crust is typically 6-10 km thick. Continental crust is typically 35-40 km thick, but can be a lot thicker below mountains. High mountains also have deep roots that enable them to "float" higher on the Asthenosphere. The crust there can be up to about 70 km thick or more. Note that not all crust covered by the sea is oceanic crust. Some continental shelves extend beyond the part of the continent that is above water. For example between Australia and Papua New Guinea and between Malaysia / Cambodia / Indonesia. The satellite view of Maps.google.com clearly shows how the continental shelf is extended beyond the landmass.
