-All life in the universe that we know of, occurs there. -The crust is the coldest layer of all the layers of Earth. - The crust makes up less than 1% of the Earth's mass. - on average, it's about 27 miles thick, but can range from 2-70 miles. -The crust is composed of solid, brittle, igneous, metamorphic, and sedimentary rock. The main mineral group making up the rock of the crust are silicates, which include feldspars, micas, and quartz. -The temperature of Earth's crust can range from -70 degrees Fahrenheit to +750 degrees Fahrenheit depending on location and depth. Higher temperatures would be recorded in regions of crustal melting from magmatic intrusions. Technically, regions heated by magmatic intrusions are still crustal rock, and could reach well over 1,000 degrees Fahrenheit. -The majority of the crust is oceanic crust, basaltic in nature.
The earths crust is in constant motion And constantly being made , by volcanos and molten lava that seeps up from the earths depths - and earthquakes happen when two tectonic plates grind together or pull Apart
crust is moving at all times it has a pattern of solid liquid solid(core) 12 tectonic plates crust-avg of 17 mi mantle-avg of 1800 mi core-i forgot but i know its about the size of mars highest point mt Everest i think 5.6-6 mi high lowest point Marianas trench little more than 7 mi deep earth is slightly pear shaped the north pole is warmer cause the sun is out for days or months
